Section 7 Test 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
69. THERMAL FUSE (Electric Models)
a. While supporting the access panel, remove two
screws from bottom edge of access panel. See
Figure 7.
b. Gently lower the access panel to disengage
locators from bottom edge of front panel. See
Figure 7.
c. Label and disconnect wires from thermal fuse.
See Figure 40.
NOTE: Refer to wiring diagram when rewiring
thermal fuse.
d. Set multimeter to read Ohms on the X1 scale.
Apply meter probes to the thermal fuse
terminals. Multimeter should read 0 Ohms. If
the meter does not show any reading (infinite
Ohms), then the fuse is open. If the fuse is open,
then replace BOTH the thermal fuse and the
limit thermostat.
70. HEATER ASSEMBLY (Electric Models)
a. While supporting the access panel, remove two
screws from bottom edge of access panel. See
Figure 7.
b. Gently lower the access panel to disengage
locators from bottom edge of front panel. See
Figure 7.
c. Disconnect wires from heater assembly. See
Figure 40.
NOTE: Refer to wiring diagram when rewiring
heater assembly.
d. Set meter to read Ohms. Apply meter probes to
the heater wire terminals. Meter should read as
follows: (Cold Ohms). See Figure 40.
71. CYCLING OR LIMIT THERMOSTAT
a. While supporting the access panel, remove two
screws from bottom edge of access panel. See
Figure 7.
b. Gently lower the access panel to disengage
locators from bottom edge of front panel. See
Figure 7.
c. Label and disconnect wires from thermostat.
See Figures 40 or 41.
NOTE: Refer to wiring diagram when rewiring
thermostat.
Cycling Thermostat (S.P.S.T. – 2 Terminals)
or Limit Thermostat
(1.) Set meter to read Ohms.
(2.) Apply meter probes to the thermostat
terminals.
(3.) Meter should read “zero”.
Cycling Thermostat (S.P.D.T. – 3 Terminals)
(1.) Set meter to read Ohms.
(2.) Apply meter probes to terminals 1 and 3.
Meter should read “zero”.
(3.) Remove screws holding thermostat to
exhaust fan cover.
(4.) Heat thermostat with a small flame until a
distinct “click” is heard, then immediately
apply meter probes to terminals 1 and 2.
Meter should read “zero”.
