Fridge too cold and freezing food? We fix thermostat, sensor, and damper issues. Same-day repair with 90-day warranty. Average repair cost: $100–$250. Some causes are DIY-fixable — see below.
Refrigerator freezing food repair typically costs $100 to $250. Some causes are DIY-fixable, but professional diagnosis is recommended if the problem persists. Most repairs are completed in 1-1.5 hours with a free diagnostic visit.
Dublin's newer housing stock means food-freezing complaints often involve builder-grade appliances with electronic thermostats that may be improperly calibrated from the factory or have developed software glitches. Hot Tri-Valley summers of 91-95°F followed by winter lows of 39°F create seasonal transition food-freezing peaks. Dublin San Ramon Services District water at 260 ppm TDS can deposit scale on temperature sensors. Two-story homes with upstairs kitchens may experience different ambient temperatures than ground-floor kitchens. Built-in water softeners in newer developments protect sensors when maintained. About 7 providers serve Dublin.

Faulty thermostat
Defective temperature sensor
Damper control stuck open
Control board malfunction
Vent blockage
The mechanical or electronic thermostat fails in the "on" position, keeping the compressor running continuously. In Bay Area garages and unheated mudrooms where secondary fridges are common, cold ambient temperatures compound the over-cooling.
Cost: $120–$220 | Time: 45-75 minutes
The sensor sends incorrect readings to the control board, signaling the compartment is warmer than it actually is. The compressor over-runs to compensate. Moisture from Bay Area humidity can corrode sensor connections, causing resistance drift.
Cost: $100–$200 | Time: 30-60 minutes
The air damper between freezer and fresh food compartment regulates cold air flow. When stuck open, freezer-temperature air floods the refrigerator section. Frost from humidity cycles can jam the damper door in the open position.
Cost: $130–$250 | Time: 45-75 minutes
The main electronic control board misreads sensor inputs or fails to cycle the compressor off. Power fluctuations in older Bay Area homes with aging 60-amp panels can damage board circuits over time.
Cost: $180–$350 | Time: 60-90 minutes

In Dublin, wide day-night temperature swings (30f+ delta) stress thermal expansion joints, thermostat cycling, and sealed-system pressures. This can affect your appliance's sealed refrigerant system: rapid ambient temperature changes cause thermal shock to refrigerant lines, increasing the risk of micro-leaks at solder joints Keep the refrigerator away from exterior walls and windows with direct sun exposure; maintain consistent room temperature
