    Midea 36000 too hot condenser and overload after few hours problem.



    hi. Dear friends.
    I have Strange problem with midea air condiditioner that condenser become too hot and compressor draw high ampere about 20 21 with 60 psi with r22 gases.
    Current witch printed in nameplate is about 17 and rated current is 25 A.
    If we increase gas the drawn ampere increase and Cause compressor overload.
    In 60 psi after few hour compressor overloaded Basr on weather condition.
    I changed cpacitors( it has 2 Capacitor with 60 mf) and used presure nh3 to clean air conditioner evaporator and condenser but nothing changed.
    please help me to know what is problem.
    It has capilary tube.

    if pressure increase abnormally this could be the 4 way valve is faulty
    or that could be result of condensor fan faulty
    the unit was new?

    Just giving compressor amp draw and suction pressure does not give us a clear picture of what is happening on you system.

    Can you take more measurements around the system and post them on here?

    Discharge pressure
    air temp on to the condenser
    air temp off the condenser
    liquid line temperature
    liquid line pressure
    suction line pressure
    suction line temperature
    evaporator air on temperature
    evaporator air off temperature
    ambient temperature

    60psi with R22 is a good suction pressure.
