Heater Assembly
WARNING: Sharp edges may be exposed when
servicing the heater. Use caution to avoid injury.
Wear Kevlar gloves or equivalent protection.
The heater assembly is located on the back of the
cabinet. It consists of 2 ribbon elements fastened
to a single housing, auto reset thermostat, and
manual reset thermostat. The thermostats are not
replaceable. It is necessary to replace the heater
assembly when an open thermostat is detected.
Both elements, heater1 and heater2, are controlled
by relays on the control board. Heater1, rated at
1600 W, draws approximately 7 amps at 240 VAC
and has an approximate resistance value of 34
Heater2, rated at 600 W, draws approximately
2.5 amps at 240 VAC and has an approximate
resistance value of 92 .
Both heaters can be checked from CN2 pin 2 (black) to
RY5 (red) for the approximate resistance value of 126 Ω.
The heaters can be checked individually for confi r-
mation at the heater connecter. The approximate
resistance values from gray to brown is 34 and
from gray to black is 92 .
Operation of the heater assembly can be checked by
using the service test mode. (See
Service Test Mode.)
To access the heater assembly, it is necessary to
remove the top and back cover. (See Top Cover and
Back Cover.)
To remove the heater assembly:
1. Remove the top and back cover. (See
Top Cover
and Back Cover.)
Auto Reset Thermostat
The auto reset thermostat is attached to the top of
the heater assembly and located to the left of the
manual reset thermostat, as viewed from the back
of the dryer. Two gray wires are connected to the
auto reset thermostat. The thermostat monitors
incoming air temperature.
If the thermostat reaches a temperature beyond its
maximum temperature rating, it will trip and disable
power to the heaters.
The auto reset thermostat opens at 212°F (100°C)
and will automatically reset at 176°F (80°C).
The auto reset thermostat is not available as a
separate part. To replace the auto reset thermostat,
it is necessary to replace the heater assembly. (See
Heater Assembly.)
