What does the F90 error code mean on my gas range?
The F90 error code indicates that the maximum oven door unlock time was exceeded. This can be caused by a failed door lock assembly, a wiring failure or a failed electronic oven control board.
Error codes can often be resolved by removing power to the appliance for a minute and then restoring the power.
Unplug the unit or turn the circuit breaker off for 60 seconds. Now, restore the power to the appliance by plugging it back in or turning the circuit breaker back on. Check to see if the error code is still displayed on the range.
If the error code is still displayed, then Professional service is needed.
: If the error code is not displayed after unplugging and plugging back in the appliance, test the appliance to make sure the error has been removed. Run the appliance in the cycle that initially caused the error.
