If the lights are working in your dryer, but it won't turn on, there are a few potential reasons for this issue. Some common causes include:
Power Supply Issues: The dryer may not be receiving power properly. Check if the circuit breaker or fuse that controls the dryer's electrical circuit has tripped or blown. If it has, reset the breaker or replace the fuse. Also, ensure that the dryer's power cord is properly plugged into the electrical outlet.
Door Switch Problem: Most dryers have a door switch that prevents them from starting if the door is not properly closed. If the door switch is faulty or not engaging properly, the dryer won't turn on. Check the door latch and the door switch to see if they are functioning correctly.
Thermal Fuse Tripped: The thermal fuse is a safety feature that prevents the dryer from overheating. If the thermal fuse has tripped due to excessive heat, the dryer won't turn on. You may need to replace the thermal fuse.
Broken Belt: Some dryers have a belt that turns the drum. If the belt is broken or has come off the pulley, the dryer won't be able to start. You may need to replace the belt.
Defective Start Switch: The start switch on the dryer can become defective over time, preventing the dryer from turning on. If the switch doesn't complete the electrical circuit, the dryer won't start.
Faulty Control Board: Modern dryers often have electronic control boards that can fail due to power surges or other issues. If the control board is faulty, it may not send the signal to start the dryer.
Motor Issues: If the dryer motor is faulty or seized, the dryer won't start. You can try manually turning the drum to see if the motor is stuck.
It's essential to exercise caution when troubleshooting electrical appliances like dryers. If you are unsure about the issue or how to fix it, it's best to consult a professional appliance repair technician to diagnose and resolve the problem safely.
