Dryer Won't Start
A dryer that will not start at all -- no hum, no lights, no response when you press start -- is almost always a break somewhere in the safety and control circuit rather than a problem with the motor or heater themselves. Those parts never even get a chance to run if the start circuit is not complete.
Work through this circuit from the most likely cause to the least likely. Most "won't start" repairs are inexpensive once the actual cause is confirmed, since the parts involved are small switches and fuses rather than the motor or drum.
If the dryer responds and runs but never produces heat, that is a separate problem -- see Dryer Not Heating instead.
Safety first. Dryers combine household electricity, a spinning drum and motor, and -- on gas models -- a live fuel line.
- Unplug the dryer, or shut off the breaker for a hardwired unit, before removing any panel or touching internal components.
- Gas dryers: shut off the gas supply valve behind the unit before working on it. If you smell gas at any point, leave the area immediately and call your gas utility from outside -- do not flip switches or search for the leak yourself.
- Lint is flammable. A clogged lint trap or exhaust vent is a fire hazard, not just a performance problem -- treat a dryer that runs hot, or a thermal fuse that keeps blowing, as a reason to check the vent, not just replace the part.
- Call a licensed technician if you are not confident identifying or safely accessing a part.
Most Likely Causes
- Door switch — The most common cause. A dryer will not run with the control circuit reading the door as open, even if it is fully closed, once the switch itself fails. Sold as Dryer Door Switch (3406107).
- Door latch/strike hardware — If the physical latch no longer presses the door switch firmly closed, the result looks identical to a failed switch. See Dryer Door Latch Broken.
- Thermal fuse — A blown thermal fuse cuts power to the whole control circuit on many models, not just the heater, so the dryer will not start at all. See Dryer Thermal Fuse Blown.
- Start switch or touchpad — If the console lights up and the door reads as closed but pressing start does nothing, the start circuit itself has failed. See Dryer Start Button Not Responding.
- Power supply — Confirm the outlet or breaker is actually delivering power before assuming a part has failed -- electric dryers use a 240-volt double-pole breaker, so one tripped half can cause partial symptoms rather than a completely dead unit.
The start circuit (door switch, latch, thermal fuse, and start switch) is identical on electric and gas dryers -- both use the same low-voltage control circuit to authorize a cycle before the heating circuit, electric or gas, ever engages.
Diagnostic Order
- Confirm the outlet or breaker has power, and that both halves of a 240-volt breaker are on.
- Open and firmly close the door a few times, listening for the latch to click -- a door that does not latch securely points to the latch hardware rather than the switch.
- Test the door switch for continuity with the door held closed.
- Test the thermal fuse for continuity -- zero continuity means it is blown and is very likely cutting power to the whole control circuit.
- If the door switch and fuse both test fine but pressing start still does nothing, move to the start switch or touchpad.
Working Through It Methodically
Resist the urge to replace parts in a different order than the one above just because a part is cheap or easy to reach. Testing each component with a multimeter before buying anything takes only a few minutes longer than guessing, and it avoids the common outcome of replacing two or three parts in a row before finding the one that was actually at fault. If every part in the start circuit tests normal and the dryer still will not start, the fault is most likely in the control board itself, which is usually the last part checked precisely because it is the most expensive to replace and the least likely single cause.
Check Your Exact Model
Once you have narrowed the cause down to a part type, confirm it against your exact dryer rather than guessing from the brand alone. Use the model and part lookup tool to search by your dryer's full model number, or start from one of these confirmed model pages to see the exact parts list for that unit:

How to Confirm Before You Buy a Part
Before ordering any replacement part, take a minute to confirm fitment -- it is the difference between a repair that works the first time and a part that has to be sent back.
- Find the model/serial plate. On most dryers it is inside the door opening (printed on the frame you see when the door is open), behind the lint trap housing, or on the back panel near the power cord. See how to find your model number if you cannot locate it.
- Read the full model number exactly as printed, including every letter and dash -- manufacturers reuse near-identical model numbers across different production runs that take different parts.
- Verify the part fits that exact model using the model and part lookup tool before you buy, rather than assuming a part that looks the same will fit.
The full model number matters more than the brand and appliance type alone. Manufacturers commonly reuse one body design across many model numbers over several years, changing the exact door switch, control board, or heating circuit partway through the run -- so two dryers that look identical side by side can still take different parts.
