2003 Bryant R-22 AC system was operating in cooling mode upon arrival. Indoor blower is operating and thermostat is operating. Inspection of outdoor unit showed that compressor is running but condenser fan motor is not. Compressor was making louder than usual noise while running. Entire system was very hot to the touch. Service disconnect was very hot aswell. Pulled disconnect and used garden hose to cool system down to safe temperatures. Once cooled down, inspection of electrical components showed that 55/5UF capacitor is reading 12/0uf. This explains why the compressor was running, and creating excess heat, and why the condenser fan motor was not operating. Replaced with new 55/5uf capacitor setup and test run operation. Compressor and fan motor come on as they should. Compressor is no longer making unusual noises. Refrigerant lines carry a normal temperature. Did not check refrigerant pressures as there are no issues suspected. System is operating in cooling at this time. Due to age
