FRAME HEATER REPLACEMENT
Always turn off power to the case before working
on any electrical components. The old wireway
covers must be removed to access the door frame
heaters. Begin by inserting a putty knife into the
groove between the wireway cover and fiberglass
frame, about an inch (25 mm) away from joints in
the frame as shown in Figure 17(A). Carefully
begin to pry off the cover.
As shown in Figure 17(B), use a second putty
knife or flat head screwdriver to hold up the cover.
Pry the remainder of the section up, using putty
knife only, until the entire cover is off and the
frame heater inside the door frame is exposed.
Door frame heaters shown in Figure 18 may now
be replaced.

Hussmann recommends against frame heater
cycling with
Innovator doors to prevent door
seals from freezing to the frames and tearing.
Always disconnect the electrical power at the
main disconnect when servicing or replacing
any electrical component. This includes, but is
not limited to, such items as doors, lights,
fans, heaters, and thermostats.
