Broil Valve Testing

Test points
Broil Valve
The broil valve supplies the gas flow to the burners
to allow ignition. As voltage is applied to the
bake igniter, the resistance begins to drop. As the
resistance drops, current flow through the gas valve
is increased. This increased current flow allows the
gas valve to open and gas to flow to the igniter.
Once the gas comes in contact with the hot igniter,
ignition occurs.
To access the dual bake valve, remove the unit from
installation. Remove screws securing the access
panel on the right side. The broil valve is now
accessible.
With Volt-Ohm meter set for resistance, measure
the broil valve resistance. The valve should measure
approximately 1.2 Ω from W-BK. Current flow
through the gas valve should be 3.2 – 3.6 Amps.
Voltage to the valve is 3.2 – 3.6. Applying voltage
above this range to the valve can cause damage to
the valve.
