I am going to a no ac service call. When I get to the call I find the condenser fan running and no compressor. I open the panel and find a wire burnt off the capacitor for the compressor. I notice that wires connection to the compressor is loose. Also the terminal on capacitor moves and shouldn’t. I fix up the wire connection to the compressor and fix the burnt wire. Also I replace the capacitor. Test the system and find a dirty condenser coil. Therefore I clean the dirty coil and test ac system.
