How to Fix / Troubleshooting
Safety: Do not repeatedly reset a breaker that trips immediately; this indicates a potentially dangerous fault. Unplug the unit before inspection.
Steps:
- Check circuit: Ensure the air conditioner is on a dedicated circuit with the correct amperage rating per NewAir specifications.
- Inspect cord and plug: Look for burn marks, melted plastic, or exposed wires. Replace the power cord assembly if damaged.
- Isolate components: With power disconnected, test resistance of the compressor, fan motors, and capacitor for shorts to ground.
- Replace failed parts: Replace any motor or compressor that shows continuity to ground. Replace bulged or shorted run capacitors.
- Professional help: If you cannot identify the fault, contact a qualified technician to avoid fire or shock hazards.
