Freezer never shuts off? We fix thermostats, clean coils, and replace gaskets. Same-day service, 90-day warranty. Average repair cost: $100–$350. Some causes are DIY-fixable — see below.
Freezer running constantly repair typically costs $100 to $350. Some causes are DIY-fixable, but professional diagnosis is recommended if the problem persists. Most repairs are completed in 1-2 hours with a free diagnostic visit.
A freezer running nonstop in Daly City's fog-saturated climate has a strong humidity explanation. This Peninsula fog-belt city of 105,000 residents maintains some of the Bay Area's highest year-round humidity, and summer highs of just 64°F mean the compressor has no thermal excuse for constant running. When it does, the primary cause is usually moisture — humid air pouring through a compromised gasket creates a load the defrost system can't clear and the compressor can't overcome. Dirty condenser coils, a stuck thermostat, and low refrigerant are secondary causes. Westlake tract homes from 1958 with compact kitchens provide the typical setting.
Daly City's persistent fog creates year-round peak humidity that makes gasket integrity the most critical factor for normal compressor cycling. The cool 64°F ambient eliminates heat as a factor entirely. Any constant running here is definitively a component issue — most commonly a gasket allowing the relentless humidity to overwhelm the system.
Dirty condenser coils
Damaged door gasket
Thermostat stuck
Low refrigerant
Hot ambient temperature
Dust, pet hair, and debris insulate the condenser coils, preventing heat dissipation. The compressor runs continuously trying to compensate. In Bay Area garages with limited ventilation and proximity to driveways, coils accumulate debris faster than in climate-controlled interiors.
Cost: $80–$150 | Time: 30-45 minutes
A compromised door seal allows warm air to enter continuously, raising the internal temperature. The thermostat never senses the target temperature is reached, so the compressor never cycles off. In humid Bay Area conditions, the constant warm moist air ingress amplifies the problem.
Cost: $80–$200 | Time: 30-60 minutes
A failed temperature control thermostat may remain in the closed (calling for cooling) position permanently, regardless of actual temperature. Power surges from PG&E grid fluctuations can damage electronic temperature controls in older Bay Area neighborhoods.
Cost: $100–$250 | Time: 45-75 minutes
A slow refrigerant leak reduces cooling capacity, causing the compressor to run endlessly without reaching set temperature. The freezer may be cool but not cold enough. Vibration from seismic activity unique to the Bay Area can stress brazed joints in evaporator tubing over years.
Cost: $200–$400 | Time: 2-3 hours

Constant-running repairs cost $100-$350 in Daly City. Gasket replacement at $80-$150 is the most common and most impactful fix. With 12 competitors serving 105,000 residents, the market is adequate. Bay Area service calls range $89-$150.
In Daly City, salt-laden marine air and persistent fog deposit corrosive moisture on metal surfaces and electronics. This can affect your appliance's evaporator coils: salt-laden moisture creates accelerated frost formation patterns that overwhelm defrost cycles Check defrost drain quarterly; ensure the garage or storage area is reasonably sealed from outside air
In Daly City, sustained relative humidity above 60% promotes mold growth, condensation on cold surfaces, and accelerated corrosion. This can affect your appliance's door gasket: warm humid air rushing in when the door opens creates rapid frost buildup on the evaporator, overwhelming the defrost system Minimize door opening time; check that the gasket seals fully by closing a dollar bill in the door — it should resist pulling
In Daly City, very low mineral content (<60 ppm tds) or sodium-softened water causes over-sudsing, rubber swelling, and reduced detergent rinsing. This can affect your appliance's ice formation quality: soft water produces clear but brittle ice that fractures into small shards, potentially jamming harvest mechanisms This is generally cosmetic; if ice jams occur, switch to a bypass filter that does not soften water for the freezer line
