Troubleshooting
WARNING
To reduce the risk of electric shock, fire, explosion,
serious injury or death:
• Disconnect electric power to the dryer before
servicing.
• Close gas shut-of valve to gas dryer before serv-
icing.
• Never start the Dryer with any guards/panels re-
moved.
• Whenever ground wires are removed during serv-
icing, these ground wires must be reconnected to
ensure that the dryer is properly grounded.

IMPORTANT: Refer to wiring diagram for aid in testing
dryer components.
No Timer Advance in Automatic Cycles
For a description of Automatic drying feature, refer to How Your
Dryer Works . If dryer heats but the timer does not advance, per-
form the following service procedures:
Electric 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 volt-
age across terminal “T” and terminal “M” on timer. Refer to
Figure 2 .
6. Meter should read no voltage when the unit is first started and
the dryer is still heating. Continue to monitor these points un-
til the heating element has shut off (this will take several mi-
nutes even with an empty load). When the heating element
shuts off, meter should read 120 Volts and the timer motor
should advance the cycle.
7. If meter does not read 120 Volts after the unit has reached
proper operating temperature use meter to check for 120 AC
Voltage between terminal “A” and terminal “N” (neutral) on
the timer.
8. If voltage is present, recheck voltage between “T” and “M”.
9. If voltage is present, but timer does not advance, replace tim-
er.
10. If meter does not read 120 Volts at “A” and “N”, check the
wire connections at the heating element and timer (blue/black
wire). If the connections are good, UNPLUG dryer, remove
wire at terminal “A” on timer and perform an ohms check on
wire continuity between the heating element and timer. If the
wire shows continuity, replace timer.
