I have a customer with a GE Wall Oven
It's got me stumped.
The symptom is that the oven undercooks.
Even a frozen pizza will not be cooked in the allotted time required (after the oven has been Preheated)
I checked the PreHeat temperature rise with a digital temperature tester and it passed that test
Replaced the Oven Sensor---no success.
Both elements function perfectly (alternating between bake and broil during PreHeat)
I'm thinking a faulty Electronic Oven Control
What do the GE gurus think ?
