    Check to be sure that the fan relay is getting control voltage.

    Dr. Z having a problem powering up a air handler on a a/c only system that is powered by a conventional condensor not a heat pump ? I get power at the red link board but no fan? Tried several things out of ideas? What do you suggest?

  • DrZarkloff:

    Yes, my camera took yet another oil bath. I’m really hard on my camera. I’m lucky that it’s been so forgiving. Pro-Flush works great on preparing line sets for R-22 to R-410 conversions.

    Did you get Pro Flush on you video camera? Can you use this to remove mineral oil from a line set that you are converting from R-22 to R-410a?

    I was able to clean the coil to my satisfaction. As far as if I was able to remove all of the flush, I’m sure that the vacuum pump was able to evaporate any thing that remained. The evaporative temperature of Pro-Flush is 75 degrees F.
