Temperature Control Error
Quick Answer
Error code tC on your GE Refrigerators means: Temperature Control Error. This is usually fixable — see the step-by-step guide below.
Affected Models
Likely Causes
  1. Temperature sensor (thermistor) in the fridge or freezer has failed
  2. Wiring to the temperature sensor is damaged or disconnected
  3. Control board is not reading the sensor value correctly
  4. Sensor connector has corroded pins
How to Fix It
1
Identify which compartment (fridge or freezer) has the incorrect temperature to narrow down the faulty sensor
2
Unplug the refrigerator and locate the thermistor for the affected compartment (usually clipped to the evaporator or mounted on the compartment wall)
3
Disconnect the thermistor and measure its resistance with a multimeter (approximately 16k ohms at 32 degrees F, 5k ohms at 77 degrees F)
4
If the reading is far outside the expected range, replace the thermistor
5
Check wiring connections from the sensor back to the main control board
Pro Tip
This fix requires some technical knowledge. If you're unsure about any step, consider contacting support or a qualified technician.
