DIAGNOSIS
Measure the input voltage at the
plug . (120VAC)
Measure the input voltage at terminal
T01 on the PCB .
Measure the voltage at the CN01
connector on the PCB . (L1~N:120VAC)
Make sure that the bake, broil, and
source control relays on the PCB are
working normally .
Make sure the harness connections at
the PCB terminals (T02, T03) have not
come loose or disconnected .
Measure the resistance between both
ends of the oven temperature sensor .
(normal : 1080 ohms)
Make sure the harness connections
at the PCB connector CN04 have not
come loose or are disconnected .
Make sure the harness connections at
the PCB terminals (T02, T03) have not
come loose or disconnected .
Make sure the broil and bake burners
have been adjusted properly .
Make sure the oven burner orifices
are sized properly for the type of gas
being used .
Make sure that the bake, broil, and
source control relays on the PCB are
working normally .
* Check the circuit breaker or fuse for the
range circuit .
* Make sure all wires are connected to the
PCB .
* Repair or replace the loose or disconnected
harness .
* Replace the PCB if a relay has been
damaged; relay is not working properly; or if
the PCB has a crack in it .
* Tighten or reconnect the PCB harness
connections .
* After confirming the harness has been
connected properly to the PCB, take the
following action:
- Repair of replace the harness .
- Replace the PCB .
* Replace the oven temperature sensor .
* Repair or replace the harness .
* If problem still exists after confirming the
oven temperature sensor and harness are
working and connected properly, replace the
PCB .
* Repair or replace the harness .
* Open or close the air shutter at the base of
the burners to optimize the flame pattern.
* Replace with properly sized orifices:
Burner
Orifice
Broil
Bake
NOTE: High-altitude orifice kits are available.
* Repair or replace the faulty relay .
* Make sure all harness connections are
properly connected .
* Replace the PCB .
