Having problems with your Air Conditioners ?
AC Control Transformer keeps failing.
Well it has blown the fuse on the transformer, then you have coil switch bad.It could be the coil on the contath in for cooling.But can check by taking the yellow wire a loose and see if the don't blow. The red wire is one side of the transformer and the com could be any color.But look at the red wire because it is the main wire that travel the voltage throuhg the unit.

I keep blowing the control transformer when I turn on the A/C. The system works fine when I turn on the heater. When I try to turn on A/c nothing turns on before control transformer blows.Jim [email protected]

I have a 98 Sunnybrook w/Dometic Furnace-A/C thermostat control. Just the other day, the furnace would keep running and it got very hot in the trailer until I could shut it off. The thermostat was set kind of low, but we needed to keep a little heat on in case we got a freeze. Do I need to replace the control unit which is electronic to correct the problem? I am assuming the thermostat went bad, but am also assuming it is a part of the control unit?! Thanks for your help. Dave
