Dryer Test Procedures
To reduce the risk of electric shock, fire, explosion, serious injury or death:
• Disconnect all electric power to the machine and accessories before servicing.
• Close gas shut-off valve to gas dryer before servicing.
• Never start machine with any guards/panels removed.
• Whenever ground wires are removed during servicing, these ground wires must be
reconnected to ensure that the machine is properly grounded.
• Washer motor not grounded! Disconnect electric power before servicing motor.

WARNING
46. Thermal Fuse (Electric Models)
a. While supporting the access panel, remove two
screws from bottom edge of front access panel.
b. Gently lower the access panel to disengage
panel locators from bottom edge of front panel.
c. Label and disconnect wires from thermal fuse.
NOTE: Refer to wiring diagram when rewiring
thermal fuse.
d. Set multimeter to read Ohms. Apply meter
probes to 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.
47. Heater Assembly (Electric
Models)
a. While supporting the access panel, remove two
screws from bottom edge of access panel.
b. Gently lower the access panel to disengage
panel locators from bottom edge of front panel.
c. Disconnect wires from heater assembly.
NOTE: Refer to wiring diagram when rewiring
heater assembly.
d. Set meter to read Ohms. Apply meter probes to
the heater assembly terminals. Meter should
read as follows: (Cold Ohms).
48. Cycling or Limit Thermostat
a. While supporting the access panel, remove two
screws from bottom edge of access panel.
b. Gently lower the access panel to disengage
panel locators from bottom edge of front panel.
c. Label and disconnect wires from thermostat.
NOTE: Refer to wiring diagram when rewiring
thermostat.
