I just had a damper motor replaced for just that problem.

13 year old motor. I had been manually moving it past few months. Pretty fancy motors for those things now.

I've been amazed how nice it is to have properly functioning heating zones.

If it's a zoned system then yes, damper problem. Are the dampers... -- Spud 01/07/2022 08:20AM

I’m not sure. I’m a little busy with cardboard boxes at the moment. ** -- ElbertoHokie 01/07/2022 08:29AM

One unit for heat? one thermostat? ** -- bigbadbird 01/07/2022 08:09AM

One thermostat for each floor. -- ElbertoHokie 01/07/2022 08:13AM

Prob one set of ducts would be first guess - it goes nowhere or everywhere -- bigbadbird 01/07/2022 08:15AM
