DIAGNOSIS
Make sure the door lockout feature
is not turned on.
Check for a burned out bulb.
Check the harness connections,
the oven lamp relay (RY06), and the
source control relay (RY01).
Measure the resistance across
the light ballast/socket terminals.
(Normal : ∞)
This is normal.
Check the membrane control
harness and connectors (CN08)
on the PCB and membrane control
panel.
LED display is inferior.
Check to see if the sabbath function
has been turned on.
The buzzer does not work on the
PCB.
* Unlock the controls by pressing and
holding the lock key for 3 or more
seconds.
* Replace with a 40 watt appliance bulb.
* Repair or replace loose or disconnected
harness.
* Replace any malfunctioning relays.
* Replace the light ballast/socket.
* Replace the PCB.
* The insulation around the oven will give off
a slight odor until the adhesive has cured.
This should go away after the first couple of
oven uses.
* The oven is designed to burn off dirt and/or
foreign substances.
*
If the oven is dirty, run a self-cleaning cycle.
(See page 53 in the "User Manual".) A
ventilation system should be used while the
oven is self cleaning.
* Reconnect securely or replace a damaged
membrane control harness.
* Replace the PCB assembly.
(PCB and membrane control panel.)
* Press and hold the Sabbath pad for at least
3 seconds. The display will show the time of
