How to Fix / Troubleshooting

Safety first: Unplug and allow the unit to cool completely.

Confirm symptom: Run a short cycle and feel for any warmth near the exhaust. If completely cold, proceed with heater checks.
Access heater terminals: Remove the top cover to expose the heating element and its wiring.
Check connections: Tighten any loose spade connectors and look for discoloration or burning at the terminals.
Test heater and fuse: Disconnect one heater lead and measure resistance across the element. Also locate and test any inline thermal fuse in series with the heater. Replace any open component.
Inspect control board: If heater and fuse are good, inspect the heater relay/triac on the PCB for burn marks. Replace the main control PCB if the switching device has failed.

Warning: Do not attempt to repair a cracked or broken heating element; always replace the entire assembly.
