Freezer Room Not Freezing in Cason
Freezer Room Not Freezing is one of the faults we attend most often in Cason. It is a symptom rather than a diagnosis — several very different failures produce the same behaviour, which is why measurement matters more than guesswork.
Below are the causes we actually find on site, the process we use to separate them, and how quickly we can get to you. If stock, trading or comfort is at risk, phone 069 268 0988 rather than waiting for a form reply.
[probable_causes]
What we typically find
- Low-temperature plant undersized or losing capacity
- Electric defrost heaters failed, leaving a blocked coil
- Refrigerant undercharge
- Damaged floor or panel insulation adding load
- Door heater failure icing the entrance
[diagnostic_protocol]
How we isolate the fault
- Verify pull-down performance from ambient to set point under load
- Check electric defrost heaters, termination probe and drain line trace heating
- Inspect for ice on the evaporator, ceiling and door frame — each points to a different fault
- Measure superheat and subcooling to confirm charge and expansion valve operation
- Check compressor oil level, crankcase heater and safety controls
- Test door heaters, closers, seals and floor build-up for frost heave
