Heater Assembly

WARNING: Sharp edges may be exposed when
servicing the dryer. Use caution to avoid injury.
Wear Kevlar gloves or equivalent protection.
The heater assembly is located behind the drum.
It consists of inner and outer open-wire elements,
each formed in a zigzag pattern fastened to a single
housing. The inner element consists of 2 elements
wired in parallel with each other and controlled
by a relay on the power board. The outer element
is controlled by a triac attached underneath the
support bracket.
When energized, the outer element draws
approximately 12.5 amps at 240 VAC. The outer
element has a resistance value of 19.2 Ω. When
energized, the 2 inner elements draw approximately
12.5 amps at 240 VAC. The 2 inner elements have a
combined resistance value of 19.2 Ω.
To access the heater assembly, it is necessary
to remove the drum. (See
