I have a problem with hot air. My blower and a/c condensor are working (my double check that the condensor is working is that the coil in the blower cabinate is cold). The problem is that there is still hot air coming out of the vents. Why is the blower not sucking the cold air out. My guess is that the heat pump may (for some odd reason be on). does anyone have any ideas?

Your problem is not with hot air. That is an effect, not a cause. The a/c condenser is the heat pump so it can only run in heat or cool mode. Since you say coil is cold I would venture to guess it's running in cool mode. Your electric backup heaters are running with a/c. Possibly due to a bad defrost control or a short in your control wires.

When I troubleshoot, the defrost control is in the condensor unit correct? Is there a way to test it with my volt meter? Also, if the electric heater is the issue is there a way to disconnect the power from it? The wire short is a possibility because I put in a new transformer, contactor, and timedelay. Would any of these units turn the electric heaters on?
