How to Fix / Troubleshooting
Safety first: Unplug the unit before inspection. If you smell burning or see melted plastic, do not attempt further use.
- Step 1 – Check outlet and breaker: Test the outlet with another appliance. Reset any tripped breakers or GFCI outlets.
- Step 2 – Inspect power cord: Look for cuts, frays, or crushed sections. Replace the power cord set if damaged.
- Step 3 – Internal fuse: Remove the housing and locate any inline fuse or PCB-mounted fuse on the main control board. Test for continuity and replace with the same rating if blown.
- Step 4 – Check AC connections: Ensure the line and neutral wires are firmly attached to the board and any line filter.
- Step 5 – Replace control board: If the fuse is good and power is reaching the board but there is no display or response, replace the main control board assembly.
