Why won't my dryer start?

1. The control panel is locked.

Some models have a control board that enables the user to “lock” the door switch. This prevents it from opening during a cycle or after the dryer timer has been set. The control panel can also prevent it from starting altogether.

If your door doesn't open, the control panel may be locked. Some models may display a key or padlock icon to indicate this. You can attempt to unlock it yourself using your owner's manual.

2. The start button was mis-pressed.

Test the start switch and ensure you're pressing it correctly. You may need to press the button firmly (or hold it down for several seconds) so the dryer will operate.

Some mis-presses can occur if you press a button with your fingernail instead of your fingertip. Moisture on the control panel can also interfere.

3. There’s a tripped circuit breaker or a blown fuse.

Whether you have a gas or electric dryer, it will require circuit breakers or household fuses to operate. If a fuse is loose (or a Ground Fault Circuit Interrupt [GFCI] outlet or circuit breaker trips), it won't start.

To check if there’s a problem, plug another device directly into the outlet and see if it turns on. If it doesn’t, there may be a blown fuse or tripped circuit breaker.

If you’re comfortable, you can test your breakers by turning them off and back on. Then, attempt to restart the dryer. If that doesn’t work, you may want to hire an electrician to fix any electrical problems that are preventing it from starting.

4. Certain parts aren’t intact.

Sometimes, the wires that power a dryer will become loose, which can cause operation problems. If you’re comfortable, you can disconnect the power. Then, make sure all power supply cord wires on the dryer terminal block are tightly screwed and intact.

The dryer plug should be firmly pushed into the wall’s electrical outlet. Some electric models will require a specific power supply to operate, such as a 240-volt outlet. If you don’t have this type of outlet, it’s safest to hire an electrician.

Because these power cord components deal with electricity, you may feel more comfortable when you hire a dryer repair professional. If you’re testing the parts, always disconnect the power to ensure your safety.

5. The door isn’t fully closed.

For some models, you’ll need to firmly close the door for it to latch and enable operation. Sometimes, extra clothes may prevent the door from closing all the way.

Pull the door open, and then re-close it firmly so it can latch correctly. Then, attempt to start the dryer.

In some cases, the door switch may be broken altogether. If you need to replace the door, hire an appliance repair professional who can obtain a manufacturer-approved part and install it correctly.

6. Parts weren’t installed correctly.

With some dryers, all parts need to be properly installed for the device to work. For example, improper installation of a bottom filter could prevent it from starting.

Check your manufacturer’s guide to determine the proper installation. For parts you’re having trouble correctly installing, hire an appliance installation professional.

7. The wrong cycle was selected.

Some dryers won’t start unless a specific cycle is selected. For example, with some Maytag or Whirlpool models, the Cycle Control knob must be set to Time Dry or Automatic cycles to start.

Make sure you’ve set the dryer to a drying cycle. Check your owner's guide, if needed.

8. The pump reservoir is full. 

Some dryer units, such as a compact heat pump dryer, will include a pump reservoir with a water level sensor. If the reservoir fills up to a certain level, it may shut off the dryer.

Water might fill up a reservoir if the water tank wasn’t properly installed or there are drain hose problems. If you’re not an expert in identifying issues with a water tank or discharge hose, hire a dryer repair person to troubleshoot.

9. The thermal fuse has blown.

The latest research from the National Fire Protection Association reports 13,820 home fires in the U.S. due to dryers from 2014 to 2018. To prevent fires, dryers contain a thermal fuse that will shut off the appliance if exhaust temperatures increase too much.

If your dryer shuts off and won't start, the thermal fuse may have been triggered due to a problem like a clogged exhaust vent or a too-hot heating element. You’ll need to replace a thermal fuse once it has been triggered. You can usually find it in the exhaust duct, inside the back panel.

Only troubleshoot, remove and replace a thermal fuse after you’ve shut off electrical power. To ensure safe and proper thermal fuse replacement, consider leaving this task to a repair expert.

10. The dryer motor has failed.

Dryers use a drive motor to rotate wet clothes as hot air circulates around them. The motor then helps eliminate moisture through the exhaust hose.

When a motor breaks, your dryer may fail to start. The motor will need to be replaced with a manufacturer-approved part, which requires expertise with specific tools and safety equipment. If you suspect the motor has failed, hire a professional.

FAQs.

When I press the start button on my dryer, nothing happens. What’s going on?

The dryer may fail to start for a variety of reasons. Ensure all of the following is happening:

• You’re pressing the start button correctly.
• The door is fully closed and latched.
• You’ve selected the correct setting.

If the dryer still doesn't turn on, there may be an issue with parts or the electric supply.

Why won’t my dryer start but has power?

If your dryer has power but won’t start, there are several potential causes:

• You may not have closed and latched the door fully.
• Certain components may not have been properly installed.
• It may not be set to a drying setting.
• The control panel may be locked.
• If you have a compact heat pump dryer, the water reservoir may be full.

If you’re unsure of the problem, consult a professional ASAP.

How do I reset my dryer?

Find directions to reset your dryer in your manufacturer’s guide. If you can't find it, here are some basic steps you can try:

• Turn the dryer off.
• Unplug it and turn the circuit breaker off.
• After the power is disabled, hold the power button for several seconds.
• Turn the circuit breaker back on and plug in the dryer.

How do I know if my dryer's thermal fuse is blown?

One sign a dryer thermal fuse is blown is that the dryer continues to operate and tumble without heat.

You can also test a thermal fuse with an electrical multimeter. To do this, remove the thermal fuse’s two wire leads. Set the multimeter to its lowest RX setting, and touch each wire terminal on the fuse. Any reading that is less than infinity means the thermal fuse is blown and will need to be replaced.
