Broil Relay (Inner And Outer); Inner Broil Relay; Outer Broil Relay; Convection Element - Viking RDSCE2305B Service Manual

Troubleshooting
To avoid risk of electrical shock, personal injury, or death, disconnect electrical power source to unit, unless test
procedures require power to be connected. Discharge capacitor through a resistor before attempting to service.
Ensure all ground wires are connected before certifying unit as repaired and/or operational.

Broil Relay (Inner and Outer)

When a broil element is selected by the oven
control board, voltage is sent to the broil relay
coils. A red LED in front of each coil verifies
coil voltage is being sent to that particular
relay. This does not indicate however that
the relay is functioning. When the individual
element relays are energized, (L1-black)
power is sent through the relay to the broil
elements. (L2 power is controlled by the line
break relay.)

Inner Broil Relay

Select a cooking program. When the inner
relay contact is energized (red LED lit at base
of relay), check for 240 VAC between the
yellow wire at the line break relay and the
violet wire on P6. If 0 VAC is read, disconnect
power and remove the P6 Molex plug.
Reconnect power and using your ohmeter,
check for continuity between the two relay
contacts (refer to photo, above). If you read
infinite ohms (∞) when the relay is energized,
this indicates a faulty relay and you will need
to replace the control board. If you read 0
ohms, the relay contact is closing.

Outer Broil Relay

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

! WARNING
Reconnect power and using your Ohm meter,
check for continuity between the two relay
contacts (refer to photo, above). If you read
infinite ohms (∞) when the relay is energized,
this indicates a faulty relay and you will need
to replace the control board. If you read 0
ohms, 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.
