Dryer Troubleshooting
Gas Dryers
1. Remove any damp clothing from the dryer.
2. Set the timer to an Automatic cycle. Set fabric
selector switch to Regular.
3. Remove the top 3 screws holding the control
hood to the rear panel.
4. Start dryer by pushing in timer knob.
5. Using a volt/ohm meter set to AC voltage,
measure the voltage across terminal “T” and
terminal “N” on timer. Refer to Figure 4.
6. Meter should read no voltage when the unit is
first started and the dryer is still heating.
Continue to monitor these points until the burner
has shut off (this will take several minutes even
with an empty load). When the burner shuts off,
meter should read 120 Volts and the timer motor
should advance the cycle.
7. If voltage is present, but the timer does not
advance, replace timer.
8. If meter does not read voltage, check the wiring
continuity using ohm scale on meter. UNPLUG
dryer. Remove Red/Black striped wire from
terminal “T” on timer and perform an ohms
check between the timer wire and the cycling
thermostat terminal, where the Red/Black stripe
wire attaches on the cycling thermostat (located
on the blower assembly). If the wire shows
continuity, reattach the wire on terminal “T” of
timer. Replace cycling thermostat and check for
proper operation.
