The door switch is perhaps the most obvious culprit for a dryer not starting. If the dryer can't detect that the door is securely closed, it simply won't do anything. Try using a multimeter to detect current continuity. With the door closed and locked, you should get a reading of zero ohms. If not, the door switch apparatus may be worn or damaged. Time for a replacement part.
If your dryer is showing no signs of life, it's likely that your laundry routine has been thrown off course. So, don’t wait around: let's find out what could be happening. First, open the dryer door. If the light turns on, you can rule out a power issue. If it doesn't, check the power supply and reset the breaker. Still nothing? It's time to explore other potential causes.
1. DOOR SWITCH
2. START SWITCH
The power supply is fine, the lights are on, and the door switch appears to be okay. But nothing happens when you press the start switch. The switch itself could be to blame. Test it with a multimeter (or get a specialist to do it). If there's no continuity, your dryer could be repaired with a simple replacement start switch.
3. THERMAL FUSE
Most dryers are equipped with thermal fuses as a safety measure. These fuses blow when the dryer reaches unsafe temperatures. Afterwards, they have to be replaced before the dryer will be operable again. A blown fuse will not have any continuity when tested with a multimeter.
Remember that a thermal fuse probably blew because a blocked exhaust vent made it impossible for the dryer to release heat. Make sure you inspect all vents to ensure they're completely clear of lint and any other debris.
4. DRIVE MOTOR
The drive motor turns the drum as well as the blower wheel. If the dryer is humming but not actually working, it's time to check the drive motor. First, inspect the drive belt to ensure it hasn't snapped, worn down, or simply slipped. If it seems to be intact, you may have a defective drive motor that needs to be replaced.
5. CONTROL BOARD
Main control boards rarely falter, but it is a possibility. It's tricky to conduct a DIY test to see if the board is causing the problem, but you may see signs of burning or scorching if something is amiss. The only remedy is to replace the board, which will likely require the attention of a trained technician.
