Cold Room Not Holding Temperature
For food businesses, a cold room drifting above temperature isn't just an inconvenience, it's a stock safety and due diligence issue, which is why we treat these calls with urgency. The good news is that the causes tend to fall into a fairly small number of categories, and a quick visual check can often narrow things down before an engineer even arrives.
Because these units run continuously under commercial loads, small issues that would go unnoticed in a domestic fridge tend to show up faster and more obviously here.
Common causes, roughly in order
- Door seals worn or damaged, letting warm air in constantly
- Evaporator coil iced up, restricting airflow inside the room
- Condenser unit outside or on the roof blocked by debris or grease, especially near kitchen extraction
- Refrigerant leak reducing the system's cooling capacity
- Door left ajar or propped open during busy service periods
Checks staff can safely do immediately
Check the door closes fully and the seal isn't torn, perished, or has food debris preventing a good close. Look at the evaporator unit inside the room for visible ice build-up, and check the outdoor or roof-mounted condenser isn't smothered in leaves, grease-laden air deposits, or blocked by stored items placed too close.
If stock temperature is a live concern, move perishable items to a working fridge or freezer as a precaution while the fault is assessed, and log the temperature readings and time for your food safety records.
Why this needs a same-day response
Beyond stock loss, most food safety management systems require documented corrective action when a cold room runs out of range, so a fast, properly recorded engineer visit matters for compliance as well as the immediate fix. Diagnosing whether the fault is refrigerant, electrical, or mechanical needs gauges and load testing that isn't something kitchen staff can or should attempt.
What we do on-site
We check door seals, defrost cycle operation, evaporator and condenser condition, and refrigerant pressures against the system's design specification. Where we find the room is running but struggling under load, rather than fully broken, we'll explain what's driving that so you can judge whether stock is at risk while any parts are sourced.
Reducing the risk of recurrence
- Include door seal condition in daily opening checks
- Keep condenser units clear of grease build-up and debris, particularly near kitchen extraction outlets
- Book scheduled maintenance visits rather than waiting for a breakdown, particularly ahead of summer
FAQs
Common questions
How quickly can you attend a cold room breakdown?
We prioritise commercial refrigeration breakdowns given the stock and food safety implications, and offer emergency cover outside normal hours for urgent cases.
Should I move stock while waiting for an engineer?
Yes, if you have spare cold storage capacity, moving perishable stock is a sensible precaution while the fault is assessed.
Can worn door seals really cause this much of a problem?
Yes, a poor seal lets in a constant stream of warm, humid air that the refrigeration system then has to fight continuously, which is a significant extra load.
Do you offer maintenance contracts for commercial refrigeration?
Yes, scheduled maintenance is available and is generally the most cost-effective way to avoid unplanned breakdowns and stock loss.
