Dryer won’t start

You might be wondering why your dryer won’t start despite all your efforts including giving it a good smack. Well, here are some reasons for that.

  1. Thermal fuse

The thermal fuse is what prevents your dryer from overheating. You will find it on the blower housing or the heat source of the dryer. If you have a gas dryer, it will be on the burner, and if yours is electric, then it is on the heating element.

  • You will want to check if the thermal fuse blew due to overheating. The fuse should have continuity, and it is not there if the electrical path is broken.
  • Test for continuity using a multimeter, and if it is blown, you need to replace it.

Remember that a blown thermal fuse could mean that the venting is blocked and you need to have it checked when replacing the thermal fuse.

  1. Door switch and start switch

The door switch makes a clicking sound when you close the door of the dryer. The start switch is what makes the dryer respond when you switch it on. You need to check if the two are working using the following method.

  • Switch on the dryer and close the door. If you hear a click sound, the door switch is perfectly okay.
  • Start the dryer and wait for it to respond. If there is humming and the dryer doesn’t start, then the start switch is not the problem. The start switch is the culprit if there is no response at all.

Test the door switch and start switch for continuity using a multimeter and if there is none, you should have them replaced.

  1. Drive belt and belt switch

For most dryers, the motor still works even when the dryer belt is broken. It’s only the drum that will not turn. Some dryers have a belt switch that shuts the power when the belt is broken. You need to inspect the drive belt and see if it is broken.

  • Switch on the dryer and listen if it is humming. If there is no humming, then your drive belt is the problem, and you should replace it.
  • Also, find out if your model comes with a belt switch and test it for continuity using a multimeter. Replace your belt switch if there is no continuity.
  1. Drive motor

The drive motor turns the drum together with the blower wheel to exhaust the air and starts humming when it has a problem. Since it is rarely at fault, check all other parts before you start looking for a replacement.

  • Inspect the blower for any blockages, and if there are none, the drive motor is guilty. If you suspect it for being the main problem, have it replaced.
  1. Incoming power problem

Check your power supply and see if it has a problem. If you use a gas dryer, unplug it from the source and plug in something else to test the gas outlet. If you have an electrical dryer, check the circuit breaker and fuses and use a multimeter to test if they are in good condition.

  1. Timer

Look at other common culprits and if everything else is working, use a multimeter to test the timer and remember to consult the wiring diagram. No continuity means you have to replace it.

  1. Main control board

The control board malfunctioning is a rare bird, and you have to be sure before you start looking for a replacement. First, check all other parts, and if they are working, you can have the main control board replaced.

Common causes for dryer stopped spinning and dryer drum not turning

  1. Drive belt

If you are wondering what it is just look for the long slender belt wrapped around the drum, tension pulley, and drive motor pulley. After using your dryer for a while, it will break and stop the dryer from turning.

Try turning your dryer by hand, and if it turns easily, the drive belt might be broken. Confirm by looking at it and replace the drive belt if it is broken.

  1. Drum roller and Drum support roller and axle and drum roller axle

In most dryers, there are two drum support rollers at the drum rear. Yours might also have two more at the front. These rollers have drum roller axles on them, and they need to spin freely for the dryer to work. If the rollers are worn out, they will not spin freely and will end up putting a strain on the motor making the dryer stop.

  • You need to remove the belt from the dryer and try rotating the drum manually. If there is difficulty moving the drum, inspect the drum roller axles and drum rollers for signs of wear.
  • If the rollers are wobbling, you need to replace them.

We recommend that you replace all the axles and rollers as soon as you notice one or more being worn out.

If your roller shaft is in good condition, clean the shaft and install the new rollers.

  1. Drum glide, slide or pad

If the dryer stops spinning during the cycle, these small plastic pieces supporting the dryer front are the culprits. The drum slides on these pads when it spins, and they might start wearing out over time. When this happens, the motor will strain and shut down, and the dryer will stop turning.

Inspect the drum glides for signs of wear and replace the entire set if one or more are worn out.

  1. Drum bearing or drum support bearing

The drum support bearing is what supports the rear of the dryer drum. When it gets worn out, the motor begins straining and stops during a cycle.

  • Remove the dryer belt and attempt turning the drum manually to see if the bearings are the problem. If there are free rotations, then you need to look elsewhere since they are not defective.
  • If you hear an annoying grinding or squealing sound or there is difficulty turning it, you need to inspect and replace the drum support bearings.
  1. Drive motor

The drive motor turns the drum and blower wheel to exhaust the air. If the dryer runs, shuts down and runs again, the motor could be overheating, and it cools by shutting down.

  • Remove the belt from the motor and see if there is anything blocking it. Try to rotate the drum while the belt is still removed and find out what is causing the bind if there is no free rotation.
  • If there is free rotation and the blower wheel is clear, the drive motor might be the issue, and it needs to be replaced.
  1. Dryness control board

When clothes reach a certain level of dryness, the dryness control board shuts off the dryer. If the part is defective, your clothes will not dry properly since it will shut down before they finish drying.

