BRYANT fb4anf030 not blowing hot air

Heat pump furnace system blows but no hot air. Any ideas? Can one even still get parts for these older Bryant units? Thanks

The most common failure is the dual capacitor in the outdoor unit.

Does the outdoor compressor sound like it is running?

Is the outdoor unit running?
Is the auxiliary heat working?

Same issue

I have the same issue checked the unit in my attic everything looked normal. Large cooper pipe feels warm small cooper pipe feels normal. Blower was blowing felt a hint of warm air coming through the radiator before the blower. I checked the outside unit notice ice forming on the small cooper pipes inside the unit on the radiator and around the outside of the unit. I removed the panel on the side of the outside unit everything looked normal. Aux heat does work. Any ideas? Currently outside temp is 43 degrees, inside 66 degrees, thermostat set to 70 degrees.
