How to Fix / Troubleshooting
Safety first: Turn off the breaker and unplug the unit before any inspection. If you are not experienced with electrical testing, contact a qualified technician.
Diagnostic steps:
- Inspect cord and plug: Look for burn marks, melted plastic, or cuts. Replace the cord set if damaged.
- Isolate components: With the unit unplugged, disconnect compressor, pumps, and fans one at a time, then power up to see if the breaker still trips (only if you are qualified to do so).
- Test compressor: Measure resistance between compressor terminals and from each terminal to ground. Any short to ground indicates a failed compressor.
- Check motors: Test fan and pump motors for shorts or very low resistance. Replace any suspect motors.
