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 that won't stop running in your Novato home reflects the heat stress of northern Marin's 86°F summers on an efficiency-compromised system. Novato's 55,000 residents live in suburban tract homes from 1978, where garage placement puts freezers in the warmest local environment. Dirty coils, heat-degraded gaskets, and thermostat malfunction are the standard causes, with the warm climate providing less margin for these efficiency losses than cooler coastal Marin cities.
Novato's 86°F heat is the warmest in Marin, creating less margin for efficiency losses than coastal communities. Suburban tract garages from 1978 provide standard environments.
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 Novato. With 5 competitors, San Rafael providers supplement availability. Bay Area service calls range $89-$150.
In Novato, wide day-night temperature swings (30f+ delta) stress thermal expansion joints, thermostat cycling, and sealed-system pressures. This can affect your appliance's compressor: cold overnight temperatures reduce compressor load, then daytime heat spikes force maximum output — this cycling is harder on the motor than steady operation Place standalone freezers in climate-controlled spaces; garage freezers in extreme climates fail 2-3 years earlier
In Novato, 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
