Possible Causes

Blown internal fuse on main control board, Faulty power cord or plug, Open thermal fuse on compressor or transformer, Failed main control board

How to Fix / Troubleshooting

Safety first: Ensure the outlet is not live before touching bare wires. Unplug the unit before opening any panels.

Steps to diagnose no power:

  • Check outlet: Test the wall outlet with another appliance or a voltage tester. Reset any tripped breakers or GFCI outlets.
  • Inspect power cord: Look for cuts, burns, or kinks. If damaged, replace the power cord assembly.
  • Access control board: Remove the control panel cover and locate the onboard fuse. Test it with a multimeter for continuity. Replace with the same rating if blown and investigate for shorts.
  • Check thermal fuses: Some models have thermal fuses or cutouts on the transformer or compressor wiring. Test for continuity and replace if open.
  • Replace main control board: If power is present at the board input but no LEDs or display light, the main PCB is likely defective and should be replaced.

Warning: If fuses blow repeatedly, there may be a shorted component; do not keep replacing fuses without finding the root cause.
