have a lennox HP 19-411 heat pump. After not needing AC for a couple of
weeks I turned the thermastate to cool but after a couple of hours noticed
the house was not cooling. Went outside to compressor and the fan was
not turning. Turned off breaker to outside unit. Took grill off the unit
to turn the fan by hand. Initially the fan was stuck but after a little
force the fan blades spun freely. I touched the fan motor with hand and
it was warm. Turned breaker back on with thermastate still on cool but
the outside compressor would not come on. Fan blades spin freely by hand.
Turned thermostate to heat, raised therno temp, went out side and
compressor no running. I m thinking problem with fan motor frying. How
would i check? Or any other suggestions.
Its old, its worn out, its paid its dues, and its ready to collect social
