Determining Which Power Module Is Faulty In A Double Oven (F4 Or F5 Fault Codes) - Fisher & Paykel Titan Aerotech OD302US Service Manual

Service Manual 546596A: 302 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)
For US products only
If the fault code does not reappear, then the lower power module is faulty and needs
to be replaced.
For NZ/AUS and EU products only
If the fault code does not reappear, check the lower power module for faults.
1. Disconnect the clock module from the upper cavity power module at the power
module end of the black 12 way harness.
2. Disconnect the link harness between the upper and lower cavity power modules.
3. Plug the clock module harness into the link harness connection on the lower cavity
power module.
4. Try to operate the lower cavity using the upper cavity controls.
If the fault code reappears then the lower cavity power module is faulty and needs to
be replaced. (refer to Servicing Instructions Section 7.9)