However, check all other parts and if they are all working, you can have the dryness control board replaced.

Dryer taking too long and dryer won’t stop

  1. Cycling thermostat

The temperature in the dryer is regulated by the cycling thermostat, and the dryer will not heat if it has a problem and will take too long.

Test all other parts and if they are all working, use a multimeter to test for continuity and replace the cycling thermostat if there is none.

  1. Air flow problem

If the dryer vent is clogged, the airflow will be restricted and the drying time will be longer. All you need to do to make your dryer better is to clean the vent system once a year and your dryer will be at its best performance.

  1. Heating element and heating element assembly

Air is warmed before it enters the drum by the heating element. The heating element assembly warms the air as it goes through it. The dryer will take longer to finish a cycle if any of them burn out since it will refuse to heat.

Test for continuity using a multimeter and if there is no continuity, have the heating element and heating element assembly replaced.

  1. Blower wheel

Air is drawn into the dryer drum by the blower wheel together with the drive motor. Sometimes, small items get caught in the blower wheel causing obstructions. The blower wheel will also wobble on the motor shaft if the wheel sleeve starts wearing out and this will increase the drying time.

  • Remove the dryer vent and assess the airflow strength. If it is weak, check for any blockages.
  • If there are no blockages, rotate the blower wheel and replace it if it wobbles.
  1. Lint filter

Clean the filter to remove any residue and increase the air flow.

  1. Moisture sensor

When your clothes are dry, the control board receives a message from the moisture sensor. Any malfunction makes it send the message that the clothes are still wet even though they are already dry.

Check all other parts and if they are all working, replace the moisture sensor.

  1. Gas valve solenoid

There are two or more gas valve solenoids on gas dryers. They allow gas to flow into the burner by opening the valves. When they fail, the drying time is increased since it happens during a cycle. The burner will also run intermittently, and the dryer will not stop.

Ignite the gas, and if the igniter glows and goes out without igniting the gas, then your solenoids need to be replaced. Replace the entire set if one or more is defective.

  1. High limit thermostat

If the dryer starts overheating, the high limit thermostat shuts off the burner. If it has a problem, it will shut off the dryer even when there are no signs of overheating.

  • Test all the other parts if they are working and if there is no problem, test the high limit thermostat for signs of continuity using a multimeter.
  • If there is no continuity, have the unit replaced.
  1. Thermistor

For your clothes to dry evenly, the heat must be cycled, and the temperature needs to be monitored. Some dryers have thermistors that do that and should be replaced if they malfunction.

  1. Timer

The motor on the timer rotates it to the off position on the control panel. If it is spoilt, the dryer will not stop since it will not rotate. Have it replaced if it has any problem.

Dryer overheating

  1. Blower wheel

Air is drawn into the dryer drum by the blower wheel together with the drive motor. Sometimes, small items get caught in the blower wheel causing obstructions. The blower wheel will also wobble on the motor shaft if the wheel sleeve starts wearing out and this will make the dryer wheel overheat.

  • Remove the dryer vent and assess the airflow strength. If it is weak, check for any blockages.

  • If there are no blockages in the blower wheel, rotate the blower wheel and replace it if there is any wobbling.

  1. Heating element and heating element assembly

Air is warmed before it enters the drum by the heating element. The heating element assembly warms the air as it goes through it. If they shorten even partially, they will continue producing heat even after the dryer has reached the optimum temperature.

Determine if they are the problem by testing for continuity to the case using a multimeter. If there is continuity, they have shortened out and need to be replaced.

  1. Air flow problem

Clean the venting system to prevent any blockages and ensure your dryer remains at its prime.

  1. Cycling thermostat

The cycling thermostat maintains proper air temperature by cycling the heat. If it stops working, the dryer overheats since it will keep the heat on for too long.

Test it using a multimeter and replace it if there is no continuity.

  1. Felt seal

The felt seal prevents heat from escaping the drum. The dryer will overheat if it the seal is missing or worn out since the heat will not escape using the proper way.

Ensure the seal is properly covering the dryer drum and replace it if it is worn out or missing.

Dryer not heating

  1. Cycling thermostat

The cycling thermostat maintains proper air temperature by cycling the heat. If the thermostat malfunctions, the dryer will not heat. Use a multimeter to test the thermostat for continuity and if there is none, have it replaced.

  1. Thermal fuse

The thermal fuse gives the dryer protection from overheating and can be found on the blower housing or heat source. There should be continuity for the fuse to be working. If there is no continuity after testing using a multimeter, replace the thermal fuse.

Also, check for any restrictions on the exhaust vent since a blown thermal fuse is one of the signs, and the venting should always be checked when replacing the thermal fuse.

  1. Heating element and heating element assembly

Air is warmed before it enters the drum by the heating element. The heating element assembly warms the air as it goes through it. If they burn out, the dryer will not produce any heat.

