Service Manual 599337A: 302B Series Titan Oven
5.26 Determining which power module is faulty in a double oven
(F4 or F5 Fault Codes)
(Refer to Technical Overview Section 2.25)
Set up the double oven as if it were a single oven so that the faulty power module can
be eliminated.
PROCEDURE:
For Upper Cavity power module:
1. Unplug the purple harness from the clock module.
2. Remove the link harness to the lower cavity power module.
The clock module now assumes there is only one power module. The second
power module will run in a powered but disabled mode (elements will not operate).
3. Try to operate the upper cavity. If the fault code reappears then the upper cavity
power module is faulty and needs to be replaced. (refer to Servicing Instructions
Section 7.9)
If the fault code does not reappear, then the lower power module is faulty and needs
to be replaced.
