A GE refrigerator that freezes fresh food — turning lettuce to ice and cracking open containers — has a temperature regulation problem. Here's what's causing it.
Temperature Control Thermostat
The thermostat senses the refrigerator temperature and tells the compressor when to cycle off. When it fails, the compressor runs continuously, driving the temperature far below the 37°F target. Signs: everything in the fresh food section is frozen or partially frozen, freezer is extremely cold. Repair cost: $110–190.
Damper Control / Diffuser
The damper is a small door between the freezer and fresh food compartment that controls how much cold air enters. When it sticks open (often due to ice formation in humid Houston air), cold air flows constantly into the fresh food section. Signs: one side of the fridge is colder than the other, ice visible around the damper area. Repair cost: $120–200.
Temperature Sensor / Thermistor
The thermistor is a probe that reads the compartment temperature and relays it to the control board. A failed thermistor gives the board incorrect readings, causing it to keep the compressor running. Repair cost: $100–170.
Main Control Board
If thermostat and thermistor check out, the main board may be misinterpreting signals. Houston's summer power fluctuations can damage control boards. Repair cost: $200–380.
Quick Check
Set your fridge to 37°F and freezer to 0°F and wait 24 hours. If temperatures don't stabilize, it's time for a technician. ProFix GE-certified technicians serve all Houston zip codes with same-day availability.
GE Refrigerator Freezing Food in Houston: Causes and Fixes
A GE refrigerator that freezes food in the fresh food compartment — turning lettuce, fruit, and beverages into ice — is an extremely common service call in Houston homes. This problem is almost always caused by one of three components: the temperature sensor (thermistor), the temperature control damper, or the main control board. Here is how to diagnose which one failed.
Temperature Sensor (Thermistor) Failure
The temperature sensor monitors the temperature inside the fresh food compartment and signals the control board to open or close the damper that controls cold air flow. When the sensor fails and reads inaccurately cold, the control board thinks the refrigerator compartment needs more cooling — so it keeps the damper open continuously and cold air pours into the refrigerator section, freezing food. We test sensor resistance at room temperature (should be approximately 16,600 ohms at 50 degrees F on most GE models) before recommending replacement. Sensor replacement costs $25 to $45 for the part.
Temperature Control Damper Failure
The damper is a mechanical door between the freezer and refrigerator sections that controls how much cold air enters the fresh food compartment. If the damper is stuck in the open position — either from ice buildup or a failed actuator — cold air enters continuously and freezes food. This is particularly common in Houston after periods of high humidity. We inspect and test the damper on every food-freezing diagnosis. Houston's high humidity means ice bridging in the damper mechanism is more common here than in drier climates.
Control Board Repair
If both the sensor and damper test correctly, the control board has failed and is not regulating temperature properly. Control board replacement for GE refrigerators costs $80 to $250 depending on the model.
