Compressor removal

TM5-4120-347-14

(4) Place the new heater in the mounting tube clip on the lower side of the compressor.

[5) Run wires through the grommet in the compressor junction box.

(6) wiring diagram figure 4-5 and tags on the removed heater. Connect heater leads to J10 pins F and

d. 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 wider connections.

(3) Tag and unsolder wires.

(4) Using tags and wiring diagram figure 4-5 solder wires to new connector, Remove the tags.

(5) Secure the connector to the compressor junction box with screws and lock washers.

e. Compressor removal. (See figure 5-18.) Two people are required for compressor removal.

(1) Assuming that the power has been disconnected at the power source and that covers have been

removal during access and test proceed as follows:

Discharge and purge the refrigerant system per paragraphs 5-9 and 5-10.

Debraze the tube connections to the compressor.

Lift or tilt unit to gain access to the under side of the unit.

Loosen the access cover screws and swing the four access covers out of the way.

Remove the four sets of compressor attaching hardware.

If compressor is being removed due to burnout, use care when lifting to avoid touching compressor

sludge. Acid in sludge can cause burns.

(7) Carefully lift the compressor from the unit.

(8) Check the compressor to see if a motor burnout is indicated.

f. Compressor motor burnout.

(1) After removal of a bad compressor from the refrigeration system, remove all external tubing and tip

the compressor toward the discharge port to drain a small quantity of oil into a clear glass container.

(2) If the oil is clean and clear, and does not have a burnt acid smell, the compressor did not fail because

of motor burnout. If a burnout is not indicated proceed to g.

(3) If the oil is black, contains sludge and has a burnt acid odor, the compressor failed because of motor

burnout.
