Every breakdown has a root cause
Select a fault node to see how Reyds diagnoses and repairs it across Wonderboom and Pretoria North. We don't treat symptoms — we trace the fault to its source.
Compressor Failures
The heart of the system — diagnosed, repaired or replaced
A compressor failure is the most consequential breakdown a commercial cold room can suffer. In Wonderboom, where supermarkets, butcheries and mortuaries depend on continuous cooling, a failed semi-hermetic or scroll compressor must be diagnosed correctly — not just swapped — or the replacement will fail again within weeks.
- ▸ Compressor not starting, humming or tripping on overload
- ▸ Burnt or contaminated oil, acid test positive
- ▸ Loss of cooling capacity with compressor still running
Commercial refrigeration, specified
Six fault categories. One engineering standard. Every Reyds repair is documented, certified and logged — built for supermarkets, butcheries, mortuaries, laboratories and cold-chain operators.
Walk-In Cold Rooms
Structural thermal integrity for commercial storage
Walk-in cold rooms are the backbone of food retail, hospitality and pharmaceutical storage in Wonderboom. A single seal failure, door-gasket leak or evaporator coil fault can collapse your holding temperature inside an hour and put an entire stock line at risk.
Freezer Rooms
Sub-zero holding for frozen and deep-freeze stock
Freezer rooms operating at -18°C and below are unforgiving. When a defrost system fails in a Wonderboom freezer room, ice bridges the coil within hours and the room temperature climbs past the critical -15°C safety threshold where product integrity is lost.
Compressor Failures
The heart of the system — diagnosed, repaired or replaced
A compressor failure is the most consequential breakdown a commercial cold room can suffer. In Wonderboom, where supermarkets, butcheries and mortuaries depend on continuous cooling, a failed semi-hermetic or scroll compressor must be diagnosed correctly — not just swapped — or the replacement will fail again within weeks.
Temperature Faults
When the setpoint drifts, the clock is ticking
Temperature faults are the silent killer of commercial refrigeration in Wonderboom. The room is still running, the compressor still cycles — but the product is slowly warming past its safe holding range. Accurate diagnosis separates a five-minute sensor fix from a full refrigerant recharge.
Refrigerant Leaks
Find it, fix it, certify it — not just top it up
Refrigerant leaks in Wonderboom cold rooms are often treated as a 'top-up' problem. They are not. Every recharge that isn't paired with a proper leak search is a slow loss of capacity, rising energy cost and eventual compressor failure. Reyds finds the leak, repairs it, and certifies the system tight before recharging.
Electrical Faults
Control circuits, contactors and power supply diagnosis
Electrical faults are the most under-diagnosed cause of cold room breakdowns in Wonderboom. A pitted contactor, a failed defrost relay or a voltage imbalance on the three-phase supply can mimic a refrigeration fault — and replacing a compressor for an electrical problem is an expensive mistake.
