With the combination of good temperature and humidity control, it is possible for
contents in the CZT drawer to last much longer than in a standard crisper drawer.
Servicer’s Note
Currently, the CZT drawer will be replaced as a module with the old unit returned for
analysis. In the future individual components will be available for repair.
Cabinet Lighting
The fresh food and freezer door switches are low voltage switches. The opening and
closing of the doors are sensed by the switches and in turn by the Main Control board.
The Main Control board actually turns on the relay for the compartment lights.
There are at least three freezer lamps with the possibility for four lamps for a dispenser
model. The fresh food section has a total of six lamps. Two of the fresh food lamps are on
the CZT assemblies.
If the door is open long enough for the door alarm to activate (10 minutes) the lamps will
be turned off. This will help minimize the temperature impact on the contents of the
compartment should a door be left open.
Servicer’s Note
With this many lamps inside of the cabinet, if the relay contacts were to weld together,
the compressor would be hard pressed to maintain the desired temperature. If the lamps
do not turn off when the door switches are held in the door closed position, enter the
Service Test Mode. All lamps should be off in the Service Test Mode unless you are
specifically using the Test Mode to turn the lamps on.
The lamp circuits can be energized from the Service Test Mode. Service Test 13 will
energize the fresh food lights while Service Test 14 will energize the freezer lamps.
