This guide answers the most common questions about true commercial refrigerator not cooling with 2026 Twin Cities pricing, brand-specific fixes, and when to call a factory-trained tech.
Quick answer: About 9 out of 10 True commercial refrigerator "not cooling" calls trace to a clogged condenser coil, a failed evaporator fan motor, or a worn start relay/capacitor on the compressor — not the sealed system. Vacuum the condenser, confirm the evap fan spins when the door is closed, and feel the compressor for vibration. If the compressor is hot and silent, replace the start relay ($45 part, $245–$345 installed) before condemning the unit. Sealed-system work runs $695–$895.

What's actually wrong when a True refrigerator stops cooling
True Manufacturing builds three commercial workhorses you'll find in every Twin Cities back-of-house: the T-23 (single-door reach-in, ~23 cu ft), the T-49 (two-door reach-in, ~49 cu ft), and the GDM glass-door merchandiser line for c-stores and bars. All three share the same R-290 hydrocarbon refrigeration platform on post-2019 builds and the same wiring archetype: a single PSC compressor, an evaporator fan (often two on T-49s), a condenser fan, and a defrost timer driving everything off a mechanical or digital thermostat. When the box runs warm, the failure is almost always upstream of the sealed system.

This is the single highest-value 15 minutes you can spend on a True. Unplug the unit. Remove the louvered front grille (two Phillips screws on T-23/T-49). Vacuum the coil from the front with a soft brush attachment, then spray a non-acid foaming coil cleaner (Nu-Calgon Evap Pow'r or equivalent), wait 5 minutes, and rinse with a pump sprayer. Restaurants on a fryer line should clean condensers monthly; bar-only locations every 90 days. A coil packed with cottonwood seed and fryer grease can cut cooling capacity in half — we measure it every week in the Twin Cities during June.
What does a True T-49 evaporator fan replacement cost?
On a True T-49 with the dual-evap-fan platform, a single motor failure (Fasco K167 or equivalent) shows up as warm product on one half of the cabinet. OEM motor and blade together run $95–$140; installed on-site with a 1-year parts and labor warranty, expect $285–$385 — including the $149 trip fee which is credited to the repair. We stock the K167 and the Mars 10464 universal on every truck.
True compressor won't start — relay or compressor?
If the compressor is hot to the touch and you hear a click every 2–3 minutes from the overload, that's almost always the start relay/capacitor, not the compressor itself. A Supco 3-in-1 hard-start kit ($35 part) will tell you in 60 seconds: install it, and if the compressor spins up, the relay was the failure. If it still won't start, the compressor windings are open and you're looking at $695–$895 for a sealed-system swap (or a replacement unit decision — see below).
True refrigerator repair vs replace: when does it stop making sense?
A True T-49 in a healthy kitchen lasts 12–15 years. If the cabinet is past 10 years AND you're facing a compressor or evaporator coil leak, we walk owners through the math: a sealed-system rebuild is $895–$1,295, a comparable new T-49 is $4,200–$4,800. Below the 8-year mark, repair almost always wins. Past 12, replace — energy savings on the new ENERGY STAR R-290 platform pays back the difference in 18 months for a 24/7 reach-in.
How fast can you get to a down True cooler in the Twin Cities?
Commercial dispatch is same-day for calls received before 11 a.m. Mon–Sat across Minneapolis, St. Paul, Edina, Bloomington, Eden Prairie, Maple Grove, Woodbury, Eagan, Hudson WI, and River Falls WI. After-hours emergency rate applies nights and Sundays. We carry the high-failure True parts (K167 evap motor, 3-in-1 hard start, GDM door gaskets, Digi-Stat thermistors) on every commercial truck, so most calls are one-trip fixes.
What about Traulsen and Beverage-Air — are the failures the same?
Mostly yes. Traulsen reach-ins (G-series, RHT) fail at the evaporator fan and the Klixon defrost terminator at almost identical rates. Beverage-Air (KR/HR series) tends to fail at the start components first because of the smaller compressors used. The diagnostic order — condenser, evap fan, start relay, sealed system — is universal across all three. See our brand-specific pages for True repair, Traulsen repair, and Beverage-Air repair.
