Question about Heating & Cooling
I have a Rheem Classic X air conditioner and when I turn the AC on, the unit hums inside the house for approx one min and then blows the breaker. The fan outside the house will run fine until the breaker is blown. Any comments would be appreciated. Do you think I have a contactor problem?
Does the indoor fan come on if fan comes on then the problem is out side if the fan is not coming on and the breaker blows this will turn off the out door unit also due to the 24v transformer is located in the indoor unit your system has two breakers one for out door and one for indoor units as far as your contactor goes with power off look at the contacts if pitted bad replace it most need replaced after 5yrs also check for voltage drop on the load side look at the capacitor to make sure it is not swelled up on top if so then bad unplug the fan motor and bump the contactor with an insulated object to make sure the compressor is running if not with power off remove the cap on the side of the compressor and look to see if wires are connected good they some times get lose and ends burn off also on the contactor they some times buzz when bad hope this helps with your problem
