Hello
have you run the unit through diagnostics ? Run the unit through diagnostics and see if there are any stored error codes. see compete troubleshooting guide links below. Matt Ace technician

To Enter Diagnostics Mode:
Before proceeding with any corrective action, perform the
following steps to enter the Diagnostics Mode.
1. Enter Diagnostics Mode by pressing
CANCEL>CANCEL>START.
2. If control does not enter Diagnostics, repeat Step 1.
3. From the Diagnostics Menu, it is possible to select one
of these options by pressing the left or right arrow key:
Error Codes: View the failure history
Relay Activation: Manually activate each relay
Model Select: Configure the product (combo)
Software Version: View the versions of software on
the product
Status Screen: View the traditional oven cavity
temperatures and door and latch switch status.

  • i ran diagnostics no codes. I also activaded relays for bake, broil and latch switch and worked. temperatures for bake and broil went up to around 400. But when i ran it on bake mode it would still fail. When i ran the relay activation on the broil it went to about 400 then i went to bake mode. After i switch to regular bake mode, temp started to drop slowly from 400.
