Walk In Cooler Repair: What to Do When Your System Stops Cooling
In this guide, you’ll learn why walk in coolers fail, the first steps to take, and when to call for commercial walk in cooler repair.

Why Cooling Systems Fail
A walk in cooler is a complex system with multiple components that must work together. Even a small failure can throw off temperature control. Common causes 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. As a result, it is forced to work harder and can fail faster.
Refrigerant Leaks: Low refrigerant levels reduce cooling capacity and may lead to compressor failure if left untreated. This issue is a frequent culprit behind underperformance.
Electrical Problems: 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.
Quick Troubleshooting Before You Call for Service
If your cooler suddenly stops working or isn’t holding temperature, here are a few steps to check before calling for service:
First, check the power supply – Make sure the unit hasn’t lost power due to a tripped breaker or outlet issue.
Next, inspect the thermostat – Ensure it’s set correctly and hasn’t been accidentally adjusted.
Then, listen for fan and compressor sounds – If you hear silence, that’s a sign of an electrical or control failure.
After that, look for frost or ice buildup – That could indicate an airflow or defrost cycle issue.
Finally, check the door gasket – A broken seal can allow warm air to leak in, causing the unit to overwork.
If none of these solve the problem, it’s time to call for walk in cooler repair near me. For service in the DFW Mid Cities and beyond for multi-location businesses, call TrueServ Mechanical at 972-693-2604.

Should You Repair or Replace Your Walk-In Cooler?
If you’re unsure whether repair or replacement is the best option, consider the following:
● Age of the unit – Systems over 12–15 years old may not be worth extensive repairs.
● Frequency of breakdowns – If you’re calling us every month, it’s time to upgrade.
● Energy efficiency – New systems can reduce energy costs by 20–40% over older models.
● Refrigerant phase-out – If your system uses R-22, repairs may no longer be cost-effective due to phased-out refrigerant availability.
We’re happy to help you evaluate your options, including providing quotes and commercial refrigeration equipment financing to make upgrades easier.
For efficiency standards and best practices, review the commercial refrigeration efficiency guidelines from the U.S. Department of Energy.
