What F5 means on a GE refrigerator
The F5 error code on a GE refrigerator indicates a fault with the deli pan thermistor. This thermistor is a temperature-sensing resistor located in or near the deli pan compartment, and it continuously reports temperature data to the main control board. When the control board detects that the thermistor signal is outside the expected range, either because the thermistor circuit is shorted, open, or reading a temperature value that falls outside normal operating parameters, it triggers the F5 code. The deli pan compartment is designed to maintain specific temperature conditions for storing meats and cheeses, so accurate thermistor readings are critical to proper zone temperature management.
A shorted thermistor means the resistance has dropped too low, causing the control board to read an erroneously high temperature or an invalid signal. An open thermistor means the circuit has broken entirely, sending no signal or an out-of-range voltage to the board. Either condition prevents the control system from regulating the deli pan temperature correctly. Physical damage to the thermistor, wiring harness failures, or connector corrosion are the most common underlying causes.
Diagnosis begins with measuring the thermistor resistance using a multimeter and comparing the reading to the expected resistance range for the operating temperature. A thermistor that reads infinite resistance is open, and one that reads near zero ohms is shorted. Both conditions require thermistor replacement. If the thermistor resistance reads within a normal range, the wiring harness and connector between the thermistor and control board should be inspected for damage, corrosion, or loose connections before concluding the control board itself is at fault.

Common causes of F5
- 01
Failed Deli Pan Thermistor
Part replacementThe thermistor itself has failed internally, either going open circuit or shorted. A multimeter reading of infinite resistance or near zero ohms on the thermistor confirms this condition.
- 02
Damaged Wiring Harness
Part replacementThe wiring between the deli pan thermistor and the control board may be pinched, cut, or broken, interrupting the signal. Visually inspect the wire routing and check for continuity along the full length of the harness.
- 03
Corroded or Loose Connector
Wiring / connectionThe thermistor connector at either end can develop corrosion or work loose over time, causing an intermittent or completely invalid signal. Inspect the connector pins for green or white oxidation and ensure the connector is fully seated.
- 04
Moisture Intrusion at Thermistor
Part replacementCondensation or water from food spills can reach the thermistor or its connector, causing shorts or accelerated corrosion. Look for signs of water damage or residue near the sensor and harness connection points.
- 05
Faulty Main Control Board
Part replacementIf the thermistor and all wiring test within normal parameters, the control board may be misreading or failing to process the thermistor signal correctly. This is the least likely cause and should only be considered after all other components have been ruled out.
