My electric Frigidaire "Elite" self-cleaning convection-oven stove just started to make noise as if a rotisserie was turning and I couldn't get the door open. Wife tried and door did open. Then we noticed that the lock bar that sticks out from the oven about an inch or so was slowly turning round and round, alternately locking and unlocking the door. Door is supposed to lock when you do the 2 hour self-clean program, but we didn't have that on. I took the oven fuse out to stop the process. How do I troubleshoot the lock? Thx.

Unplug the unit and open it go for the control panel where it located,under that is the circuit board is placed cleaned it by the using of contact cleaner.Its better you resolder all solder parts joint so the board will be in good condition. Possible defect in the control board panel is the circuit board such as a cold solder joint. A cold solder joint is where a lead of a component is not soldered at a high enough temperature and results in a bad electrical connection which can respond to physical shock and thermal stress.Due to time, heat, use, some solder joints would be cracked or loose. It is possible that the cold solder is still minimally connected (hanging by a thread). When the circuit board turns on heat would be generated which would be sufficient to further loosen up the solder joint to the point it no longer provides electrical contact. Jarring the unit creates movement inside enough to re establish the contact, sometime good enough sometimes not enough.A solder joint may also be broken or cracked because the unit is bang or hit. Look on the front and back of the board along the defective circuit to see any components that look like they are not soldered effectively or the solder connection is cracked or broken. A cold solder joint looks dull and/or bulging unlike the smooth and shiny normal solder joints. Then seeking a more experienced buddy for the soldering works might be your advantage. This is of course in addittion to possible electrical shock hazards when repairing..If you're not electrically experienced with troubleshooting electronics, I strongly suggest look for professional serviced or bring it a fined electronics shop...

Good luck:

This problem is caused by the control pad and circuit board behind it failing, replace the control pad. go here for parts.

Try these

1. Unplug the unit or shut off the circuit breaker for 5 minutes. Plug the unit back in or turn on the circuit breaker. Set the clock and gently try moving the door lock lever (is so equipped) or opening the door.
   
   
2. Set the self-clean cycle again and only allow it to work for 15 minutes. Cancel the self-clean cycle and allow the oven to cool. Gently try moving the door lock lever (is so equipped) or opening the door.
