Sub-Zero refrigerators are built to run 20 years or more, so when one warms up, leaks or throws an alarm, repair is almost always the right call. Our factory-trained technicians repair Sub-Zero fridges across Minneapolis, Saint Paul and the Twin Cities, including classic 500/600 built-ins, the BI and PRO series, integrated columns and undercounter drawers.

Root causes, ranked by what we find
What it is: Sub-Zero built-ins use two separate cooling systems. A failed evaporator fan, iced-over coil or bad thermistor on the fridge side warms only that section.
Fix: Test fan and sensor, clear the coil, replace the failed part with OEM.
Typical all-in: $385–$685 all-in
What it is: A seized condenser fan or a condenser packed with dust makes the compressor overheat and shut off. Very common on top-mount built-ins.
Fix: Clean the condenser, replace the fan motor, check compressor amp draw.
Typical all-in: $385–$585 all-in
What it is: High-temp, condenser and sensor alarms point to specific parts. We read the service-mode history before replacing anything.
Fix: Factory diagnostic mode, then the part the alarm actually points to.
Typical all-in: $385–$785 all-in
What it is: Inlet valve, frozen fill tube, clogged filter or failed ice maker module.
Fix: Replace valve, fill tube or module; clear the drain.
Typical all-in: $345–$625 all-in
What it is: Rare on Sub-Zero, but possible on older units. Confirmed with pressure testing before any quote.
Fix: Leak repair, compressor or drier replacement, evacuate and recharge.
Typical all-in: $1,200–$2,400, quoted in writing
Diagnostic order
Note any alarm code or flashing light and the set temperatures. Write them down for the technician.
On top-mount built-ins, lift the top grille and look for a dusty condenser. Light dust can be vacuumed with the unit turned off.
With the unit on, you should hear the condenser fan near the compressor. Silence plus a hot compressor points to a failed fan.
Make sure nothing blocks the doors and gaskets seal flat. A door left ajar triggers high-temperature alarms.
