GE Wine Cooler TEMP-ERR Error: Temperature sensor circuit fault
This guide covers GE wine cooler TEMP-ERR error in detail to help you diagnose and resolve the issue. What Does GE Wine Cooler TEMP-ERR Mean? TEMP-ERR means the control board detected a fault in the interior temperature sensor circuit — either an open or shorted thermistor, or a broken wiring connection between the sensor and […]
Quick Assessment
Answer to continue safely
Is it safe to keep using?
No. Without a functional temperature sensor the control board cannot maintain a stable cabinet temperature. The compressor may over-cool or fail to cool at all. Do not rely on the wine cooler for temperature-sensitive storage until the sensor is repaired.
Can I reset the code?
Yes. A 5-minute hard reset clears the TEMP-ERR display. If the sensor is physically failed, TEMP-ERR returns within one compressor cycle. A reset that holds for 24 hours without recurrence indicates a transient fault.
When to stop immediately?
Stop if you notice: TEMP-ERR returns within 30 minutes of every reset — sensor replacement required, Cabinet temperature is swinging more than 10 degrees — compressor damage risk.
Symptoms You May Notice
Temperature display shows dashes or an implausible reading
Instead of a stable temperature, the display shows "---", "EE", or a wildly inaccurate reading (e.g., 0°F or 99°F) — indicating the sensor is not transmitting a valid signal to the control board.
TEMP-ERR displayed and compressor cycles erratically
Without a valid temperature reading, the control board cannot regulate the compressor properly — it may run continuously, not run at all, or cycle on and off far more frequently than normal.
HI and LO alarms trigger at random intervals
A sensor sending intermittent false readings causes both HI and LO alarms to fire without any corresponding actual temperature change in the cabinet.
Cabinet temperature unstable — alternately too warm and too cold
Wine bottles fluctuate between being too warm and too cold as the erratic compressor cycling caused by the faulty sensor creates temperature swings rather than maintaining a stable set point.
Possible Causes
Failed internal temperature sensor (thermistor)
The NTC thermistor mounted inside the cabinet has failed open or short, sending an out-of-range signal to the control board that cannot be interpreted as a valid temperature.
Requires ProfessionalLoose or corroded thermistor wiring connector
The connector linking the temperature sensor to the control board has developed a loose pin or corroded terminal, causing intermittent loss of the sensor signal.
DIY PossibleControl board temperature sensor input circuit failure
The sensor input circuit on the main control board has failed, causing it to report a fault even when the thermistor and wiring are intact.
Requires ProfessionalSafe Checks You Can Do
-
1
Hard-reset the control board
Unplug the wine cooler for 5 full minutes, then restore power. A 5-minute reset allows all board capacitors to fully discharge and can clear a transient sensor fault caused by a voltage spike or momentary connector interruption.
If TEMP-ERR clears after the reset and the temperature display reads stably for 24 hours, the fault was transient. Monitor over the next week — intermittent connector faults often return.

2
Check the temperature against an independent thermometer
Place an independent kitchen thermometer inside the cabinet on the middle shelf. If the independent thermometer reads a reasonable temperature (45°F–65°F) while the panel displays TEMP-ERR or an implausible value, the wine cooler sensor is faulty rather than the cabinet being at a dangerous temperature.
Knowing the actual cabinet temperature helps you decide whether to leave wines in place or move them during a service wait.

Move temperature-sensitive wines if cabinet control is lost
If TEMP-ERR causes erratic compressor cycling and the cabinet temperature is unstable, move valuable or sensitive bottles to your household refrigerator (set to its warmest setting, around 40°F) until the sensor is repaired.
Most household refrigerators are too cold for long-term wine storage, but they protect wine from heat damage during short service waits of a few days.
When to Call a Professional
Contact a qualified technician if:
- TEMP-ERR persists after a 5-minute reset on two consecutive days — hardware sensor fault confirmed
- Display shows fixed implausible value (0°F or 99°F) on every startup — control board input fault
