This is a three ton heatpump must likely it is a 35/5uf capacitor. But if you can read compressor tag it will tell you size it requires and also fan label will do some for it.you will need to ask for a dual capacitor from supply house make sure you pay close attention to hoe wires hook up so you can wire in new on before removing wires make sure you have high voltage turned off to unit.take pic with phone this will help when you rewire

It really depends on the climate and the design. In Michigan where the winters are cold and the humidity high the air cooled heat pumps run constantly, but here in Arizona they cycle on and off like a regular air conditioner. That's the best answer I can give. Hope this helps and good luck.

Jump out limit switch blower should stop and inducer should come on then the heating sequences should start from there

Which coil?, indoor or out? Indoor coils freeze due to clogged filters, low freon, blower motor not working. Outdoor coil freezing could mean, in rare cases in cooling mode, reversing valve not shifting.

Joe, If the system is only 1 year old I would guess it may still be under warranty. Check with the installing dealer. Might not cost a thing to fix it.

Check the control board.

If the emergency heat doesn't come on very often, it will burn off debris that has collected on the heat exchanger causing the smell. Also, check that there aren't any chemicals that are being stored around the unit that would put out fumes that can be drawn into the system and when heated, cause the odor.
