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.
Redwood City's warmer Peninsula microclimate with summer highs of 80-85°F means food-freezing complaints are relatively uncommon during warm months — the compressor works hard enough to maintain temperature without over-cooling. Winter and transition seasons produce the bulk of complaints as ambient temperatures drop and thermostats struggle to adjust. Diverse housing from early 1900s cottages to modern townhomes means varied appliance ages and thermostat types. Water at 200 ppm TDS can deposit moderate sensor scale. About 10 providers serve the area.

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
