Broil Relay (Inner and Outer)

When a broil element is selected, voltage is sent
to the broil relay coils. A red LED (D25 and D27) in
front of the respective relay verifies coil voltage is
being sent to that particular relay. This means that
12 VDC is being sent to the relay coil. It does not
indicate that the relay contacts are closing. When
the individual element relays are energized, power
(L1-black) is sent through the relay to the broil
elements. Power (L2-red) is supplied from the line
break relay).

Inner Broil Relay

Select a cooking program. When the inner relay
contact is energized (D25 LED at base of relay
illuminates red), check for 240 VAC between the
yellow wire at the line break relay and the violet
wire on P6. If 0 VAC is measured, disconnect power
and remove the P6 Molex plug.

Outer Broil Relay

contact is energized (D27 LED at base of relay
illuminates red),
check for 240 VAC

If 0 ohms are measured, the relay contact is closing.

Convection Element

Locate the P2 connector and the line break relay on
control board. The P2 connector will have a Molex
plug containing a white/red and black wire. The
white/red wire goes to the convection element and
the black wire is L1 input from main power supply.

Line Break Relay
With the power off and Molex connector removed
from the P2 control board connection, use an
Ohm meter to measure resistance between the
LED
white/red wire in the Molex plug and the yellow
wire at the line break relay. This will measure the
resistance of the convection element and should be
approximately 34.4
