🛠️ How to Fix Whirlpool Dryer L2 Error
- Reset the Breaker: Flip the dryer breaker OFF and then back ON firmly.
- Inspect the Plug: Pull the plug out and look for black scorch marks. If it’s burnt, replace the cord immediately.
- Check Terminal Block: Remove the small cover on the back of the dryer where the cord connects. Tighten any loose screws (The “Wiggle Test” for power!).
- Test Voltage: Use your multimeter to ensure you have 120V from each side to ground, and 240V across both hot wires.
🤔 Steve’s Quick Troubleshooting FAQ
Q: Why does the dryer run but not heat up during an L2 error?
Steve: Electric dryers use 120V to run the motor, lights, and timer, but they need the full 240V to power the heating element. When you get an L2, you’re missing one of the 120V “legs,” so the motor works but the heat doesn’t!
Q: I reset the breaker, but L2 keeps coming back. Is my main board bad?
Steve: Not always. Check the Terminal Block on the back of the machine. If the wires are loose or the plastic is melted, it creates high resistance that triggers the L2 code. Perform a “Wiggle Test” on those power connections first!
