Error codeF1-5 / F1-8
ApplianceWall Oven
Quick answer
One JennAir range entry covers both F1-5 and F1-8: oven control, keypad or interface, and wiring.
Model compatibility: JennAir reuses codes across series and model years, so F1-5 / F1-8 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
F1-5 and F1-8 are a possible problem with the Oven Control, the User Interface or Keypad, or the wiring.
The range page from JennAir gives F1-5 and F1-8 the same text. Neither appears on the wall oven pages.
Where JennAir says to look
The oven control
The user interface or keypad, meaning the part you press
The wiring tied to them
The entry combines two sets that JennAir otherwise splits: keypad-only codes such as 1C1C and 1C2C, and control-only codes such as 1C31. F1-5 and F1-8 name both parts at once.
The reset
Switch the range off at its breaker for one minute, then switch it on. Look at the display for the next minute for F1-5 or F1-8. Finally, check that the range operates properly.
After the reset
If the display stays clear, JennAir asks nothing more. If a code returns, three locations remain possible, and telling them apart needs testing that the page does not leave to owners.
When a code returns
JennAir gives no more owner advice. A technician must separate the control from the keypad and the wiring. Notice whether the keys responded before the code showed; JennAir does not request it, but it is a useful detail to pass on.
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
