HELP!

I moved into a new home and my wife noticed that her baked goods weren’t rising, and her food wasn’t cooking thoroughly or as quickly as it should.

I bought a Cooper oven thermometer (highly rated for accuracy) and found out that the oven was 75 degrees cooler than it should be on the center rack at 350 degrees. I used the control board to calibrate the temp up by 35 degrees (max allowable) and the oven is still off by about 40 to 50 degrees.

Then I bought a new sensor/thermostat (which goes toward the top of the oven) and there was no change.

I then decided to purchase a new control board (part #WB27T10807), installed it and the SAME exact problem.

Today, I took off the left panel and tested the continuity of the bake element, which was 20 ohms. I also checked voltage at the wire terminals to the bake element and it was 240+ volts.

What can I do next?? Is it possible that the bake element is not fully functioning? Can the sensor/thermostat at the top of the oven be sending the wrong ohm reading to the control board?

Please help. Thanks in advance!

OK, so I figured it out on my own. After staring at the back of the oven for a half hour and tracing wires, I noticed that the wire from the “BAKE” relay was going to the broil element and the wire from the “BROIL” relay was going to the bake element. Switched them and it worked!!

Now, unless the previous owner of our home tried to do some work on this appliance, that means that these wires were switched from the factory!! I took a picture of the control panel prior to replacing it or doing any work on it, and the wires were switched in the picture, so I know for sure it wasn’t my error.

Anyhow…hopefully anyone else with this mystery problem will benefit from this post.

Thanks all!
