What To Know
- If the meter beeps or displays a low resistance value (typically below 1 ohm), the switch is closed and working properly.
- If the switch is faulty, replacing it is a relatively simple repair that can restore your dryer to working order.
- Can I bypass the start switch on a Whirlpool dryer.
If your Whirlpool dryer is not starting, a faulty start switch could be the culprit. This essential component initiates the drying cycle by sending a signal to the motor. Testing the start switch is crucial to diagnose and resolve the issue. This comprehensive guide will walk you through the steps on how to test a Whirlpool dryer start switch accurately.
Identifying the Start Switch
Locate the start switch on the dryer’s control panel. It is usually a button or knob labeled “Start” or “Cycle Start.”
Safety Precautions
Before proceeding, ensure the dryer is unplugged from the power outlet. Wear appropriate safety gear, such as gloves, to prevent electric shock.
Tools Required
- Multimeter
- Screwdriver
Testing Procedure
1. Continuity Test
- Set the multimeter to the continuity setting.
- Touch one probe to the terminal on the start switch.
- Touch the other probe to the other terminal.
- If the meter beeps or displays a low resistance value (typically below 1 ohm), the switch is closed and working properly.
2. Resistance Test
- Set the multimeter to the resistance setting.
- Touch one probe to each terminal on the start switch.
- If the meter displays a high resistance value (typically over 1 megohm), the switch is open and not working.
Troubleshooting Results
Continuity Test:
- Beep or Low Resistance: The switch is closed and working.
- No Beep or High Resistance: The switch is open and needs to be replaced.
Resistance Test:
- Low Resistance: The switch is closed and working.
- High Resistance: The switch is open and needs to be replaced.
Replacing the Start Switch
If the start switch is faulty, it needs to be replaced.
- Disconnect the dryer from the power outlet.
- Remove the screws holding the control panel in place.
- Locate the start switch and disconnect the wires.
- Install the new start switch and reconnect the wires.
- Reassemble the control panel and reconnect the dryer to the power outlet.
Other Possible Causes of Dryer Not Starting
- Faulty door switch
- Broken belt
- Thermal fuse tripped
- Motor failure
Takeaways
By following these steps, you can accurately test a Whirlpool dryer start switch. If the switch is faulty, replacing it is a relatively simple repair that can restore your dryer to working order.
