I have a frigidaire GLE7378ASG. I've had this oven for about 4 years. The display was replaced about a year or two after it was purchased. I'm glad I got the extended warranty from Best Buy because the replacement of the display paid for it.


Lately, my wife noticed that it takes a long time to bake cookies. It normally takes about 15 minutes. When she noticed it was not cooking, she used speed bake for about 3 minutes. Could there something wrong with it?

Use an oven thermometer and check the oven temperature. You may need a new senser.

so it's probably not maintaining the temperature?

That's correct, the oven is probably not getting up to temperature.

will this work?

Get one of those $3 ones at your local grocery store. They're acurate enough for this purpose. I think the temperature is off by more than 100 degrees

Here's the type I use, its very accurate and a little cheaper than that one you linked to.

I found trhe cheap one...

I had to set the temp at 390 to maintain 375. So it was off by about 15.

I have extended warranty on the oven, will this be covered even though the temperature difference is small?

The oven control comes with a calibration program to raise or lower the temperature via electronic offset.
It will be explained in the owners manual, but I think all you have to do is set it for 550, hold bake for a few seconds, and then use arrow up or down to alter it.
Depending on who BB sends, they may just adjust it accordingly.

What's the acuracy of that one? Does it say + or - so many degrees.
