How Our Diagnosis & Repair Works
Probe Resistance & Relay Diagnosis
We compare sensor probe resistance against calibrated reference thermometers and test controller output relays.
Sensor or Controller Replacement
We install genuine commercial controllers and sealed moisture-proof probes suited to chilled or sub-zero duty.
Parameter Programming & Calibration
We configure set point, differential, compressor anti-short-cycle delay, defrost termination and alarm limits.
Precision Control for Food Safety & Compressor Protection
Modern walk-in chillers and freezers rely on microprocessor controllers to govern cooling cut-in/cut-out, compressor anti-short-cycle delays, defrost termination, evaporator fan delays and high-temperature alarms.
When an unsealed sensor probe absorbs moisture or an internal relay contact welds shut, your cold room either loses cooling or over-freezes delicate chilled stock. We carry commercial universal and OEM controllers and replacement probes to restore accurate, dependable control on the first visit whenever possible.
