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
52. BASE
a. While supporting the access panel, remove two
screws from bottom edge of access panel. See
Figure 6.
b. Gently lower the access panel to disengage
locators from bottom edge of front panel. See
Figure 13.
c. Remove two screws holding bottom tabs on
front panel to dryer side panels. See Figure 13.
Swing bottom of front panel away from dryer
far enough to disengage hold-down clips and
locators from cabinet top.
d. Disconnect wires from door switch. See
NOTE: Refer to wiring diagram when rewiring
switch.
e. Gas Models:
(1.) Silicon Carbide Ignition: 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 14.
Silicon Nitrate Ignition: Disconnect wire
harness from igniter and sensor assembly,
and from gas valve coil at disconnect
blocks. See Figure 15.
(2.) Close main gas shut-off valve.
(3.) Disconnect gas line to dryer.
(4.) Remove three screws holding gas valve
bracket to base and remove valve with
attached lead-in pipe. See Figure 17.
(5.) Remove screw holding burner tube in place
from right side of burner housing. See
Figure 17.
(6.) Gently move burner tube toward rear of
dryer to disengage tab from slot on left side
of burner housing. See Figure 17.
(7.) Carefully rotate burner tube and igniter
counterclockwise so tab is at the 8 o’clock
position, and CAREFULLY remove
burner tube and igniter assembly out
through front of dryer.
IMPORTANT: The igniter is very fragile. Be careful
not to damage it during removal.
(8.) Remove screw holding front of burner
housing to dryer base. See Figure 17.
(9.) Remove four screws holding shroud to
heater box and remove shroud and burner
housing out through front of dryer. See
Figure 15.
f. Electric Models:
(1.) Remove two screws holding element and
plate to heater box, then pull element down
and away from heater box. See Figure 17.
(2.) Disconnect wire harness from limit
thermostat, thermal fuse and/or heating
element. See Figure 17.
g. Open loading door and remove lint filter. See
h. Remove screws holding air duct to front
bulkhead and remove air duct. See Figure 19.
IMPORTANT: When reassembling, be sure seal on
exhaust fan cover makes airtight seal on flange of
duct. See Figure 18. If the seal is installed
improperly, the airflow through the exhaust system
will be restricted which can adversely affect dryer
performance.
i. Disconnect wires from thermostat (and heater,
if present) and remove ground screw. See
Figure 20.
NOTE: Refer to wiring diagram when rewiring
thermostat and heater.
To reduce the risk of serious injury or death
by carbon monoxide and other gases in gas
dryers, carefully read and follow all
instructions given in this section.
