Section 5 Service Procedures
To reduce the risk of electric shock, fire, explosion, serious injury or death:
• Disconnect electric power to the dryer(s) before servicing.
• Close gas shut-off valve to gas dryer(s) before servicing.
• Never start the dryer(s) with any guards/panels removed.
• Whenever ground wires are removed during servicing, these ground wires must be
reconnected to ensure that the dryer is properly grounded.

WARNING
IMPORTANT: When reassembling, be sure seal on
exhaust fan cover makes airtight seal on flange of
duct. See Figure 41. If the seal is installed
improperly, the airflow through the exhaust system
will be restricted which can adversely affect dryer
performance.
t. While supporting cylinder, carefully remove
belt, and remove cylinder out through front of
dryer.
IMPORTANT: Use care while removing igniter to
avoid damaging or breaking it. The igniter is very
fragile.
IMPORTANT: Handle igniter by grasping the
white ceramic portion of bracket only. DO NOT
handle silicone carbide or nitrate portion of igniter
with hands or allow any oil, grease or other foreign
material to contaminate it. Oil, grease and other
impurities or hairline cracks will cause the igniter to
burn out.
u. Gas Models with Silicon Carbide Ignition:
(1.) Disconnect igniter wires at disconnect
blocks, sensor wires from flame sensor
terminals, and wires from gas valve coils at
the quick disconnect blocks. See
Figure 40.
(2.) Remove screw from right side of burner
housing holding burner tube in place. See
Figure 40.
(3.) Gently move burner tube toward rear of
dryer to disengage tab from slot on left side
of burner housing. See Figure 40.
(4.) Carefully rotate burner tube and igniter
counterclockwise so tab is at the 8 o’clock
position.
(5.) Move air shutter end of burner tube slightly
to right and CAREFULLY remove burner
tube and igniter assembly out through front
of dryer. See Figure 40.
(6.) Remove screw holding burner housing to
heat shroud. See Figure 40.
(7.) Remove screw holding front of burner
housing to dryer base and remove housing
out through front of dryer. See Figure 40.
(8.) Remove four screws holding shroud to
heater duct. Remove shroud out through
front of dryer. See Figure 40.
v. Gas Models with Silicon Nitrate Ignition:
(1.) Remove wire harness from ignition
control.
(2.) Remove screws holding ignition control to
(3.) Carefully remove ignition control.
(4.) Remove wires from igniter and sensor
(5.) Remove screw holding burner tube to
burner housing. See Figure 40.
(6.) Remove screw holding burner housing to
(7.) Remove screw holding front of burner
housing to dryer base and remove housing
out through front of dryer. See Figure 40.
(8.) Remove four screws holding shroud to
heater duct. Remove shroud out through
front of dryer. See Figure 38.
w. Electric Models:
(1.) Remove two screws holding element and
plate to heater duct, then pull element
down and away from heater duct. See
Figure 40.
(2.) While supporting bulkhead, remove
screws holding bulkhead to rear of dryer
cabinet, and remove assembly out of dryer.
See Figure 53.
(3.) Remove screw holding exhaust duct to
dryer cabinet and pull duct out of cabinet.
See Figure 53.
(4.) Remove two screws from each rear cabinet
top hold-down bracket. See Figure 48.
(5.) Remove screw holding access plate and
remove plate.
(6.) Remove wire harness clips.
(7.) Remove locators and screws.
(8.) Remove two screws from front edge at
each side of cabinet. Then remove
remaining screws from around bottom of
cabinet and lift cabinet off base. See
Figure 48.
x. Remove leveling legs from base.
