    If you run it in this condition you will ruin the compressor. See if the inside blower wheel turns freely; if not then replace motor. Four things can be bad: the fan motor inside, the fan relay, the capacitor on motor, and the t-stat. Most likely you did not oil the motor and it failed. If locked up replace it and oil before installing it as they always need a few drops of special oil first. Replace capacitor with motor and make sure rotation is in direction fan blades are pointing: If you are looking at fan and blades are pointing to right then motor must turn them clockwise and vice versa. The fan relay has a coil and contacts. You test the coil with an ohm meter which should read a few k-ohms. The whole assembly slides out and can be tested in a few minutes at any parts house.
