Jenn-Air Range Error Code F5

F5 on a Jenn-Air range indicates a shorted temperature probe, probe jack, or wiring harness in the oven temperature sensing circuit. The control board has detected an abnormally low resistance signal, which it interprets as a short circuit. The oven will not operate normally until the fault is diagnosed and corrected.

You should not attempt to use the oven while F5 is active. The error indicates the temperature sensing circuit is not functioning correctly, meaning the oven cannot accurately monitor or regulate its internal temperature. Continuing to operate the oven under these conditions could result in overheating or inconsistent cooking results.

Repair costs depend on which component is at fault. A replacement temperature probe typically costs between $20 and $60 for the part alone. If professional labor is needed, total repair costs including diagnosis and installation commonly range from $100 to $250. Harness or jack repairs may fall in a similar range depending on the extent of the damage.

Some causes of F5 are DIY-friendly. Start by inspecting the probe jack and harness for obvious damage or a loose connection, and reseat the probe firmly. If the connection looks good, use a multimeter to test the probe resistance. A probe reading near zero ohms needs replacement, which is a straightforward part swap for most technicians and skilled DIYers.

Resetting the range by cutting power at the breaker for a few minutes may temporarily clear F5, but the code will return if the underlying short is still present. A reset is useful for confirming whether the fault is intermittent or persistent, but it does not repair the shorted probe, jack, or harness causing the code.
