F8 is an automatic shutoff after a cooking area ran too long. Cool the area, reset the breaker, and check.
Model compatibility: JennAir reuses codes across series and model years, so F8 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
F8 means a surface cooking area was in operation too long and the automatic shutoff activated.
JennAir lists F8 for both its electric and induction cooktops. The code means that a surface cooking area was running for too long and the automatic shutoff took over. The manufacturer’s tone is calm, and what you are seeing is a shutoff and not a fault report.
Why the cooktop does this
The page says only that the cooking area was in operation too long and so the automatic shutoff activated. A timed cutoff of this kind is generally a safeguard against leaving a cooking area on without attention. No failed component is named for F8, and no number of hours is given, so none is stated here.
Steps from JennAir
Switch off the surface cooking area that was in use.
Remove any cookware from that area and give it time to cool.
Turn the cooktop’s circuit breaker(s) off and leave them off for one minute.
Turn the breaker(s) on again.
Monitor the cooktop for one minute and make sure F8 does not return.
Check that the cooktop operates normally again.
Once the reset is done
A cooktop that heats normally, with the code staying away through the minute of watching, needs nothing more. If F8 returns right after the reset, or the cooktop does not respond at all, you have used up the owner steps. JennAir lists nothing further, and the next move is a service visit instead of cycling the breaker again and again. Leave the cooktop off, with no pans on it, in the meantime.
Codes close to F8
F2 is triggered by a surface cooking area being too hot, not by time.
F4 relates to a pot or pan sitting too near the control panel.
When F8 keeps coming back despite the cool-down and reset, phone (310) 622-9465 about JennAir cooktop service in Los Angeles. Have ready the code, whether the cooktop is electric or induction, and the fact that you did the one-minute breaker reset. The cooktop and rangetop repair page gives more.
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.
