🧊 7 Quick Tips for Troubleshooting Your Commercial Refrigerator (Plus a Bonus!)
Maintaining a commercial refrigerator can feel like walking a tightrope—especially when it decides to misbehave right before a busy service. Whether you’re a seasoned restaurateur or new to food service, knowing how to troubleshoot common issues can save you time, money, and stress.
Here are 7 essential tips to help you stay cool—literally and figuratively.
🔌 1. Check the Power Supply
It might seem obvious, but it’s one of the most overlooked issues.
- Ensure the fridge is plugged in
- Check the circuit breaker
- Try a different appliance in the same outlet
🔍 Also, inspect for loose or damaged cords and power switches that may have been accidentally flipped off.
🌡️ 2. Inspect the Thermostat Settings
Incorrect thermostat settings can lead to performance issues.
- Ensure the temperature is set between 1.7°C and 3.3°C
- Look for signs of tampering or accidental changes
- If temperature doesn’t stabilize, the thermostat may be faulty
🛠 A professional technician can confirm and replace the thermostat if needed.
🧽 3. Clean the Condenser Coils
Dirty coils = poor performance and higher energy bills.
- Unplug the unit
- Use a coil brush or vacuum
- Clean every 3–6 months
🧊 Clean coils help your fridge cool faster and last longer.

🚪 4. Examine the Door Seals (Gaskets)
Damaged gaskets let cold air escape, overworking your fridge.
- Test with a paper slip: if it pulls out easily, the seal is weak
- Look for cracks, tears, or wear
- Replace damaged seals ASAP
🧼 Clean seals regularly to prevent grime buildup and maintain suction.

🌬️ 5. Monitor the Evaporator Fan
Uneven cooling? The evaporator fan could be to blame.
- Listen for unusual noises
- Check for obstructions or damage to the blades
- Inspect the fan motor if it doesn’t run properly
🧰 Always unplug before inspecting internal parts.

🛠️ 6. Check for Refrigerant Leaks
A refrigerant leak = no cooling.
- Look for oily residue or frost build-up
- Listen for hissing sounds
- If suspected, call a professional immediately
⚠️ Handling refrigerants is hazardous—never attempt repairs yourself.
🧼 7. Perform Regular Maintenance
Prevention is the best cure.
- Clean the interior and coils
- Inspect door seals
- Monitor temperature logs
- Schedule professional servicing at least once a year
📋 Keep a maintenance log to track inspections and tune-ups.
