What can be better than standing indoors and hiding under the AC unit till the heat wave is melting everything outside. Unluckily, if your air conditioner is out of order, the scenario above will be impossible. Here is a solution for the Carrier A/C in case when the condenser fan isn’t working. Check if the blower is coming on, under the normal condition it mustn't blow room temp air. When your house has no cooling, inspect the condenser unit outside. aMost likely the fan is not turning, and the coolant lines into the house are not cold at all as they should be. When the thermostat inside the house tells the unit to come on, there should be a click and then a bunch of humming. That is a sign the thermostat isn't defective. Power the unit off, and take the grill and fan off the top - fan appears to spin freely although that could still be the problem. Put the fan and grill back on, and open the electrical panel on the outside of the unit. With the power on, the voltage heading into the contactor reads 240V so there is good power to the contactor. The humming sound may be coming from inside the condenser area and not from the contactor itself, it is hard to tell. Even if voltage across the control lines reads 27V that is probably not the deal. It is a good idea to get professional assistance with your HVAC system. Surely, remember to clean your air conditioner from time to time. This simple step prolongs the life of your unit and saves the owner potential hundreds of dollars.
