I have a Tappan Heat Pump unit and the fan does not blow air in the house. What could be causing this problem. The unit is working fine it just will not blow inside through the vents.

Check the blower in furnace/airhandler,go to where the airhandler/furnace is,you should hear very clearly if the blower motor is running,while you are there check the filter,also the copper lines coming in from outside unit are they clear and not iced up?
Set the tstat to fan,, not auto,, does the fan run now?

Unit does not have furnace inside all of it is inside the unit outside.

OK, didn`t know that,,
Still yet you or someone need to check it out to see if the blower is working,a package unit has to fans,one that cools the ac/heat pump part and another that blows into your ductwork into your house

I had someone to check the unit and he says that the mother board has gone out on the unit and it needs to be replaced.

Good luck
