JennAir JMV Code F6: relay control board could not run function

What F6 means

F6 on a JennAir over-the-range microwave hood, for instance the JMV9196CS or a JMV8000 series unit, says the oven could not execute the function. The guidance names the relay control board and its wiring. The microwave may stop heating, power off or refuse a new cycle. JennAir built-in microwaves show F6 for the oven control instead, so the model matters.

Common causes of F6

Relay control board is not switching correctly
Harness to the relay board is loose or burned
Board was damaged by a power surge

✓ One safe check you can try

1. Press Stop/Cancel first and leave the door open for a moment. 2. Flip the breaker off, count to sixty, and flip it on. 3. Check the display lights up normally. 4. Test with a cup of water for thirty seconds. 5. If F6 returns, stop using the unit and call us.

! Why to stop there

A relay board handles high current, so a bad one can scorch wiring.
Repeated resets stress the unit further.
Replacing the board needs the hood lowered, which takes two people.

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

F6F6 questions

What does a relay board do?

It switches power to the heating and fan parts on command from the control. When it cannot do that, the control reports F6 because the function you asked for did not happen.

Could F6 clear with a breaker reset?

It sometimes does after a surge. If it stays away, fine. If it returns within days, the board is likely failing and should be tested.

Is F6 related to F1E1?

Both name the relay control board on the hood, so the repair area overlaps. We read the unit's behavior and measure the board to confirm.
