How to Fix / Troubleshooting
Safety first: Turn off the breaker before inspecting the terminal block.
Steps:
- Check breaker: Locate the dryer breaker (usually a double 30A). Turn it fully off, then back on.
- Inspect cord and terminal block: Unplug the dryer. Remove the terminal block cover and inspect for burned or loose connections. Tighten screws and replace any burned lugs or wires.
- Verify outlet (with electrician if needed): Ensure 240V is present between the two hot legs and 120V from each hot to neutral/ground.
- Replace cord if damaged: Install a new 3- or 4-wire cord as required by your installation.
