Oven lock will not unlock

The F90 error code indicates that the door unlock time exceeded. This will happen if the lock is in the locked position with the oven door open or if the lock motor fails. Have someone hold in the oven door light switch while you set the control up for the self-cleaning cycle. Let the self-cleaning cycle run for only 4-5 minutes then press stop/cancel. This should allow the lock assembly to reset & retract the door lock back into the unlocked position.

You can also try resetting the appliance by disconnecting it from the outlet or switch off the circuit breaker for 20-30 minutes. Once power is restored run a test cycle. If this does not work I suspect a door lock assembly failure. This type of diagnosing will require accessing the lock assembly & using a volt/ohm meter for testing

if you look around under the handle or under the top of the stove on the front there should be thin lever. This lever is designed to lock the oven door closed tightly when you are activating the self cleaning oven feature. It is likely that someone accidentally lock the lever while the door to the oven was open. Simply find that locking lever return it to the unlocked position and your door should shut fine.

To Unlock the hinge on an Ariston Oven Door

Lay the oven door flat on the worktop with the inner door upwards and the locked hinge facing you.

With a pair of pliers and a good grip on the hinge, force the locked hinge towards you (by pulling it open towards you) and keep it in position by flipping the U piece over.

Fitting the Oven Door

Fit the door to the oven with the metal receivers in the slots on the oven.

Once the receivers are in the slot, fully open the door (in a downward position).

Flip the U shaped pieces over to lock the hinges.

There is a pin that tells the oven the door is open, you need to push it in an hold it. It is pretty stiff, you can't use your bear hand. It will be in the upper left of where the door closes.

hold down the stop/clear button for 3+ seconds

I had the same problem. Open the oven door. Press and hold the light switch. You will hear the door lock move back into the correct position. Hope this fixes your problem. This has happened to me twice and holding the light switch always works.

On many freestanding stoves the lock motor is located in the right rear (looking from the front) with a long rod connected to the lock. Pull or push the rod to move the lock to the open position..

I had the same problem on my Kenmore Electric Range. Door would not unlock. Tried pressing "Off" for multiple seconds, but still would not unlock. No error codes. Clock was displaying normally. Finally decided to try running it thru the self cleaning operation to get it to cycle thru locking and unlocking the door. When I started self clean, the door automatically went thru the auto lock and "locked" appeared in the display. I then hit "Off" to clear it and stop the cleaning cycle. The door then unlocked as normal!

The problem may very well be in one of the micro switches on the self cleaning motor bracket. These switches control the electrical flow to the heating elements. In the owners manual there is/should be a chart that lists the unlock and safety combinations. This would be your best source of information.

Hold the lock button for 3-5 seconds...
