AC Out Side Unit Doesn’t Work in Los Gatos, CA
The reason for the unit’s failure is a dried run capacitor. Insufficient capacity to start the compressor motor caused a large starting current of 123 Amps, which led to the melting of the contactor. In addition, the installed 60 amp fuses exceed the required factory value, which is indicated 50 amp. The run capacitor, contactor and fuses must be replaced.
