I did a self clean on my tappan electric oven; cant get the door to open.... what can i do?

MaryAnn, If you try to push the locking lever/handle towards the "lock" position first, then pull it back towards the open position, it should unlock for you.

However if that doesn't work, you can turn off the breaker for the electric range, in most electric panels, it is marked as "Range" or "Stove" but is typically a double pole 50 Amp Breaker (It takes up 2 spaces). If you look at the handles of the breakers, you should be able to see the numbers "50" on the handle.

Once you turn off the power, you should be able to unlock the oven. Some ranges require that the power be on in order to unlock it, but first try to open it with the power turned off, and it that doesn't work, turn the breaker back on and the door should be able to be unlocked.

Remember that it will take a little bit of effort to get the door to unlock in some cases, so give it a good tug.

Hope you find this Very Helpful and best regards!
