Condenser Fan stops running- Fan or capacitor? When the motor craps out it doesn't make a noise or come to a grinding halt it just stops. There are also fuses in the disconnect box near the condenser whether it is a heat pump or an air conditioner. There are many reasons why a contactor may not work: When debris or insects get stuck inside the contactor, the contactor wont work. Eventually, the layer of black soot prevents the metal plates from forming contact with each other. might the Motor run, but then over-heat after a few minutes ? A faulty cooling fan relay can also negatively affect air conditioning (A/C) performance.The reason being, on most vehicles, is that the cooling fan doubles as a condenser fan.When the A/C is turned on, the fan moves air across the A/C condenser, thereby removing heat from the refrigerant, which changes from a vapor to a liquid state as it gives off heat it . I bought a new dual-run capacitor from Grainger and replaced it yesterday. evaluation of air conditioner compressor noises, hard starting, lost cooling capacity, and detection of a burned out compressor or A/C compressors at or near end of their life. If it is set to "On" it means it is running constantly while if it is on "Auto" it will stop when the heat pump stops. Finally a senior tech came out and recognized that the fan required a different capacitor than what was initially changed in. Is it damaged? The fan capacitor may also be labeled.
