Avoid breakdowns before they happen with this inside look from BM Refrigeration.
Whether you run a busy restaurant, a high-volume dark kitchen, or a medical storage site, one thing is clear: your cold room must work all the time. At BM Refrigeration, we attend many emergency call-outs. A lot of these problems could be avoided with simple checks and regular servicing.
In this guide, we explain the five cold room problems we see most often, and the easy ways to help prevent them. This can save you time, money, and stress.
1. Worn or Cracked Door Seals
The Problem:
Door seals (also called gaskets) stop warm air from getting into the cold room. When seals are torn, cracked, or not sitting right, warm air leaks in. That makes the system work harder and can cause:
- Ice buildup on coils
- Higher power bills
- Uneven temperatures
- Spoiled or unsafe stock
How to Prevent It:
- Check door seals every week for cracks, gaps, or hard spots
- Keep doors closed as much as possible
- Replace worn seals straight away
BM Tip: If your cold room has lots of traffic, install plastic strip curtains to help keep cold air inside.
2. Blocked or Dirty Condenser Coils
The Problem:
Condenser coils release heat from the system. If the coils get covered in dust or grease, the heat can’t escape well. This can lead to:
- Overheating
- Longer run times
- Higher electricity costs
- Shorter equipment life
How to Prevent It:
- Clean coils every 3 months
- Use a soft brush or vacuum to remove dust
- In kitchens (greasy areas), clean monthly
Warning Sign: Your power bill jumps suddenly, or the cold room feels warmer than normal.
3. Faulty or Frozen Evaporator Fans
The Problem:
Evaporator fans move cold air around the room. If a fan freezes up, rusts, or fails, air won’t move properly. This can cause warm spots, frozen spots, and stock damage.
How to Prevent It:
- Book regular servicing so fans can be checked and cleaned
- Make sure defrost is working properly
- Listen for strange noises like grinding, rattling, or humming
BM Tip: If a fan sounds different, don’t ignore it. A small fan problem can quickly turn into a full breakdown.
4. Refrigerant Leaks
The Problem:
Refrigerant is what helps the system remove heat and cool the room. If there’s a leak, the system can’t cool properly. The compressor runs longer, temperatures rise, and food safety can be at risk. Adding more gas without fixing the leak is only a short-term patch.
How to Prevent It:
- Have a licensed technician check for leaks during servicing
- Watch for ice build-up in unusual places
- Look for slower cooling or unstable temperatures
Warning Signs:
- Ice forming where it shouldn’t
- The compressor running almost all the time
- The room struggling to reach the set temperature
5. Thermostat or Sensor Malfunctions
The Problem:
Thermostats and sensors tell the system when to cool and when to stop. If they fail, the cold room may run too cold, not cold enough, or switch on and off at the wrong times. This can risk your stock and put extra strain on your equipment.
How to Prevent It:
- Test thermostats and sensors during routine checks
- Calibrate or replace faulty sensors
- Run test cycles before busy seasons
BM Tip: A temperature logger can alert you early if the temperature moves outside the safe range.
