Commercial Reach-In Refrigerator and Freezer Repair

Home › Refrigeration by industry › Reach-in cooler and freezer repair

Reach-in refrigerators and freezers do the hardest work in a kitchen: doors open hundreds of times a shift, often next to a fryer line. Cool Aid repairs commercial reach-ins, undercounters and upright freezers for restaurants, hotels, cafes and stores across the Bay Area, and we are factory-authorized service for True Manufacturing, Traulsen and Turbo Air.

Common reach-in problems

Cabinet running warm

The first suspect is the condenser. A reach-in that cannot shed heat cannot hold temperature. Turbo Air tells owners to clean the condenser coil at least every three months, and True's maintenance table has condenser checks monthly, quarterly and annually (Turbo Air) (True). After that we check the evaporator fan, the evaporator for ice, door gaskets and the controller.

Ice on the evaporator or frost inside

Torn gaskets, doors that do not close and a failed defrost cycle let moisture freeze on the coil. The cabinet warms up even though the unit runs constantly.

Water on the floor or in the cabinet

Blocked drain tubes, a cracked drain pan or an evaporator pan that is not evaporating. See refrigeration water leaks for what to check first.

Loud, clicking or not starting

Condenser fan motors, start components, relays and compressors. Our compressor problems guide covers the signs.

R-290 (propane) reach-ins

Many newer reach-ins, including True units, use hydrocarbon refrigerant such as R-290. True's manual says only qualified technicians should install and service these units and that components should be replaced with original equipment manufacturer parts (True). EPA requires flammable-refrigerant equipment to be marked, including red hoses or piping and marked service ports (EPA). Our technicians are trained on R-290 and the other low-GWP refrigerants now going into commercial equipment.

Repair or replace a reach-in?

Consider age, repair history, refrigerant and energy use. If you replace:

• New self-contained commercial refrigeration units have been limited to refrigerants with a GWP under 150 since January 1, 2025 (40 CFR 84.54).
• DOE efficiency standards for commercial refrigerators and freezers are the ones in effect since 2017 (10 CFR 431.66). A stricter rule finalized in January 2025 was withdrawn in May 2025 (Federal Register).
• ENERGY STAR certified commercial refrigerators and freezers are on average about 20 percent more efficient than standard models (ENERGY STAR).
• The California Foodservice Instant Rebates program lists glass or solid door refrigerators and freezers at $50 to $100 per unit, taken off the invoice at participating dealers, while funds last (program flyer).

Our repair or replace guide walks through the decision.
