JennAir Microwave F4E7 Error Code

With F4E7, JennAir puts an owner check ahead of the power reset. Its built-in microwave article lists three suspects: the microwave meat probe, the meat probe receptacle and the associated wiring.

Do the probe check before anything else

Make sure the microwave meat probe is pushed in firmly in its receptacle. A probe sitting loosely is the easiest thing to eliminate and the check is over in seconds.

Two probes, two resistance values

JennAir says the oven meat probe must not be used in the microwave, because the resistance values differ. On a unit with a conventional oven and a microwave, each probe belongs to its own cavity.

Then reset the power

1. Turn the circuit breaker(s) off and wait one minute.
2. Turn them back on.
3. Watch for a minute to be sure F4E7 stays away.
4. Test that the oven operates.

When F4E7 is back

A returning code means the probe, its socket or the wiring has to be tested. When you call, say whether you own just one probe or both kinds. Also note the order of events: whether the code cleared when the probe was seated or only after the reset. The probe check came first, so a clearing that needed the reset tells the technician something too.

• 3D31 and its group are oven meat probe codes with a fully seated check.
