TEST #4 Heater
This test is performed when either of the fol-
lowing situations occur:

Dryer does not heat

Heat will not shut off
This test checks the components making up
the heating circuit. The following items are
part of this system:
Harness/connection
Heater relay
Thermal cut-off
Inlet thermistor/high limit thermostat
Heat element assembly
Centrifugal switch
Exhaust thermistor
Machine control electronics. See ESD
information
User interface assembly
Dryer does not heat:
Locate the components using Figure 1 and
Figure 10.
SINGLE ELEMENT MODEL:
1.
Unplug dryer or disconnect power.
2.
Remove the front panel and drum assem-
bly to access the thermal components.
See Removing the Front Panel/Drum As-
sembly.
3.
Using an ohmmeter and referring to the
appropriate wiring diagram and strip cir-
cuit (see Section 7), measure the resis-
tance from the red wire at the thermal
cut-off to the red wire at the heater.
If the resistance is about 10 ohms, go
to step 5.
If an open circuit is detected, go to
step 4.

4.
Visually check the wire connections to
the thermal cut-off, high limit thermostat,
and heater. If connections look good,
check for continuity across each of these
components.
Replace the heater if it is electrically
open.
Replace both the thermal cut-off and
high limit thermostat if either one is
electrically open.
5.
If no open circuit is detected, remove the
P4 connector, then measure the resis-
tance between P4-3 (red wire) and P4-6
(red wire) at the connector. See Figure 16,
for connector location; and Accessing &
Removing the Electronic Assemblies.
If 5–15 k ohms are measured, replace
the machine control electronics.
If the resistance is less than 1 k ohm,
replace the thermistor.
