GE FTP18 Doesn't work at all, Shows an error code of F9 and periodically beeps for an extended time

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.

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

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.

F9-- Failed Lock switch detected.

Check wiring to door lock switch (the wire harness may be connected wrong). Check for stuck lock switch.

If the wires are ok and, the switch is not stuck, replace it asap.

oven door will not close tight - what is wrong

you can also put a piece of paper between the ribbon cable where it joins up before the connector. It has been reported that the cable will short in this area. Try that before spending more money since most of the F-codes appear to be cable related.

short inthe key pad, thinks a button is being preesed for an extended period of time youll need to replace the keypad/ electronic control

Here's what F9 code means:
1. Door lock safety circuit on ERC sensed Replace the door latch assembly
2. Door Lock Warning Check door lock circuit or Replace Clock
Try pressing and holding the door latch to unlock position and then press cancel for a few seconds. The latch should return to its original position.

The F9 error message usually means that the oven temperature is above 600 degrees F. Check that the fan is operating. Make sure that it is not blocked. Make sure the vent areas are not blocked. There could also be a welded relay contact or high resistance in the oven sensor leads or connections.
