How to Fix / Troubleshooting
Safety first: Do not repeatedly reset a breaker that trips immediately; this indicates a serious fault.
- Step 1 – Inspect power cord and plug: Look for visible damage, burns, or melted areas. Replace if damaged.
- Step 2 – Try a different circuit: Plug portable units into a different dedicated circuit to rule out other loads causing overload.
- Step 3 – Listen for fault timing: Note whether the breaker trips immediately on power-up, when the compressor starts, or randomly. This helps identify the faulty component.
- Step 4 – Professional testing: A technician should measure insulation resistance of the compressor and motors and inspect the PCB for shorts. Replace the defective component.
