When it comes to compact refrigeration, under bench fridges are the unsung heroes of commercial kitchens. They offer convenience, conserve space, and support the pace of prep stations. But like any workhorse, they can run into trouble. Fortunately, you can fix most routine problems easily, with the correct know-how and a little elbow grease.

This guide explores frequent under bench fridge problems, how to identify them early, and what you can do to resolve them before they snowball into bigger issues.

1. The fridge is Not Cooling Properly

Symptoms:

Warm interior even when the compressor is running

Spoilage of temperature-sensitive ingredients

Fluctuating temperature readings

Quick Fixes:

Check the Thermostat Setting – Reset to the proper range (typically 0–4°C for food safety).

Clear Blocked Air Vents – Remove any pans or products obstructing airflow.

Clean Condenser Coils – Dusty coils reduce heat exchange; vacuum or brush off monthly.

Inspect Door Seals – Broken seals let warm air in; realign or replace if cracked.

Bonus ...
... Tip: Use a digital thermometer to verify the actual interior temperature rather than relying solely on the fridge’s display.

2. Strange Noises During Operation

Symptoms:

Humming, clicking, buzzing, or rattling sounds

Noise increases when the compressor activates

Quick Fixes:

Tighten Loose Panels or Feet – Vibrations often come from unsecured external parts.

Check Fan Blades – Something may be obstructing them (e.g., bits of packaging).

Inspect Compressor Mounts – Rubber grommets may have worn out, causing metal-on-metal noise.

Move the Unit Slightly – Sometimes, uneven flooring creates vibration loops.

Pro Tip: A louder-than-usual buzzing sound might indicate a failing compressor—monitor it closely.

3. The Interior Light is Not Working

Symptoms:

No light when the door opens

Flickering or dim illumination

`Quick Fixes:

Replace the Bulb – Use manufacturer-approved LED or incandescent units.

Check the Door Switch – Often a spring-loaded component; clean or replace if jammed.

Inspect Electrical Connections – Loose wires near the light casing can interrupt the flow.

Safety Note: Always unplug the fridge before touching any electrical components.

4. Door Not Closing Properly

Symptoms:

The door feels loose or sits unevenly

Condensation around the seal

Temperature drop near the hinge

Quick Fixes:

Clean and Lubricate Hinges – Built-up grime or corrosion can cause resistance.

Replace Gaskets – Cracked or flattened rubber prevents airtight sealing.

Manage Door Alignment – Tighten hinge screws or softly reposition the gate using a screwdriver.

Check for Obstructions – Product overload or trays sticking out may stop the door from entirely shutting.

Efficiency Boost: A properly closed door maintains temperature and reduces energy waste.

5. Excessive Ice Build-Up

Symptoms:

Frost on the interior walls or fan vents

Icy shelves or product packaging

Slower cooling performance

Quick Fixes:

Manual Defrost – Unplug the unit, leave doors open for several hours, and dry thoroughly.

Reduce Door Openings – Frequent access lets in moist air that turns to frost.

Check for Seal Gaps – Recalibrate or replace door seals that allow warm, moist air inside.

Inspect Defrost Cycle Settings – Some advanced fridges allow manual defrost cycle adjustment.

Pro Insight: Ice build-up is a signal that your fridge is overworking. Tackling it early saves long-term damage.

6. Temperature Display Is Inaccurate

Symptoms:

The digital display doesn't match the actual fridge temperature

Temperature "drift" throughout the day

Quick Fixes:

Use an Independent Thermometer – Compare with internal digital display for verification.

Calibrate the Thermostat – Refer to the user manual for reset or adjustment instructions.

Replace Faulty Sensors – Thermistors can degrade over time; swap them out if needed.

Update Firmware (if applicable) – Smart fridges may require software updates to fix display errors.

Bonus Tip: Log temperature readings at different times to spot patterns or display lags.

7. Fridge Won’t Turn On

Symptoms:

No sound or light from the unit

Non-responsive control panel

Quick Fixes:

Check Power Source – Confirm plug is secure; test with another appliance.

Inspect Circuit Breaker – Reset the breaker if tripped.

Examine Power Cord – Frayed or damaged cords need replacement immediately.

Press Reset Button – Some fridges include internal or rear panel resets.

Important: If all else fails, a faulty control board or compressor may need professional service.

8. Unusual Smells Inside the Fridge

Symptoms:

Stale, sour, or chemical odours upon opening

Smell clings to product packaging

Quick Fixes:

Clean the Interior Thoroughly – Use mild bleach solution or food-safe cleaners.

Check for Spoiled Items – Remove anything leaking or expired.

Replace Air Filters (if present) – Some premium models include odour filtration.

Place Baking Soda or Activated Charcoal Packs – These absorb residual smells naturally.

Chef Tip: Regular cleaning and rotation of products eliminate long-term odour issues.

9. Fan Not Working Properly

Symptoms:

Warm patches inside despite the compressor running

No audible fan operation when the door is open

Quick Fixes:

Clear Blocked Vents – Ingredients or packaging may be obstructing the fan area.

Reset the Fridge – Unplug, wait five minutes, then power on to reset fan control.

Inspect Fan Blades & Motor – Dirt, ice, or damage can stop movement.

Replace Fan Assembly – If the motor has burned out, a replacement is needed.

Pro Insight: A working fan ensures uniform chill. Without it, your fridge becomes uneven and unpredictable.

10. Fridge Cycling Too Frequently

Symptoms:

The compressor turns on and off rapidly

Constant humming throughout service hours

Temperature never fully stabilises

Quick Fixes:

Inspect Thermostat Sensor Placement – Sensors too close to cold air outlets can misread the temperature.

Check Door Seals – Air leakage forces the compressor into overdrive.

Clear Condenser Coils – Poor heat dissipation triggers premature cycling.

Don’t Block Airflow – Allow 5 cm clearance behind and to the sides for ventilation.

Long-Term Solution: Continuous cycling results in added wear—determine causes early to reduce burnout.

Preventive Maintenance for Long-Term Performance

Keeping your under bench fridge in tip-top shape isn’t about reacting—it’s about preventing problems before they arise. Add these to your kitchen’s routine checklist:

Weekly:

Wipe down interior and gasket seals

Confirm thermostat readings

Inspect for frost or drainage issues

Monthly:

Clean condenser coils and exterior surfaces

Check fan operation and clear vents

Look for unusual smells or condensation

Quarterly:

Test door alignment and seal integrity

Verify calibration of temperature sensors

Review electrical and plug connections

Smart Tip: Keep a maintenance log that includes service dates, issues identified, and fixes applied.

When to Call in the Pros?

If your fridge is exhibiting signs of more serious issues—such as complete cooling failure, recurring electrical problems, or persistent compressor trouble—it’s time to call a certified technician. While many quick fixes are DIY-friendly, professional services:

Ensures electrical safety

Preserves warranty validity

Prevents long-term equipment damage

Diagnoses complex mechanical issues

Conclusion

Under bench fridges are crucial performers in commercial hospitality establishments. But they’re also prone to wear from constant access, tight spaces, and demanding service hours.
