How to Troubleshoot and Fix a Dryer That Will Not Start
If your dryer won’t start or turn on, you are in the right place! Sometimes it’s simply a matter of resetting your dryer, or unclogging its exhaust vent, but it can also be caused by a faulty part. A dryer that won’t start or isn’t turning on not only prevents you from doing your laundry but can also indicate a safety hazard. Parts like the thermal fuses and thermostats act as safety devices and can be the culprit for issues like this, but can also be signs of other issues with your dryer's airflow. Fortunately, we have a complete and expert-curated guide to help you find the different parts around your dryer that may be causing issues, and to help you figure out why your dryer isn’t starting or turning on, so you can get it back to normal as soon as possible.
How to Diagnose a Dryer That Will Not Start
The first thing you need to check if your dryer won't start is if your breakers are delivering power to your dryer or if its fuses are good. Our in-house expert technician, Chris, shows you which dryer parts you may need to look at next here:

FIX TIP
Resetting Your Dryer
Sometimes performing a reset of the control board is the best option for getting your dryer back in working order fastest. This can be done in many ways, depending on your model, but it’s best to figure out if your dryer resets through the use of buttons, by simply turning it off and waiting, or if it features a reset button.
Check Your Power Source
Your power source may ultimately be at fault for a non-starting dryer. Make sure to check not only your outlet, but also the breaker and fuses for any issues.
Power Cord Issues
In some cases of dryers not starting or turning on, the power cord can be the cause. Make sure to check your power cord for any abrasions, cuts, or disfigurations that might lead to a faulty connection to the outlet or the appliance.
Clogged Exhaust Vent
Depending on what model of dryer you have, if you have a vent that comes out of your dryer to expel hot air and particles, you might want to check it for blockages or clogs. As a built-in safety mechanism, many dryers that require vents will not start if the vent is clogged or blocked. This can be both a safety and an environmental hazard, too, since built-up particles can cause a fire if left unaddressed.
Common Parts You May Need to Replace
The list of parts below are the most common causes of a dryer not starting. More information, such as part descriptions, 3D renderings, and installation instructions, are available on the individual parts’ pages.
- Timer The timer determines the length of load cycles, and if it’s malfunctioning, it can cause your dryer to not work properly or at all.
- Electronic Control Board Because it acts like a motherboard does in a computer, issues with the control board can cause your dryer to not work properly or at all.
- Relay Board The relay board deals with the heating element and motor of your dryer, and if it isn’t working properly the dryer may not start.
- Drive Motor The motor is the main engine of your dryer, rotating the inner tub so that it dries your load of clothes evenly. If it’s damaged or bad, the dryer will not function.
- Door Switch This switch communicates with the control board to close and seal your dryer’s door before starting the cycle. If it’s bad, the dryer may not operate properly.
- Belt The belt is essential to the rotation of your dryer, and if it’s broken or damaged, your dryer may not start or function properly.
- Belt Break Switch The belt break switch is necessary to stopping your dryer if the belt breaks while the dryer is in use. If your dryer won’t start, it could be that the belt break switch needs to be replaced, especially if the belt is not in good condition.
- Push-to-Start Switch For some dryer models, a push-to-start button is used to commence the drying load. If it’s bad, your dryer won’t recognize that it’s been pushed and will not start.
- Selector Knob This knob, located on the user interface, allows you to make selections for your drying load. If it’s broken or damaged it can cause starting issues.
- Thermal Fuse The thermal fuse is used to completely turn off your dryer in case of extreme heat, and is usually triggered by a buildup or restricted airflow. If it is blown, it will need to be replaced before the dryer will operate.
- Terminal Block The power from the wall outlet to your dryer goes through the terminal block; if the block is burnt or damaged it can cause your dryer to not turn on or function properly.
- Idler Pulley This pulley ensures that the belt fits tightly on the drum and operates smoothly. If your dryer won’t start, it could be that the pulley has malfunctioned and the belt is non-operational.
