Commercial Refrigeration Malfunctions
The Gloucestershire Business Owner’s Guide to Staying Chill
If you run a restaurant, cafe, butchers, or even a florist in Gloucestershire, your refrigeration systems are the unsung heroes of your business. You probably don’t think about them much until something stops working and you’re suddenly looking at thousands in spoiled stock and lost revenue.
At TK Refrigeration, we’ve been called in after emergency breakdowns far too often—many of which could have been prevented with simple checks or timely servicing. So let’s clear up some common misconceptions and dig into what actually causes commercial refrigeration systems to fail, and how you can stay ahead of it. Explore our full range of refrigeration products to find reliable solutions for your business.
1. “It Just Stopped Working” – Rarely the Full Story
Most refrigeration breakdowns don’t happen overnight. It’s usually a build-up of minor issues:
- Dirty condenser coils
- Refrigerant leaks
- Faulty thermostats
- Clogged drain lines
All of these can slowly reduce your system’s efficiency until boom it shuts down when you need it most.
2. Poor Ventilation Around the Unit
One of the most common issues we come across though it often flies under the radar is restricted airflow around commercial fridges and freezers. This happens a lot in compact kitchen setups. When the system can’t release heat effectively, the compressor ends up overworking itself and, eventually, gives out.
Quick Fix:
Keep at least 5–10 cm of clearance around ventilation areas and avoid stacking boxes or bins near the back.
3. Dirty Coils = Higher Bills + Shorter Lifespan
Dust, grease, and grime on evaporator or condenser coils force your system to overwork. It’s like trying to cool your shop while all the windows are open. The system just can’t do its job properly.
Pro Tip:
Schedule coil cleaning at least twice a year more if your space generates grease like kitchens or bakeries.
4. Lack of Preventive Maintenance
Let’s be honest: maintenance is often the last thing on the to-do list until something breaks. But like cars, refrigeration systems last much longer and perform more efficiently when serviced regularly.
At TK Refrigeration, we recommend:
- Quarterly service for busy kitchens
- Biannual checks for lower-use environments
- Temperature calibration and leak checks included every time
5. Door Seals That Don’t Seal
If your door gasket is torn, loose, or dirty, cold air escapes constantly. That means your fridge is running longer and harder to maintain temperature which increases wear and raises your energy bill.
Quick Test:
Close a £5 note in the door. If it pulls out easily, your seal probably isn’t tight enough.
6. Power Surges and Unstable Electrical Supply
Power issues, especially in older buildings in towns like Stroud or Cirencester, can quietly damage components over time. Surges can fry compressors, sensors, and circuit boards.
Protect your system:
Install surge protectors and have a commercial electrician inspect your supply if you’ve experienced flickering or outages.
7. Human Error
Staff accidentally leaving doors open, overloading storage, or placing hot food inside can cause temporary malfunctions or long-term damage.
Simple fixes:
- Train staff on best refrigeration practices.
- Use door alarms for units that get heavy use.
- Let cooked items cool before storing them.

FAQs
- How often should I service my commercial refrigeration unit?
For most commercial setups, at least every 6 months. Busier environments like restaurant kitchens benefit from quarterly checks. - Can I clean condenser coils myself?
You can, but professional cleaning ensures no parts get damaged and proper inspection is done at the same time. - What’s the cost of ignoring a minor issue?
A small refrigerant leak might cost £100 to fix today or lead to a £1,000 compressor replacement if ignored.
