Miele double oven. The smaller lower oven takes about 25% longer to heat up then the larger upper oven does. What to do?

cdkd, there should be a TC0, on the back of the oven. Thermal cut out. You want to check to see if it is open. You will have to pull the oven out enough that you can remove the back panel cover and check it. The lower and upper oven should have one. It's a very cheap part to replace. If this TCO fails, no heat. Check this first before buying a new board. Catriver..post back.

On my double oven the bottom door was not closing by at least 21/2 inches the upper door would allow the light to stay on . Upon close examination this problem appeared to be the door was too low which did not allow the gasket to seat in the oven cavity, holding the door open. new hinges and receptors did not resolve this condition.This is how I corrected this condition. 1 open the doors one at a time and lock the hinges.2 remove the doors from the receptors (be careful they are heavy) and set aside. 3 remove mounting screws holding oven in cabinet. 4 slide oven forward enough to hold onto receptor sockets on left and right sides lower and upper 5 remove receptor sockets by removing the screws in front of oven(be careful to hold on to the receptor so it doesnt fall behind oven into cabinet)7 with a center punch punch a start point 1/8 inch above the existing screw holes and drill appropriate size hole for screw THE HOLES MUST MATCH UPPER AND LOWER RECEPTOR OR THE SCREWS ON THE LOWER DOOR WILL SCRATCH THE UPPER DOOR .8 attach receptors to oven in new holes 9 slide oven back into cabinet and replace screws removed in step three 10 attach doors into receptors and push locks forward into receptor cavity attach lower door first and check for operation then upper door open slowly and check enough clearance exists for the screws on the lower door miss the upper door . If more clearance is needed elongate the holes drilled earlier(repeat steps 1 through 5) and slide receptor up on upper door. NOTE The receptors are not in a sealed space in the oven cavity and are not exposed to any heat. Periodically check the screws for tightness. After performing this procedure Both doors close all the way and the light is no longer a problem Now 20 minutes cook time MEANS 20 MINUTES COOK TIME.
HOPE THIS RESOLVES YOUR PROBLEM !!!!!

I had the same problem after auto-cleaning my oven just before Thanksgiving. The cause was overheating...and the tripping of a heat sensor switch.

The switch (reset button) is located about 3 inches behind the door locking mechanism.

Removing the front panel (4 screws) that the door lock sticks through exposes the switch. Just push the little red button & your are back in business!!

I Have worked on quite a few of these in the last few weeks, i have found that about 50% of these problems are caused by the control board and the other 50% caused by the thermal fuse, you can check the fuse by removing the unit from the wall and checking for continuity at the thermal fuse. If the fuse is in fact ok then it is the board that is not sending the correct amount of power to the elements. So the Power Control Board is what will need to be replaced, you can purchase both of these parts at, http://www.reliableparts.com/ by using your model number.

Please rate my solution if it was helpful to you.

If you need more in depth information or pictures on how to remove and take this machine apart, feel free to ask.
