No voltage.
Direct spark ignition module
defective.
Defective gas valve.
Gas turned off.
Defective door switch.

Check manual for proper leveling procedures.
Accidental damage to the fan blade can change the
dynamic balance. Damaged fans should be replaced.
Adjust basket clearance.
Tighten set screws. Make sure sheaves are in proper

Adjust belt tension.
Occasionally screws, nails, etc, will hang in the
basket perforations and drag against the sweep
sheets surrounding the basket. Such foreign objects
should be removed immediately.
Check for correct control voltage - 120V.
Check power supply, check secondary voltage on
transformer and check wiring and wiring diagram.
Replace direct spark ignition module.
Replace coil assembly.
Turn manual gas valve on.
Replace door switch.
Clean out lint compartment daily. Check back draft
damper for foreign objects, lint accumulation or
other causes that may prevent damper from opening.
Check duct work for lint build-up. Check installa-
tion sheet to insure that duct work and make-up air
openings are adequately sized. Check exhaust
outlet. If a screen has been improperly installed on
the outlet, it may be clogged with lint or frozen over
in winter. NEVER install a screen on the exhaust
outlet. Vacuum within dryer drops to .09 inches of
water column (.23 mbar), or less, for normal
operation of dryer. Vacuum reading (in inches of
water) should range between .15 (.38 mbar) and
.3 inches (.75 mbar). Vacuum reading can be made
with a vacuum U-gauge by removing a sheet metal
screw in the front panel of dryer and inserting the
rubber tube of the vacuum gauge into screw opening.
