Cold Room Not Holding Temperature? 5 Causes & Quick Fixes
A walk-in running at 8 °C can spoil thousands in stock and trigger HACCP breaches. Before you panic, run through these five checks—then call
1300 227 600 if temps stay high.
1. Blocked Evaporator Coil
Ice blankets airflow and the temperature climbs. Defrost manually, check heaters and fans.
2. Door Gasket Gaps or Damaged Sweeps
Warm air leaks overload the compressor. Inspect seals; replace damaged gaskets within 24 hours.
3. High Ambient Airflow Across the Condenser
Back-of-house temperatures over 32 °C reduce cooling capacity 12 %. Improve ventilation or relocate the unit.
4. Faulty Expansion Valve or Refrigerant Loss
Sweating suction line + high super-heat means a pro needs to test for leaks and balance charge.
5. Poor Stock Loading Practices
Boxes against vents choke circulation. Maintain a 100 mm gap around the evaporator.
