Fridge Controller Replaced in Goulburn
Job summary

Customer report
The unit at Subway in Goulburn was reported as a breakdown and was observed with the compressor running continuously. The fridge temperature was recorded at -8.0c, and the thermostat was checked against the temperature gauge during assessment. The controller was then isolated for testing, and the unit remained in the fault condition before replacement work proceeded.
Diagnosis & technical assessment
The technician assessed the under-bench fridge TM104121 after the breakdown report and observed the compressor running continuously. The fridge temperature was recorded at -8.0c. The thermostat was checked against the temperature gauge and was found to be running true to that gauge. The technician turned the fridge off at the controller, but the compressor continued to run. The controller wiring was inspected and appeared sound. On the basis of those checks, The technician suspected a faulty Carel controller and proceeded with replacement.

Solutions delivered
Ethan attended site and installed a new Carel Ezy controller from stock for the under-bench fridge. The existing controller was replaced, the wiring was completed, and the setup was carried out to suit the unit. The replacement choice followed the assessment that the controller was the most likely fault source, with the wiring visually checked and no other fault detail recorded before replacement. The controller and system operation were then tested after installation.

Repair vs replacement
In refrigeration controller faults, replacement is generally used when the control unit is the most likely failure point and the surrounding wiring and components appear sound. A repair may be suitable where a specific wiring, sensor, or connection fault can be isolated and corrected. In this job, the thermostat check, continuous compressor operation, and controller isolation supported replacement of the controller rather than a separate repair to the fridge system.
If a heating, cooling or refrigeration system shows signs of a fault, such as burning smells, water leaks or tripping power, switch it off where safe and contact a licensed technician.
