THERMOPROTECTOR SERVICE PROCEDURE
This bulletin has been updated by TSB #105990, 7/6/90 (added to the end of this TSB). This bulletin is to be used as additional information for Section
4-7 of the 1985 to 1990 L Series and Loyale Genuine Subaru Service Manuals.
PANASONIC A/C TROUBLESHOOTING
Use the following manufacturer recommendations for diagnosing and servicing the thermoprotector.
THERMOPROTECTOR SERVICE PRECAUTION:
Never attempt to service the compressor thermoprotector without first completely discharging the A/C system. High side pressure is in contact with the
thermoprotector internal surfaces. Removal without discharging the A/C system may cause an extreme safety hazard.
THERMOPROTECTOR DIAGNOSIS AND SERVICE PROCEDURE:
DIAGNOSIS
Check that continuity across thermoprotector circuit is open when temperature is greater than 330~ F, R = infinite Ohms.
REPLACEMENT PROCEDURES
1.
Discharge A/C system.
Important Note:
Various R-12 reclamation procedures are currently being studied by the federal and state governments and acceptance of those procedures may
result in a prohibition against the release of R-12 into the atmosphere. Venting R-12 into the atmosphere depletes the earth's ozone layer. For that
reason, we strongly recommend use of a refrigerant reclamation station. If federal or state regulations are adopted prohibiting the discharge of R-12
into the atmosphere, a refrigerant reclamation station must be used.
2.
Remove snap-ring and thermoprotector.
3.
Clean sealing surfaces.
4.
Lubricate new O-ring, replace thermoprotector and snap-ring.
5.
Evacuate and recharge A/C system, refer to charging instructions.
6.
Leak check during operation.
