A warm fridge is rarely the compressor. In most cases it's a frosted evaporator, a stuck damper, a failed evap fan, or a control-board defrost timer that never fires. We diagnose the exact failure before quoting — and we tell you honestly when a 12+ year unit isn't worth repairing.

Quick answer
If your refrigerator is not cooling, 5 causes cover ~95% of what we find: (1) frosted-over evaporator coil from a failed defrost system — $245–$385; (2) failed evaporator fan motor — $215–$335; (3) stuck or broken air damper between freezer and fridge — $185–$285; (4) bad start relay / overload on the compressor — $185–$265; (5) sealed-system leak (true compressor or refrigerant failure) — $0 (we recommend replacement). We diagnose first, then quote in writing. Flat $149 trip fee, waived on approval. 1-year written warranty.
Root causes, ranked by what we find
What it is: Freezer feels cold but the fridge is warm. The evaporator coil behind the freezer back-panel is encased in ice, blocking airflow into the fridge compartment. Caused by a failed defrost heater, defrost thermostat, or main control board defrost timer.
Fix: Diagnose the failed component (heater, thermostat, or board), thaw the coil, replace OEM part, verify defrost cycle.
Typical all-in: $245–$385 all-in
What it is: Freezer is cold, fridge is warm, and the freezer is quieter than usual. The fan that pulls cold air across the evaporator coil and into the fridge has stalled or seized — often after years of frost contact.
Fix: Replace OEM evaporator fan motor. Verify amp draw and airflow at the fridge vent.
Typical all-in: $215–$335 all-in
What it is: Freezer is correct, fridge is warm by 10–20°F. The motorized damper that meters cold air from freezer to fridge is stuck closed (or the damper motor has failed). Common on Whirlpool, KitchenAid, and Samsung side-by-sides.
Fix: Replace OEM damper assembly. Verify open/close cycle and fridge temperature recovery.
Typical all-in: $185–$285 all-in
What it is: Whole unit is warm — both freezer and fridge. You may hear the compressor click on and off every few minutes. The start relay (PTC) or overload protector has failed and the compressor never reaches running speed.
Fix: Replace OEM start relay/overload. Verify compressor amp draw and head pressure.
Typical all-in: $185–$265 all-in
What it is: Whole unit warm, compressor runs continuously, evaporator coil is partially frosted or completely frost-free. The sealed refrigerant loop has a leak or the compressor has internally failed.
Fix: On most residential units past 8 years, sealed-system repair runs $850–$1,400 and isn't worth it against replacement. We give you the honest math in writing — no upsell.
Typical all-in: $0 diag only (replacement recommended) or $850+
Diagnostic order
Place a thermometer in the freezer for 10 minutes. If freezer is above 10°F, you have a sealed-system or compressor issue (causes #4 or #5). If freezer is at 0°F and only the fridge is warm, you have an airflow problem (causes #1, #2, or #3).
Open the freezer with the door switch held. You should hear a soft fan running. Silence = stalled fan (cause #2). A loud whine or rattle = bearing failure, fan still pulling but degraded.
Unscrew the freezer back panel. If the evaporator coil is encased in ice rather than light frost, the defrost system has failed (cause #1). Thaw with a hair dryer to verify diagnosis.
On side-by-sides and French-doors, locate the air damper between the freezer and fridge compartments. Listen during a temp-recovery cycle — the damper should audibly cycle open/closed every 20–40 minutes.
If freezer is warm, clamp meter the compressor leads. No draw = open start relay or open compressor winding. Continuous high draw = restricted refrigerant flow (sealed-system).
FAQs
Repairs under $400 are almost always worth it on a unit under 12 years old. Sealed-system work over $800 on a 10+ year fridge usually isn't. We give you the honest math — diagnostic fee, repair quote, and a fair replacement comparison — in writing before any work begins.
Same-day across the Twin Cities (Minneapolis, Saint Paul, west metro) when you call before 2pm weekdays. Next-day for outer metro and Western Wisconsin. Refrigerator no-cool is our highest-priority dispatch tier.
No — keep it plugged in but turn the cold control to its warmest setting to reduce compressor cycling. Move perishables to a cooler. Unplugging won't speed up our arrival and can mask the failure pattern we need to see when we diagnose.
Most no-cool diagnostics resolve at $185–$385 all-in. Sealed-system or compressor work runs $850–$1,400 when it's worth doing. Flat $149 trip fee is credited to whatever repair you approve.
Yes — Sub-Zero, Thermador, Miele, Bosch, KitchenAid built-in, GE Monogram, and JennAir. Built-in repairs run higher (typically $385–$685) because access is more involved. Yes — that brand is part of our regular service mix. Diagnostic visit is the flat $149 trip fee, credited toward the repair if you approve the written quote.
Usually no. A fridge holds safe temps for 4–6 hours unopened. Move highly perishable items (raw meat, dairy) to a cooler with ice if we're more than 4 hours out. Most repairs are completed same-visit with truck stock.
