Heat Pump Compressor Fault in Weltevreden Park
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 Weltevreden Park.
This fault is normally treated as same-day work because the site has effectively lost hot water, steam or safe operation.
Weltevreden Park sits within the Randburg belt, with larger stands, long hot water runs and frequent pool heating. Static pressure and dead-leg length are checked as part of any hot water complaint here. Sites with long, poorly insulated pipework lose more heat in distribution than most owners expect, which reads as a capacity problem at the outlet.

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.
