Affected Component: EQUIPMENT:APPLIANCE:AIR CONDITIONER

Summary
This bulletin provides a diagnostic procedure for a chattering-type sound originating from the a/c compressor assembly. In the case where a refrigerant leak is identified as coming from the a/c condenser, the level of refrigerant oil may also drop and cause the internal vanes of the compressor to make a chattering-type sound. A new-style A/C condenser has been established with enhanced corrosion resistance.
