Whirlpool electric range Super capacity 465 has the lock stuck in locked position. Door is open, but the lock won't retract! It keeps flashing F530 message and won't stop beeping!!

your latch is defective. they have parts that melt when you use the self cleaning cycle. they also just go out. the door should auto latch when you start the cycle but it times out when it is not seen.

Same thing happened to me about 1 month ago... Did you get some kind of power outage or lightning strike??? I am pretty sure the stove part works but the oven doesn't right?!?! It might be 2 things.. Either the temperature sensor inside the oven doesn't work or it's the control board (where the clock is). I tried to chaned teh temp sensor but it did not work. I then changed the Control Board and oven works again...

I had the same FSE error which the whirpool web site advises that you will need to schedule a service appt to fix. Instead I leaded against the door while initiating the cleaning cycle and the door locks and oven cleans fine.

Hi, Try setting it to clean, then cancel the clean cycle right away. Sometimes this helps. Please let me know.
Thanks

there are 3 screws under the front of the top with the oven door open actually there are 6 screws but only 3 you need to remove to raise the glass top up!! to service the burners
