WARNING

Avoid inhaling fumes and burns from any acid formed by burnout of oil and

refrigerant.

If the oil is clean and clear, and does not have a burnt acid smell, the compressor did not fail because of motor burn

out. If a burn out is not indicated, refer to direct support troubleshooting WP 0047 00 for other malfunction causes.

If the oil is black, contains sludge, and has a burnt acid odor, the compressor failed because of motor burn out.

Proceed to replace the compressor.

REPAIR

Wiring

Remove the insulation to expose 1/2 inch (1.27 cm) of bare wire on each side of break or damaged insulation.

Insert the ends into a splice-connector, splice and crimp the connector to make firm electrical contact.

Alternatively, heat-shrink tubing may be slipped over one end of the wire before splicing, then heated after the

splice is made and soldered so as to cover the spliced area.

Be sure that no bare wire is exposed after the splice is complete.

Replace broken terminal lugs with exact duplicates.

Check continuity terminal-to-terminal.

INSTALLATION

Install four rubber spacers (7) onto the four compressor mounting bolts (11).

Install four spacers (6) onto the four mounting bolts (11).

Install four resilient mounts (5).

Install four grommets (4) onto compressor mounting hole.

Carefully position new compressor having a full and proper charge of synthetic oil on compressor mounting plate

bolts (11).

Secure compressor with four flat washers (3) and nuts (2).

Connect the compressor heater (12) if required.

Connect electrical wiring at the compressor electrical receptacle. Refer to wire list and schematic diagram (WP

Replace filter-drier. See WP 0051 00.

10. Connect piping. Provide a flow of dry nitrogen through the system to protect inside surfaces of refrigerant piping

from scaling while brazing (WP 0046 00).

11. Install condenser fan motor. See WP 0037 00.

12. Preliminary leak test unit. See WP 0047 00.
