Cold Room Compressor Repairs Johannesburg
The compressor is the heart of the refrigeration system. We diagnose whether a compressor can be repaired or must be replaced — and we don't replace compressors that only need a contactor, a capacitor or a refrigerant top-up.
- [01]Compressor not starting
- [02]Compressor short-cycling
- [03]Tripping on thermal overload
- [04]Unusual knocking or vibration
- [01]Contactor failure
- [02]Capacitor failure
- [03]Refrigerant floodback
- [04]Electrical fault
- [05]Mechanical wear
We test electrical continuity, insulation, run and start capacitors, contactor integrity and system pressures before condemning a compressor.
Where a compressor is salvageable we repair the cause; where it must be replaced we size and commission the replacement correctly.
My compressor isn't starting — is it dead?
Not necessarily. Many 'dead' compressors are actually a failed contactor or capacitor — we test before replacing.
Can you replace a compressor same day?
Common compressor sizes are stocked; larger units may require ordering, with temporary cooling provided.
Why did my compressor fail?
We diagnose the root cause — often an underlying refrigerant or electrical fault — so the new compressor is not damaged the same way.
