Used my wall oven today to bake bread at 450. After the loaf finished I turned off and propped the door open to cool. When I returned about 10 mins later the front display is off and no light when opening oven. Checked breakers and reset - no change. Prior to this, the oven was having problems with maintaining heat after preheat off by 25-30 degrees after reaching target temp. If we turned bake off and back on it would begin heating again until it reached the temp setting, then start dropping again. What should I check?

I'm attaching your tech. data sheet below.

On page 2 Get into Enter Diagnostics Mode and tell us what it says in TEST MODE.

Then on Page 4 DO--->General Procedure: Auto Test Mode

Tell us what error code you get.

HI Jake - sorry wasn't more clear. The oven has a blank control panel and no power so cannot enter diagnostics mode. Oven light is off so thinking a fuse may have blown?

Got it!

Then it sounds like the thermal fuse went out.

Here's the thermal fuse for your model:
Thermal Fuse WPW10545255


I'd ohm test it for continuity with a multimeter?

This video shows you how: Thermal Fuse Test Video

Disconnect power to your oven first before accessing it and ohm testing it.

This video gives you the general idea of the location of it and how to access it:

Continuity test on the thermal fuse shows it's blown. Got the replacement part ordered and will follow up after repair.
