FAQs

Frequently asked questions

What causes heat pump keeps tripping the breaker?

The usual causes are failed element or moisture ingress causing earth leakage, compressor winding breakdown to earth, undersized or degraded breaker, damaged supply cable or corroded terminals. Which one it is can only be confirmed by measurement, not by symptom alone.

How do you diagnose it?

Insulation resistance test on compressor and element; Earth leakage measurement with the unit isolated stage by stage; Thermal inspection of terminals and contactors; Start current measurement. The readings are recorded so the repair decision is based on data.
