A malfunctioning start switch can prevent your Whirlpool dryer from starting up, leaving you with a pile of wet laundry. Testing the start switch is a crucial step in diagnosing and resolving this issue. Here’s a detailed guide to help you test the Whirlpool dryer start switch:
Required Tools
- Multimeter
- Screwdriver
Safety Precautions
Before you begin, ensure that the dryer is unplugged from the power outlet for safety.
Locating the Start Switch
The start switch is typically located on the control panel of the dryer. It’s usually a button or a knob that you press or turn to start the drying cycle.
Disassembling the Control Panel
To access the start switch, you need to disassemble the control panel. This involves removing the screws that hold the panel in place.
Identifying the Start Switch Terminals
Once the control panel is removed, you can identify the start switch terminals. These terminals are usually labeled “L1,” “L2,” and “COM.”
Testing the Start Switch with a Multimeter
Step 1: Set Multimeter to Ohms Mode
Set your multimeter to the ohms mode.
Step 2: Test for Continuity
Connect one probe of the multimeter to the “COM” terminal and the other probe to either the “L1” or “L2” terminal. If the switch is working correctly, the multimeter should display a reading of 0 ohms.
Step 3: Test for Open Circuit
Press the start switch and hold it in the “on” position. The multimeter reading should now be infinity (open circuit).
Step 4: Repeat for Other Terminal
Repeat steps 2 and 3 for the other terminal.
Troubleshooting a Faulty Start Switch
If the start switch fails the continuity test, it is likely faulty and needs to be replaced.
Replacing the Start Switch
Step 1: Disconnect Wires
Disconnect the wires from the faulty start switch.
Step 2: Remove Old Switch
Unscrew the old start switch and remove it from the control panel.
Step 3: Install New Switch
Place the new start switch in the control panel and secure it with screws.
Step 4: Reconnect Wires
Reconnect the wires to the new start switch.
Step 5: Reassemble Control Panel
Reassemble the control panel and secure it with screws.
Conclusion
Testing and troubleshooting the Whirlpool dryer start switch is a straightforward process that can be completed with basic tools. By following these steps, you can diagnose and resolve the issue quickly and get your dryer back up and running efficiently.
