Cold Room Temperature Rising — Emergency Diagnosis & Repair

Recognising these signs early can prevent total product loss:

• Controller shows a steady upward trend away from set point
• Alarms triggering as product temperature crosses the HACCP limit
• Compressor cycles but net temperature still increases
• Frost appearing then melting on the evaporator in rapid cycles

Take these steps now, before our technician arrives:

• Record the current temperature and the time it started rising — this helps our tech diagnose faster.
• Keep the door closed to preserve the remaining cold mass inside the room.
• If a defrost cycle is stuck, do not force it — switching the unit off can crack coils.
• Call REYDS immediately; rising temperature means the fault is active and worsening.

Our technicians check each of these in turn to pinpoint the fault:

• Defrost failure — Ice accumulates on the evaporator, insulating it so it can no longer absorb heat from the room.
• Refrigerant leak — Gradual gas loss reduces capacity until the plant can no longer hold set point.
• Door seal failure — Warm, humid air continuously enters, overwhelming the system's cooling capacity.
• Dirty condenser — A fouled condenser raises head pressure, cutting compressor capacity and efficiency.

REYDS logs the temperature trend, identifies the root cause with gauges and a thermal scan, then executes the repair — re-gassing, defrost repair, or seal replacement — and stays until the trend reverses and the room is pulling down again.

Fit a remote temperature alarm with SMS alert. Annual door-seal and defrost-heater checks catch the common culprits early.
