Jenn-Air Refrigerator Error Code F3Eb

F3Eb indicates that the pantry compartment thermistor is not functioning correctly. The control board has detected that the sensor is either open-circuit or shorted, meaning it cannot accurately read the pantry temperature. This fault affects the refrigerator's ability to regulate the pantry zone's climate settings.

The refrigerator may continue to operate in other zones, but the pantry compartment temperature control will be unreliable while this fault is active. Food stored in the pantry area could be exposed to improper temperatures, which is a food safety concern. It is best to address the fault promptly or avoid storing perishables in the pantry zone until the repair is completed.

A power reset may temporarily clear the F3Eb code from the display, but the fault will return if the underlying problem with the pantry thermistor or its wiring has not been resolved. Running the manufacturer-specified Test 05 diagnostic is the correct way to confirm whether the fault is still present. A reset alone is not a substitute for proper diagnosis and repair.

A knowledgeable DIYer can attempt to resolve this fault by inspecting and reseating the thermistor wiring connector at the HV board pins P22-11 and P22-12. If the connector is secure and the wiring is undamaged, testing the thermistor with a multimeter and replacing it if it reads as open or shorted is a manageable repair. Work involving the high-voltage board should be approached with caution, and a qualified technician should handle that component if it is suspected to be faulty.

If the fix is simply reseating a loose connector, there may be no parts cost at all, with labor costs typically ranging from $75 to $150 for a service visit. If the pantry thermistor needs replacement, parts generally range from $20 to $60 depending on the specific model, plus labor. A high-voltage board replacement, if required, is a more significant expense, with parts alone often ranging from $150 to $350.
