Inside of the unit you will find (see attatchment) a feeler bulb witch will be faulty. You might only find 1 feeler bulb witch will be highly rare most of them has two, one for heating and one for cooling. Now what happens is on the evaporater where it will be located is if on heating the fan does not start until the bulb picks up that the evaporator is warm enough same goes for cooling, only defrence is that it starts the fan when the evaporator is cold enough.
