If your Whirlpool dryer is not starting when you press the start button, there could be a few possible reasons for this issue. Here are some troubleshooting steps you can try:
Check the power supply: Ensure that the dryer is properly plugged into a functioning power outlet. Check the circuit breaker or fuse box to see if a circuit breaker has tripped or a fuse has blown. Reset or replace any necessary breakers or fuses.
Door switch: The dryer's door switch may not be engaging properly. Open the dryer door and close it firmly to make sure the door switch is activated. If the switch is faulty or not functioning correctly, it may need to be replaced.
Check the control panel: Inspect the control panel for any error codes or indicators that could indicate a problem. Consult the dryer's manual for specific troubleshooting steps related to error codes or control panel issues.
Thermal fuse: The thermal fuse is a safety device that can interrupt power to the dryer if it overheats. If the thermal fuse is blown, the dryer may not start. You can use a multimeter to test the thermal fuse for continuity. If it's faulty, it will need to be replaced.
Start switch or control board: The start switch or the control board could be faulty. These components may require professional diagnosis and replacement, so it's advisable to contact a Whirlpool service technician or a qualified appliance repair professional for assistance.
Remember to always prioritize your safety when troubleshooting or working with electrical appliances. If you're unsure or uncomfortable with performing any of the steps, it's best to seek professional help to avoid any potential hazards.
