Dryer Won't Start? All the Easy Fixes You Need to Know
When you have a wet pile of clean clothes fresh from the washing machine, all you want to do is get them dry quickly. If nothing happens when you push the button to start the dry cycle, there are several potential issues that could be keeping your dryer from functioning properly. If the door is shut tightly and it’s still not working, try one of these fixes from our friends at Sears Parts Direct.
Replace the Door Switch
The dryer door has a switch that determines whether the door is closed and ready for the dry cycle to begin. If the door switch senses that the dryer door is open, it will be unable to start. If the dryer reads that the door is open when it is tightly shut, you need to replace the door switch.

Replace the Push-to-Start Switch
Some dryers have controls that are mechanical instead of electronic. If you have such a dryer, the push-to-start button begins the drying cycle when the button is pressed and released by initiating a voltage path through the drive motor. If this push-to-start switch is damaged or defective, it may not complete the voltage path, and the dryer may not begin.

Replace the Thermal Fuse
The thermal fuse is used to detect the temperature of air venting from the dryer outward. If the air becomes too hot, the thermal fuse will trip and shut off the dryer if it is electric. This can happen if the vent tube is clogged or kinked or if the exterior damper is shut. If you have a gas dryer, it will still run with a tripped thermal fuse but it will not heat. If it trips, it will not reset when the dryer cools, so it must be replaced.

Replace the Dryer Timer
The dryer timer allows you to set a specified drying time for your clothes. It includes a small motor that advances the timer that opens and closes small electrical contacts to control various components of the dryer throughout the cycle. If the timer won’t advance or the contacts aren’t functioning properly, this could be preventing your dryer from starting or heating.

Repair or Replace the Electronic Control Board
The electronic control board is in charge of controlling timing and execution of various dryer components throughout the drying cycle. If the board itself is damaged, it must be replaced. If it’s an issue of wiring connections, these can often be repaired. It can be hard to determine whether the control board is damaged, so it’s recommended that you have a service technician run diagnostics before you replace it.

Repair or Replace the Drive Motor
The drive motor in your dryer is responsible for rotating the motor shaft that works through the dryer’s internal system to eventually turn the drum. On most dryer models, the drive motor also rotates the blower fan blade. If the drive motor doesn’t run when electricity is applied to it, it must be replaced.

Replace the Drive Belt
The belt of the dryer could be broken or damaged, which will prevent your dryer from turning on. To check it, unplug the dryer and remove the top panel. If it is broken or damaged, it must be replaced.

Replace the Door Catch
When the dryer door is shut, a spring-loaded door catch grips the door strike to hold its position. Tension from the door catch keeps the door from opening during a dry cycle. If you examine the door and find that the strike is intact but the door won’t latch shut, you need to replace the door catch to keep the door shut so it can run properly.

Replace the Door Strike
The dryer door strike is part of the latch assembly that keeps the door closed during a dry cycle. It can either be attached to the front panel of the dryer or to the door itself. When you close the dryer door, the door strike is pushed into the door catch mounted across from it to hold the door closed. If the door strike is damaged, the door catch may be unable to grip it and the door will not stay closed. To fix this, replace the door strike so your dryer door can hold shut.

Replace the Motor Relay
Some dryer models include an electrically operated switch called a motor relay. If the voltage supply stops, the motor relay then stops the drive motor and prevents the dryer from running. This will cause the dryer to stop running as soon as the start button is released.

Replace the Power Cord
If your dryer’s power cord is damaged or dysfunctional, it could be preventing your dryer from drawing power. Check for signs of overheated, loose or shorted wires or melted insulation. If there are visible signs of damage, replace your power cord.
