Component
Drier Drier is placed at post
condenser loop outlet and
passes liquefied refrigerant to
the capillary.
Desiccant 12grams XH9.
Long tail drier P/no 814843P.
Water valve Controls water flow to the
icemaker.
Controlled by thermostat in
icemaker.
See Ice Maker Section for
further information.
Electric damper Damper control balances the
control air delivery between provision
and freezer compartments
providing temperature control
for the fresh food
compartment.
The Electrical voltage
activates damper control and
the door closes, restricting
flow of air from freezer
compartment to fresh food
compartment.
Description

Test Procedures
Drier must be changed every time the system is opened for
testing or compressor replacement.
1. Cut drier out of system using the following
procedure. Do not unbraze drier.
2. Applying heat to remove drier will drive moisture into the
system.
3. Score capillary tube close to drier and break.
4. Reform inlet tube to drier allowing enough space for large
tube cutter.
5. Cut circumference of drier 32mm below condenser inlet tube
joint to drier.
6. Remove drier.
7. Apply heat trap paste on post condenser tubes to protect
grommets from high heat.
8. Unbraze remaining part of drier. Remove drier from system.
Discard drier in safe place. Do not leave drier
To avoid death or severe personal injury, cut drier at correct
location. Cutting drier at incorrect location will allow
desiccant beads to scatter. If spilled, completely clear area
of beads.
Check resistance across coil windings.
Check resistance across terminals.
If no resistance across terminals replace damper control.
