Short Cycling blues & low pressure control switch
Hello All,
I'm dealing with a condenser (404a),where the compresser short cycles before beginning a cycle, and after the compresser stops. I'm not sure, if the liquid line solenoid is leaking; if the pressure control has a leak in the diaphragm; or if the pressure line from the compressor is actually increasing in pressure and causing the pressure control contacts to close. I have been experimenting with different pressure control settings but have not found a solution. Help, anybody that can tell me how to test pressure contols switches, solenoids, pressure leaks through compressor valves, etc.
