How To Replace The 12volt Fan
!!Unplug The Heater Before Servicing!!
(Remember That the Edges of the Metal Are Sharp. Use Caution)
Both side panels and rear panel need to be removed for easier access to the fan. The fan has two
wires running out of its housing. The fan wires will plug into the Power Routing Board
(Refer
to wiring diagram) . Unplug the fan power wires from the PRB. Use a pair of pliers to hold the
locknut and a #2 Phillips screwdriver to loosen the anchor screws that hold the fan into place.
Make sure that when you install the new fan that the label faces towards the front of the heater
(See photo below for fan direction) .
NOTE: YOU MAY HAVE TWO FAN TERMINAL PLUGS.
These are universal and will not matter which plug you use.
