Restaurant Equipment Repair

Restaurant equipment repair in Denver: reach-in refrigeration, prep tables, bar coolers, cooking lines and commercial dishwashers. The Appliance Team sends commercial technicians to restaurants, bars, cafes, school and church kitchens across the Denver metro and 30 surrounding cities. A commercial diagnostic is $129, and that fee is credited toward the repair if you go ahead. You get a written quote before any work starts, same-day or next-day commercial service, and a 90-day warranty on parts and labor. Our technicians are EPA 608 certified for refrigerant and sealed-system work.

Restaurant equipment we service

Restaurant equipment problems we fix

Dirty condensers are the first thing we check

Most warm reach-in calls start at the condenser. True’s control guide says a dirty condenser coil restricts airflow and keeps the system from running efficiently, and Traulsen calls coil cleaning the most important thing you can do for long equipment life. Kitchen grease and flour bind to the fins and act like a blanket. The compressor runs longer, runs hotter and eventually fails. Several manufacturers tie warranty coverage to regular coil cleaning: Beverage-Air states its warranty is void if coils are not cleaned at regular intervals, and True excludes coil cleaning from warranty coverage.

Prep tables: two temperatures in one box

A prep table has to hold both the cabinet and the pan rail at safe temperatures. When the rail is warm but the cabinet is cold, the cause is usually airflow: a failed rail fan, pans blocking the air path, or a lid left up between rushes. When both are warm, look at the condenser, evaporator and charge. We probe the pans themselves, because the display reads cabinet air.

Fryer lockouts and high limits

Commercial fryers have two layers of temperature protection: the controller probe and a separate high-limit thermostat. When a controller reports a high-limit or probe failure, stop using the fryer. Frymaster’s FQ4000 manual tells operators to shut down immediately on HOT-HI-1 and to disconnect power on HELP HI-2. Those are not reset-and-keep-cooking faults. We test the probe, the high limit, the ignition module and the gas valve and replace only what failed.

Commercial refrigeration and fryer error codes

Code meanings vary by brand, model and controller generation, and some cabinets in the same product line use different controllers. Use the tables below as a guide, write down the exact code and the model and serial number before you call, and take a photo of the display if you can. Many cabinets list the controller maker (Dixell, Danfoss, Carel) on the control itself.

True electronic controls (TRM merchandisers)

True controls without a display (Danfoss LED flash codes)

Some True cabinets have no temperature display. The control LED blinks once per second when power is on and no alarm is active. An alarm flashes in two blocks; count both.

Traulsen R, A, G, compact and TE/TU/TS series

Beverage-Air (Danfoss control)

Atosa and other Dixell XR06CX controls

Turbo Air reach-ins

On Turbo Air TSR/TSF reach-ins, the door alarm chirps three times after 30 seconds, five times after 60 seconds and continuously after 5 minutes. “Hi” and “Lo” show when cabinet temperature is outside the display range, and “dF” is a normal freezer defrost status. Recorded faults sit in a stored error mode that a technician opens from the keypad.

How a commercial repair visit works

Before you call: safe checks

• Write down the code on the display, plus the model and serial number. Traulsen puts them on the amp plate; Beverage-Air puts the dataplate inside the left wall.
• Check that doors and drawers close fully and nothing blocks them. A single sheet pan can hold a door open.
• Check the breaker. If it tripped, reset it once. If it trips again, leave it off and call.
• Vacuum or brush the condenser grille with the unit unplugged, and keep boxes away from the front and back vents.
• On a Pitco or Frymaster drain message, confirm the drain valve is fully closed before anything else.
• Move product to a working unit if a cooler reads above 41°F. Do not touch gas valves, wiring or refrigerant lines.

Denver notes: food code, altitude and water

Food code. Colorado adopted the FDA 2022 Food Code effective March 16, 2024. The Food Code requires cold holding of time/temperature control for safety (TCS) food at 41°F or below and hot holding at 135°F or above. A cooler that drifts to 44°F or a holding cabinet that sags below 135°F is an inspection problem as well as a food safety problem, so we treat those calls as urgent.

Dish machine temperatures. Food Code section 4-501.112 sets the hot-water sanitizing rinse at no more than 194°F at the manifold, and at least 180°F for most machines (165°F for a stationary rack, single-temperature machine). A booster heater that cannot keep up is a common call.

Gas cooking at altitude. Denver sits at about 5,280 ft. Gas appliances must be set up for elevation. For example, the Dean Triathlon gas fryer manual (a Frymaster product line) says that above 2,000 ft the rating should be reduced four percent for each additional 1,000 ft, and that the correct orifices are installed at the factory when the altitude is known at order. Used equipment brought in from a low-elevation city may have sea-level orifices. That can cause yellow flames, soot and slow recovery. We follow each manufacturer’s high-altitude instructions.

Steamers. Water boils at about 202°F at 5,000 ft (NMSU Extension), not 212°F. Steam equipment still works, but cook times and expectations differ from sea-level charts.

Water. Denver Water describes its water as soft to moderately hard, slightly harder in winter. Scale still builds in steamers, combi ovens and dish machine boosters over time, so descaling belongs on the maintenance list.

Repair or replace?

Most failures are parts: a fan motor, a probe, a gasket, a thermocouple, an ignition module. Those repairs almost always beat replacement. The harder calls are a failed compressor on an older reach-in, a cracked fryer pot or a failed combi steam generator. We weigh age, parts cost, parts support and what downtime costs you. Check your manufacturer’s warranty first: Turbo Air and Traulsen list 3 years parts and labor with 2 more years on the compressor, Atosa lists 2 years parts and labor plus 3 more on the compressor, and Beverage-Air lists 7 years on most units shipped after July 1, 2024. Terms vary by model. We repair in or out of the manufacturer’s warranty, and the choice of who does the work is yours. If a repair is not worth the money, we will tell you.

Businesses we work with

• School, corporate and hospital cafeterias: reach-ins, prep tables, walk-ins, ice machines and dish machines.
• Hospitals, senior living and clinics: kitchen refrigeration, ice machines and nourishment-room refrigerators.
• Hotels, bars, breweries and coffee shops: bar and back-bar coolers, keg coolers, undercounter units and ice machines.
• Offices, gyms and churches: breakroom and kitchen refrigerators, ice machines and commercial laundry.
• Warehouses, food production and commissaries: walk-in coolers and freezers and reach-ins.
