Gas Valve Removal
1. Ensure electric to the dryer has been
disconnected.
2.
Ensure the gas is turned off at the supply.
3. Disconnect the house supply line from the
dryer.
4. Disconnect the harness connectors from the
gas valve.
5. Remove three 1/4-inch hex-head screws from
the bottom side of the gas valve bracket.
6. Lift the gas valve along with the black pipe
going to the valve up and away from the
bracket.
Radiant Sensor (Flame Detector)
The radiant sensor (flame detector) is attached
to the right side of the combustion chamber. The
radiant sensor is used in gas dryers to ensure
the igniter is hot enough to ignite gas once it
is released from the valve. When the radiant
sensor is cool it is closed. This allows electricity
to energize the dryer's igniter. After the radiant
sensor heats up, because of its close proximity to
the igniter, it opens. The power is then diverted to
the valve solenoids where the valve should open
and release gas. The radiant sensor rarely goes
bad.
Radiant Sensor Diagnosing
1. Support the switch's terminals with a pair of
needle-nose pliers while disconnecting the
two connecting wires.
2. Check for continuity across the switch's
terminals. There should be no resistance
measured when the dryer is cool.
If the igniter heats up but never clicks off, replace
this switch.
Radiant Sensor Removal
1. Remove the drum (see
Drum
section).
2.
Disconnect the two wires from the flame
detector.
3. Remove the Phillips-head screw that
holds the flame detector to the combustion
chamber.
