c. Connector replacement. (Refrigerant system discharge is not required.)
(1) Assuming that the power has been disconnected at the power source, and covers have been
removed during access and testing, proceed as follows.
(2) Remove the retaining hardware from the connector. Pull the connector out of the box to gain
access to the solder connections.
(4)
Using tags and wiring schematic (fig. 5-17), solder wires to new connector. Remove the tags.
(5) Secure the connector to the compressor junction box with appropriate retaining hardware removed
in step (2) above.
*d. Heater thermostat replacement. (Refrigerant system discharge is not required.)
(1) Check to see that the power has been disconnected at the power source and covers have been
removed during access and testing.
(2) Tag and disconnect two thermostat leads.
(3) Using pliers, bend retaining tabs back.
Remove thermostat.
(4)
(5)
Install new thermostat as follows:
(a) Insert thermostat and carefully bend retaining tabs back to secure thermostat.
(b) See tags on removed thermostat, Correct thermostat leads.
(c) If this completes the repair, install junction box cover.
e. Compressor replacement
NOTE
If compressor replacement is necessary, there are two approved compressors
available. Keco compressor (94833) 120K0290-11 or Carrier compressor (97403)
13226E12171. These compressors are interchangeable, however they will require
numerous refrigerant tubing changes. Should changeout become necessary, see U.S.
Army Mobility Equipment Research and Development Drawing (97403) 13225E8000
for refrigerant tubing change information. These refrigerant tubing changes may be
avoided by ordering a replacement compressor of the same manufacturer as the
original.
(1) Check to see that the power has been disconnected at the power source, connectors (P4 and J4)
were disconnected and that covers have been removed during access and test, proceed as follows.
NOTE
The compressor is mounted to the cabinet base by four bolts that are inserted from the
underside of the base. In order to remove the compressor, it is necessary that the
entire air conditioner be raised and placed on blocks of sufficient height to allow for
removal of these bolts from below the base.
*Effective for Carrier Compressor.
