    Dear Dr.Zarkloff,
    I am Lito from the Philippines, just want to ask why my aircon’s high fan shuts down but my compressor is running.I followed the wiring diagram but it still shutd down. Thanks and I learn a lot from you.

  3. DrZarkloff says:

    Unless you have a variable speed condensing fan motor then it sounds like you could have a bad run capacitor and/or motor.

    if it doesn’t go to zero you need to spend 10 bucks to replace a bad gauge. You don’t need different gauges for different refrigerants, you need different gauges (hoses really) for different oils. Good luck pulling 30″ mercury, on earth at least, good luck pulling 29.9. Maybe the problem is your using the bad gauge instead of a micrometer.

    oh yeah and the liquid filled gauge does have a adjustment, it’s on the back of the gauge.

    thank you DrZarkloff for the video,
    although I am not an ac tech but I have learned a lot about ac from your videos,
    question regarding the valve manifold, when both valves are fully open are both sides” the high and the low are open to ach others” thats how I understood it”
    the other question is why do we have two fittings in each sideو
    and sorry for the poor English as it is not my 1st language

    thanks again

  22. DrZarkloff says:

    One side is the low side and the other is the hight side.

    Dear Dr. Zarkloff,
    I would ask if it is possible to replace a 2horsepower window type unit to a 2.5 horsepower in the same unit? My aim is to increase the cooling capacity of the unit.
    Thank you and more power!
    Lito Pabalan

    It would probably work okay in the summer, but then it could become a problem in cooler weather.
