If your walk-in cooler suddenly stops cooling, your inventory and your revenue can start melting away fast. Whether you run a convenience store, restaurant, grocery store, or food prep facility, an unexpected refrigeration failure can disrupt your entire operation.

At TrueServ Mechanical, we specialize in commercial walk-in cooler repair and emergency response services. From system diagnostics to part replacements, our commercial refrigeration technicians know how to get your walk-in unit back online fast.

In this blog, we’ll walk you through what causes walk-in coolers to fail, what you can do first, and when to call in a professional.

A walk-in cooler is a complex machine. Even a small malfunction can throw off the entire system’s ability to maintain proper temperature. Some of the most common causes of failure include:

Thermostat or Control Failure: When the temperature sensor isn’t calibrated or fails, your system may think it’s at the right temp when it’s not or fail to cycle on at all.

Dirty or Blocked Condenser Coils: Dust, grease, or debris on condenser coils prevent the system from releasing heat effectively. This forces it to work harder and fail faster.

Refrigerant Leaks: Low refrigerant levels reduce cooling capacity and may lead to compressor failure if left untreated. This is a common culprit behind underperformance.

Electrical Issues: Faulty wiring, tripped breakers, or control board problems can shut your unit down entirely or prevent it from cycling correctly.

Ice Buildup or Drainage Problems: Water condensation that doesn’t drain properly can freeze on evaporator coils, blocking airflow and leading to temperature drops—or rises.

 

First Steps: What to Check Before You Call

If your cooler suddenly stops working or isn’t holding temperature, here are a few steps to check before calling for service:

• Check the power supply – Make sure the unit hasn’t lost power due to a tripped breaker or outlet issue.

• Inspect the thermostat – Ensure it’s set correctly and hasn’t been accidentally adjusted.

• Listen for fan and compressor sounds – If you hear silence, that’s a sign of an electrical or control failure.

• Look for frost or ice buildup – That could indicate an airflow or defrost cycle issue.

• Check the door gasket – A broken seal can allow warm air to leak in, causing the unit to overwork.

Still not cooling? It’s time to call for commercial walk-in refrigerator repair.

Should You Repair or Replace Your Walk-In Cooler?

Not sure whether to repair or replace? Consider these factors:
