    if you are handy with a volt meter find your transformer

    you have a primary side and a secondary side at you transformer

    primary will be 240 volts most likely and secondary 24 volts a/c (transformer will most likely be in your air handler or indoor unit)

    see if you have that and we will go from there

I HAVE A CARRIER CENTRAL AIR, THE OUTSIDE FAN IS BLOWING INWARD AND WON'T SHUT OFF WHEN THE FURNACE SHUTS OFF AFTER TEMP IS REACHED


Check the t-stat to make sure that the "fan" switch is st to auto. If not the fan is in the "on" position and is always on. Otherwise, It sounds like your "Central Air" is a packaged unit(Furnace and air all one unit outside the home) and the fan relay inside the unit is stuck. This need to be replaced. It is the rectangular unit with the leads from the fan motor attached to it.

38CKC036 Air Conditioner: outside fan will not come on makes a humming noise...


If the humming is your compressor running (feel the large copper line going into the unit, it should feel cold aftter a few minutes of run time) then the fan motor or the capacitor or both need to be replaced, check for voltage to the fan motor when the unit is "humming" if it has voltage and will not start replace the fan motor and the capacitor. hope this helps.

Compressor not doing much


I am assuming that you are talking about a central ac unit. On a central air unit the outside fan must be running whenever the compressor is. If it's not the compressor will shut off from overheating withing minutes. First you need to shut off the unit for several hours and let it cool completely down. Then turn it on briefly to see if the compressor starts and see if the fan tries to start.( I am assuming the compressor starts and runs.) If the fan won't start try testing the capacitors. There are usually two one for the fan one for the compressor. Sometimes there will be one combo one. Mark the wires and remove the capacitor. Get it tested and if bad replace it. This will probably do the job. If not test for current at the fan motor. Also test to see if it turns freely. The motor may need to be replaced. This will run about $50. The capacitor should always be replaced when the motor is changed anyway.

Central Air Conditioner


Turn the power to the indoor unit off. Remove the cover where the fan is. Feel the motor of the fan. If it is very hot the bearings have likely gone out. If the fan is cool to the touch I would call a service company because you likely have an electrical problem that will require some training to solve.
