Heat Exchanger
The freezer heat exchanger passes through the ceiling
of the compartment.
NOTES:
•
The high-side filter-drier must also be replaced when
replacing a heat exchanger.
To remove a heat exchanger, first capture the refriger-
ant from the sealed system, then (See Figure 6-124):
1.
Extract evaporator mounting screws, then pull and
rotate evaporator so heat exchanger is accessible.
2.
With a file, score a line around capillary tube, 1” or
less from evaporator inlet, then fatigue capillary
tube at this line until it separates.
3.
With a tube-cutter, cut suction tube 1” or less from
evaporator outlet stub, then remove evaporator
from compartment.
4.
With a tin snips, or similar tool, cut heat exchanger
in compartment as close as possible to ceiling
where heat exchanger passes through.
5.
Use a tube-cutter to cut drier from condenser outlet
tube.
6.
Using a tube cutter, cut suction line approximately
1” from compressor.
7.
Pull remaining heat exchanger from unit.
NOTES:
•
Do not sweat tubing apart. Doing so will induce
moisture into the sealed system.
•
When replacing the heat exchanger, it is recommend-
ed to attach it at the evaporator end first, then feed
the heat exchanger through hole, up to compressor
area.
