GE Monogram wall oven model ZET938sfss shows F9 error code

The wall oven probably has a bad door lock. If the door is stuck shut, average repair cost ~ 300 dollars - 500 Dollars max. Worth calling service if you lack the confidence or experiece to tackle this expensive machine. If the wall oven door actually opens and isn't locked shut, try holding down the door switches to see if you get a response or if the error clears. Recommend calling GE service for this repair if available in your area. 1800 GE CARES

An F9 error code on a General Electric (GE) oven indicates that the oven's electronic control system has detected a problem with the automatic door lock. The automatic door lock mechanism prevents the oven door from being opened when the oven is set for "Clean" mode. The malfunction may be a jammed door lock mechanism, a pinched or broken wire, a faulty lock switch or a fault in the control board itself

F9 is a problem with the oven door lock circuit. If the door is locked, it's probably a bad switch that tells the oven it's locked. If the door isn't locked, it's probably a problem with the lock mechanism.

A common problem on many built-in GE ovens (you don't say if yours is built-in or free standing...) is air circulation in the control panel. The fan that keeps the panel cool either stops working or gets clogged with dirt/dust and can't move any air. This causes the panel to overheat and can cause all kinds of odd problems and error codes. If you have a built-in, check to make sure the fan is working and the mesh screen behind it is clean.

Shut off the circuit breaker to it for FIVE minutes, then back on. If the problem persists then do the following:

A latch locks the center top INSIDE of the door during cleaning.
Run a piece of semi-stiff, flat object, like a cardboard strip that is in L shape behind the top lip of the door from RIGHT TO LEFT. You may need to push it along with your finger jambed in there when it reaches the latch. With a little push the latch should open.

Try to run the oven, if F9 shows again, press cancel Oven to quiet it. The Lock state is still in place. Move the latch hook manually all the way to RIGHT. Then shut off the circuit breaker for FIVE minutes, then back on. The oven should work ok.

If this fails again try the five minute shut off with the latch in other starting positions.

If none of these work then the latch mechanism, or it's motor is really broken. Replace or ditch and never buy Amana again!

Hi

Thanks for using FixYa. F9 error in your oven/range indicates an issue with the door locks assembly and/or the door latch. To start with check the door lock circuit, you can also try to jump start it to see if it's working. If it's not working then the Electronic Range control has gone bad and should be replaced, if it is working then the door lock circuit should be replaced. Please do rate the solution if the issue is resolved or post a comment for further assistance.

Thanks

Hello,F9 error means there is a problem with the lock switch.Check the wiring to the door lock switch (the wire harness may be connected wrongly).Check for stuck lock switch.
Thanks

Disconnect power to the oven.
Open the oven door. Remove three screws from underneath the oven's control panel. Lift the control panel straight up to disengage the mounting pins on the top corners of the panel, then tip the panel toward you.
Inspect the door lock mechanism. The mechanism is in the lower left area of the space behind the control panel. Rotate the cam on the door lock mechanism to be certain it moves without binding. Replace the mechanism if its mechanical parts do not function properly.
Inspect the wires that connect the door lock mechanism to the control panel. Check for pinched or broken wires. Check for wires with frayed insulation. Repair wires as needed if defects are present.
Locate the six-pin connector on the door lock motor on the right end of the door lock mechanism.
Rotate the cam on the door lock mechanism to the unlocked position. Test the resistance between Pin 3 and Pin 1 of the door lock connector with the ohmmeter. The resistance should be 0. Replace Lock Switch 2 of the door lock mechanism if the resistance reads other than 0.
Rotate the cam on the door lock mechanism to the locked position. Test the resistance between Pin 3 and Pin 2 of the door lock connector with the ohmmeter. The resistance should be 0. Replace Lock Switch 1 of the door lock mechanism if the resistance reads other than 0.
Contact a certified GE appliance repair facility if the source of the F9 code has not been discovered. Troubleshooting the oven with the electric power turned on is a job for a certified technician.

This is a lock switch error code. Check wiring to door lock switch (the wire harness may be connected wrong). Check for stuck lock switch. If the switch cannot be re adjusted, it must be replaced.

The F9 code indicates there is a problem with the door lock.

Try disconnecting the power to the range for 10 seconds and reconnecting. Open the oven door and hold the door switch plunger in while you try these things. Put the control into clean for 5 minutes then cancel clean. You must hold the door switch plunger in for the 5 minutes.

Try canceling the clean cycle without putting the control into clean.

My oven was locked and would not open. No lock light was on but the oven was clearly locked. F9 error when I hit certain buttons.

Try this. I unplugged the oven for about 5 minutes. Plugged back in. A LOCK light came on. Held down "Oven Cancel" for a few seconds. Door opened and lock light went off. No more F9 error when I hit those buttons.
