1. While supporting the access panel, remove two screws from
bottom edge of access panel.
2. Gently lower the access panel to disengage locators from bot-
tom edge of front panel.
3. Close main gas shut-off valve. Refer to
.
4. Remove wires from sensor terminals.
5. Set test meter to read Ohms and put meter probes on the
ground wire connection in 12-pin block (connected to mod-
ule) and on the green ground screw in base of dryer.
6. Meter should read “zero” Ohms. If meter registers an Ohm
reading of any amount, check ground wire connection and re-
place as necessary.
Thermal Fuse (Electric Models)
1. While supporting the access panel, remove two screws from
bottom edge of front access panel.
2. Gently lower the access panel to disengage panel locators
from bottom edge of front panel.
3. Label and disconnect wires from thermal fuse.
NOTE: Refer to wiring diagram when rewiring ther-
mal fuse.
4. 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.
Heater Assembly (Electric Models)
1. While supporting the access panel, remove two screws from
bottom edge of access panel.
2. Gently lower the access panel to disengage panel locators
from bottom edge of front panel.
3. Disconnect wires from heater assembly.
NOTE: Refer to wiring diagram when rewiring heater
assembly.
4. Set meter to read Ohms. Apply meter probes to the heater as-
sembly terminals. Meter should read as follows: (Cold
Ohms).

Cycling or Limit Thermostat
1. While supporting the access panel, remove two screws from
bottom edge of access panel.
2. Gently lower the access panel to disengage panel locators
from bottom edge of front panel.
3. Label and disconnect wires from thermostat.
NOTE: Refer to wiring diagram when rewiring ther-
mostat.
4.
Cycling Thermostat (S.P.S.T. – 2 Terminals) or Limit
Thermostat
a. Set meter to read Ohms.
b. Apply meter probes to the thermostat terminals.
c. Meter should read “zero.”
5.
Cycling Thermostat (S.P.D.T. – 3 Terminals)
a. Set meter to read Ohms.
b. Apply meter probes to terminals 1 and 3. Meter should
read “zero”.
c. Remove screws holding thermostat to blower fan cover.
d. 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”.
Door Switch
1. While supporting the access panel, remove two screws from
bottom edge of access panel.
2. Gently lower the access panel to disengage locators from bot-
tom edge of front panel.
3. Remove two screws holding bottom tabs on front panel to
dryer side panels. Swing bottom of front panel away from
dryer far enough to disengage hold-down clips and locators
from cabinet top.
4. Disconnect wires from door switch.
NOTE: Refer to model wiring diagram when rewiring
door switch.
5. Set meter to read Ohms and apply meter probes on switch ter-
minals 1 and 3 with door closed. You should get “zero” read-
ing.
