WARNING
145. THERMAL FUSE (Electric Models)
a. While supporting the access panel, remove two
screws from bottom edge of front access panel.
Refer to Figure 40.
b. Gently lower the access panel to disengage
panel locators from bottom edge of front panel.
Refer to Figure 48.
c. Label and disconnect wires from thermal fuse.
Refer to Figure 52.
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.
146. HEATER ASSEMBLY (Electric Models)
a. While supporting the access panel, remove two
screws from bottom edge of access panel. Refer
to Figure 40.
b. Gently lower the access panel to disengage
panel locators from bottom edge of front panel.
Refer to Figure 48.
c. Disconnect wires from heater assembly. Refer
to Figure 52.
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). Refer to
Figure 52.
147. CYCLING OR LIMIT THERMOSTAT
a. While supporting the access panel, remove two
screws from bottom edge of access panel. Refer
to Figure 40.
b. Gently lower the access panel to disengage
