Refrigerator Not Cooling

When the fridge runs but food stays warm

A fridge that runs but doesn’t cool is one of our most common calls in San Francisco and around the Bay Area. Milk goes off, leftovers turn, and the freezer may still feel cold, or both sides warm up together. Before you empty it or shop for a new one, it helps to rule out the simple airflow and settings problems. The rest needs a licensed technician.

Bay Appliance Repair diagnoses refrigerator not-cooling symptoms Monday to Friday, 8:00 AM to 5:00 PM. We are based at 140 San Pedro Rd, Daly City, CA 94014 (Bay Appliance Repair). Service calls only, no walk-in counter. Call 415-585-5900 or email service@bayappliancerepair.com. California BEAR #46247.

Common causes (high level)

A warm fridge rarely means a dead compressor. Often the coils are packed with dust, a full shelf is blocking the vents, the door gasket is leaking cold air, or the defrost system has iced over the evaporator. Controls and temperature sensors can also act up after a power blip. Sealed-system leaks and compressor failures do happen, but they take gauges and recovery equipment, so they’re not a weekend project.

• Dirty condenser coils or blocked rear/side airflow
• Overloaded shelves blocking cold-air vents between fridge and freezer
• Door ajar, warped gasket, or frequent long door openings
• Defrost heater, sensor, or control board faults causing ice on the evaporator
• Failed evaporator fan, condenser fan, start relay, or temperature control
• Low refrigerant or sealed-system issues (pro diagnosis only)

Safe checks you can do before calling

These are look-and-check steps only. Don’t open live electrical panels or sealed refrigerant lines:

• Confirm the unit is plugged in and the wall outlet has power; check the breaker if the interior light is also out.
• Verify temperature controls are not set to Off or an unusually warm setting.
• Clear the vents between the freezer and fridge sections, and pull the fridge a few inches from the wall so air can reach the coils.
• Feel the door gasket for obvious gaps; wipe crumbs that keep the door from sealing.
• Listen for the evaporator fan (inside freezer) and condenser fan (near coils) when the compressor is running.

Do not puncture lines, add refrigerant, bypass safety switches, or open sealed electrical compartments. If you smell burning insulation, see scorched wiring, or hear hard clicking from the compressor area, unplug if safe and call a pro.

When to call for refrigerator repair

Call when food is warming despite normal settings, frost builds heavily on the evaporator cover, the compressor never starts or short-cycles, water pools under the unit from a blocked drain, or the fridge warms again within hours of a temporary “recovery.” Same-day service available. Hours are Monday-Friday, 8am-5pm. If it’s loud as well as warm, see refrigerator making noise.

In San Francisco, book through San Francisco refrigerator repair. If it’s a standalone freezer, see San Francisco freezer repair.

What to expect on a visit

We check the symptoms, airflow and fans, test the controls and defrost, and go over the options before ordering parts. Many fridges that stop cooling can be fixed without replacing them when the liner and sealed system are sound. Our technicians are EPA 608 certified (Type I and II), and you get the exact price before any work starts, with no hidden fees.

Common questions

What is the most common fridge failure?

There isn't one single failure, but the most common cooling problems we see are dirty condenser coils, failed evaporator or condenser fans, defrost faults that ice over the evaporator, and worn door gaskets. Many are repairable without touching the compressor. Clear the vents and check that the door seals; if it's still warm, schedule a diagnosis.

How do I reset a refrigerator compressor?

Most home refrigerators have no compressor reset button. A start relay and overload protector restart the compressor automatically. Unplugging the fridge briefly and checking the temperature setting is the only safe reset. If the compressor clicks on and off without running, or never starts, the relay, overload or compressor needs a technician's diagnosis.

Does unplugging a fridge reset it?

Unplugging it briefly can reset the electronic control on many refrigerators and clear a glitch, for example after a power outage. A longer unplug with the doors open (a manual defrost) can help for a while if ice is blocking airflow. It won't fix a failed fan, sensor or compressor. If it warms up again, schedule a diagnosis.

How to tell if a fridge compressor is faulty?

Warning signs include a compressor that clicks on and off without running, hums but won't start, or runs constantly while both sections stay warm. Unusual heat or loud noise is another sign. Many of these symptoms actually come from a bad start relay, a stopped condenser fan or dirty coils, so have it tested before assuming the compressor is dead.
