GE Refrigerator Error Code FP: Freezer Probe Error
Complete troubleshooting guide for GE refrigerator FP error code - freezer temperature sensor malfunction
Technical Diagram

Expert Diagnosis
The FP error indicates the freezer temperature probe (thermistor) is providing incorrect readings or has failed. This sensor monitors freezer temperature to control cooling cycles. A faulty probe can cause temperature fluctuations, excessive cooling, or inadequate freezing.
What This Error Means
The FP error code on your GE refrigerator indicates a Freezer Probe Error. This means the temperature sensor that monitors the freezer compartment is malfunctioning. The refrigerator may not maintain proper freezer temperature, leading to food safety concerns.
Common Causes
Faulty Temperature Sensor
The freezer thermistor probe has failed and is sending incorrect temperature readings
Damaged Sensor Wiring
Wires connecting the sensor to the control board are broken, pinched, or corroded
Loose Connections
Sensor connector is not properly seated or has poor electrical contact
Sensor Displacement
The probe has moved from its proper position and is not reading accurate temperature
Control Board Malfunction
The main control board is not processing the sensor signal correctly
Step-by-Step Solutions
Step 1: Power Reset
- Unplug the refrigerator from the outlet
- Wait 5 minutes to reset the control board
- Plug back in and check if error clears
- Monitor freezer temperature for 24 hours
Step 2: Inspect Sensor Connections
- Unplug refrigerator for safety
- Locate the freezer temperature sensor (usually near evaporator)
- Check that connector is firmly attached
- Look for any visible damage to wires or connector
- Reconnect if loose
Step 3: Test Freezer Sensor
- Disconnect the sensor from the wiring harness
- Use a multimeter set to resistance (ohms)
- Test sensor resistance at freezer temperature
- Compare reading to specifications (typically 10-50k ohms at 0°F)
- Replace sensor if reading is infinite, zero, or out of range
Step 4: Check Sensor Position
- Verify sensor is properly positioned in freezer compartment
- Ensure sensor tip is making good contact with mounting surface
- Check that sensor is not frozen in ice or frost
- Reposition if necessary and secure properly
Step 5: Professional Service Required
- If sensor tests good but error persists, control board may be faulty
- Sensor replacement requires accessing internal components
- Contact GE authorized service: 1-800-432-2737
- Technician has proper diagnostic tools and replacement parts
Safety Warning
Always unplug the refrigerator before accessing internal components. The freezer compartment may contain extremely cold surfaces and sharp edges. If you're not comfortable with electrical testing, contact a professional technician.