Test for continuity using a multimeter, and if there is none, they should both be replaced.

  1. Gas valve solenoid

The dryer will not start heating if the gas valve solenoids have a problem since there will be no gas coming into the burner. If the gas valve solenoid is defective, the igniter will go on and off without igniting the gas burner, and the entire set should be replaced.

  1. Flame sensor

When there is a flame on the gas burner, the flame sensor detects it, and the dryer will not heat if it is not working. Before you go pointing fingers at the flame sensor, first check the igniter and thermal fuse.

Then you can test for continuity at room temperature using a multimeter if you find they are in working condition. If there is no continuity, you can replace the sensor.

  1. High limit thermostat

The high limit thermostat is responsible for shutting off the burner if it overheats. If it has a problem, it will shut off the burner even when it is not producing enough heat. Check all other parts before you test the thermostat for continuity, and if there is none, the unit should be replaced.

  1. Main control board

There is no clear way of testing the main control board since t rarely malfunctions. You can only check all other parts if they are working and if there are no defects, replace it. You can try looking for any sign of shortened components.

  1. Incoming power problem

Check the power source in your dryer and ensure it is in good condition. If you have an electric dryer at home, you will find there are two legs that make it run efficiently. If one of the breaker legs trips, the dryer will continue working, but no heat will be produced. Measure the voltage outlet using a multimeter and check the fuse box for continuity.

  1. Timer

A defective timer will make the dryer not heat since it might remain in the off position. Check all other parts, and if they are in good condition, you can have the timer replaced.

  1. Igniter

The dryer will not heat if the igniter is not working since the gas will not be ignited. Test the igniter for continuity using a multimeter and replace it if there is no continuity.

Dryer keeps tripping the breaker

  1. Weak circuit breaker

Circuit breakers weaken over time making them more susceptible to tripping even when there is normal amperage. If all other parts are in working condition, have the circuit breaker replaced.

  1. Heating element and heating element assembly

At times, the heating element and heating element assembly can short out the entire heater housing tripping the circuit breaker. If this happens, each terminal should be tested for continuity to the case using a multimeter. If there is continuity, they should be replaced since they will have shortened out.

  1. Drive motor

If the drive motor shorts internally, it may trip the circuit breaker. Test it for continuity using a multimeter and replace it if you find the motor windings have shortened out.

  1. Terminal block

As careful as you are, sometimes the power cords will get loose, arc and destroy part of the terminal block. One or more of the wires can short against the body of the dryer tripping the breaker. The wires should be properly placed and secured to prevent this from happening.

Dryer makes a lot of noise

Here are the common culprits when your dryer starts making noise out of nowhere.

  1. Drive belt

The drive belt is a long slender belt you will find on the drum, tension pulley and drive motor and it wears out after some time. When this happens, you will hear a noise when turning. Inspect the belt if it is worn out and have it replaced.

  1. Drum roller axle, drum roller, drum support roller and axle

In most dryers, there are two drum support rollers at the drum rear. Yours might also have two more at the front. These rollers have drum roller axles on them, and they need to spin freely for the dryer to work. If the rollers are worn out, they will not spin freely and will end up putting a strain on the motor making the dryer make a squealing or grumbling noise.

If you inspect the rollers and find they are worn out, replace the entire set for the dryer to work quietly. The roller shaft can be reused only if it is in good condition and has been cleaned before roller installation.

  1. Blower wheel

Air is drawn into the dryer drum by the blower wheel and the drive motor. Sometimes, small items get caught in the blower wheel causing obstructions. The blower wheel will also wobble on the motor shaft if the wheel sleeve starts wearing out.

Remove any obstruction from the blower wheel and if there are none and the blower wheel still wobbles, have it replaced.

  1. Drum bearing and drum support bearing

The drum support bearing is what supports the rear of the dryer drum. When it gets worn out, the motor begins producing a squealing or grumbling sound when the drum is turning.

  • Remove the dryer belt and try giving it a good turn manually to see if the bearings are the problem. If there are free rotations, then you need to look elsewhere since they are not defective.

  • If you hear any grinding or squealing sound or there is difficulty turning it, you need to inspect and replace all the drum support bearings.

  1. Maintenance kit

If you have no clue why your dryer is making noise, you can get a maintenance kit that has replacements for the common defective parts. Ensure you get a maintenance kit for your model number since they are the perfect fit.

  1. Drum slide, glide or pads

These small pieces of plastic support the front of the drum and the dryer will become noisy when they get worn out since the drum slides on them when rotating.

Inspect them for signs of wear and replace the whole set if one or more are worn out.

  1. Idler pulley and idler assembly

Inspect the idler pulley and idler assembly if they are worn out and replace them if it is the case. It is also recommended that you replace them when replacing the drive belt.

  1. Drive motor

Check all other components if they are in working condition since it is rare for the drive motor to be at fault. If they are all working, you can replace the drive motor since it is the faulty part.
