In brief
Jenn-Air documents F6 as the oven being unable to carry out the function you selected, with the relay control board or its wiring as the suspects. Do not keep retrying the function: switch the oven off at the breaker, reset it once, and use it only if the function then runs normally.
Error codes
Reference| Code | Meaning |
|---|---|
| F6 | The oven could not execute the function. There may a problem with the Relay Control Board, or the associated wiring. |
What you observe
- The failure is occasional — The same function works most days and fails on others with the code.
- A click with no heat afterwards — A relay can be heard switching, but no element warms and the cavity stays cold.
- NEAR MISS: the function runs but the temperature is wrong — That is a regulation or sensor question, not a function the oven failed to execute.
Likely causes, ranked
- A worn relay on the relay control board — Ranked first when F6 comes and goes on the same function: a relay whose contacts are pitted closes on some starts and not on others.
- An open wire or burnt terminal between the board and the load — High-current wiring to the elements runs hot; a terminal that has burnt or a wire that has opened stops the function as surely as a failed relay.
- A latched fault from a supply disturbance — A brief outage mid-function can leave the control holding the code; a clean power cycle clears that and nothing else.
Diagnostic order, cheapest and safest first
- Find which functions raise the code — Try bake, broil and any convection or clean mode in turn, briefly, and note which ones fail. One failing function and several are different faults.
- Reset at the breaker — One clean power cycle shows whether the code is latched from a disturbance or live.
- Listen for the relay click — A click when the function starts means the board is trying; no click points further upstream.
Clearing the code and safe checks
- Record the result — Note which function failed, at what point and whether a click was heard. That record saves diagnostic time.
Tools: notebook or phoneAbout 5 min
- Reset the control — Switch the oven off at its breaker, wait a few minutes, and switch it back on.
About 5 min
- Stop before any panel comes off — Everything past this point needs live measurements or a panel removed; that is the line between an owner check and a service call.
Safety first
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. The wiring between the relay board and the elements carries heavy current and runs hot; a burnt terminal can arc when disturbed.
When it is a service call
If F6 returns on the same function after a power cycle, the next step is a technician: the relay, the wiring and the element or fan it drives all need testing under power to find which one stops the function.

Scope of this code reading
Generalized information: F6 is read here for the Jenn-Air oven line as a whole, which fits Jenn-Air ovens whose code list carries F6 as a function the oven could not execute, with the relay control board named. It is not a reading for Jenn-Air cooktops, hoods, or models whose documentation reads F6 differently. Model lines can reuse a code with another meaning, so a model-specific page, where one exists, comes first.
