DISCONNECT POWER SUPPLY TO CABINET!
Center mullion heaters not foamed in place on later
models. The heater can be accessed from inside the
cabinet.
Remove lamp (if applicable).
Spread inner plastic extrusion apart. Working down
one side and then the other. Slide a putty knife about
3/4" between mullion back panel & the plastic
extrusion. Carefully pry back panel from the mullion.
This will expose the foam insulation. The mullion
extrusion will have to be opened up also in order to get
foam insulation out. The heater is taped in place. The
heater lead wires exit the mullion and are plugged into
a terminal board located just above the door opening
in a raceway. Install the new heater in the same
manner and reassemble in reverse order (see photos).
