Drain Tube Heater Removal
(ICB700BCI, ICB700BFI Only)
The electrical connections for the drain tube heater are
located at the back of the compressor area with the
braided heater leads entering the sump drain tube from
the compressor area.
To remove the drain tube heater, the kickplate/grill will
need to be removed first. Then, extract the two screws
that secure the unit tray to the unit and slide the tray
out (See Figure 7-41).
NOTE: It may be necessary to disconnect the com-
pressor electrical leads in order to pull the tray out far
enough to access the drain tube heater.
Unplug the drain tube heater electrical leads and pull
the heater from the drain tube (See Figure 7-42).
NOTE: When installing the replacement drain tube
heater, push the braided heater leads into the sump
drain tube until splices are 64 mm (2-1/2”) from drain
tube outlet (See Figure 7-42). Also, it is recommended
to remove the sump cover to make sure the drain tube
heater has slid under the evaporator.
