How to Fix / Troubleshooting
Safety first: Turn off power at the breaker before inspecting electrical connections.
Flickering indicates voltage instability under load.
- Check terminal block: Inspect and tighten all connections where the power cord attaches to the dryer.
- Inspect power cord: Replace if there are signs of overheating or damage.
- Dedicated circuit: Ensure the dryer is on a dedicated circuit and not sharing with other high-draw appliances.
- Consult an electrician: If house wiring is undersized or very long, an electrician should evaluate and correct the supply.
