Heat Pump Compressor Fault in Paulshof Ext

The compressor will not start, hums and trips, or cuts out on overload. This page covers how we diagnose and repair it on heat pumps in Paulshof Ext.

This fault is normally treated as same-day work because the site has effectively lost hot water, steam or safe operation.

Paulshof Ext is an extension of Fourways with a mix of original and renovated housing, so geyser positions, pressure control and pipework standards vary stand to stand. Where a site runs on borehole water, hardness and iron content shorten service intervals considerably and are worth testing before setting a maintenance plan.

FAQs

Frequently asked questions

What causes heat pump compressor fault?

The usual causes are failed start or run capacitor, seized compressor, failed contactor or welded contacts, overload protector tripping on high discharge temperature. Which one it is can only be confirmed by measurement, not by symptom alone.

How do you diagnose it?

Capacitor microfarad test; Winding resistance and insulation test; Contactor inspection under load; Supply voltage and phase balance measurement. The readings are recorded so the repair decision is based on data.

Can I keep using the system in the meantime?

No — isolate the plant and call 069 268 0988. Running it in this condition risks further damage or an unsafe situation.
