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 disconnected.
"E-08" will show on the display if
within 10 minutes at room
temperature.
Make sure the harness connections
at the PCB terminals (T02, T03) have
not come loose or disconnected.
Make sure the broil and bake burners
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.
*
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.
*
oven temperature sensor and harness are
working and connected properly, replace the
PCB.
* Measure the oven temperature sensor
temperature). Replace a faulty oven
temperature sensor.
* Repair or replace the harness.
* Open or close the air shutter at the base of
