Ford Escort Questions - ac compressor not kicking on - CarGurus
An AC system has many components: compressor, condenser, receiver dryer, evaporator, and hoses. The AC compressor has several moving parts including pistons and valves. These internal parts can fail, causing the AC compressor to stop working. It is common for the internal parts of the compressor to come apart and disperse metallic debris throughout the system. Consequently, it is a requirement to replace the orifice tube and the receiver dryer when replacing the compressor since some of the debris may have ended up there. For an AC compressor to work, it needs a clutch, bearing, and an electrical connector. The clutch can burn or the bearing can fail.
