Have HVAC Questions? Ask an HVAC Expert for Answers
I'm going to open this up to my colleagues so one of them can help. Please don't respond (even to acknowledge this post)until you get a response from us. If you respond first it will only delay your answer.
Hello , there are electronics controls in the zone control panel causing this, or just a defective or stuck damper motor on the zone that is not working well.
Tell me a lot about your technical background and if you have a multi meter or not, so that I can coach you most effectively.
We can go from there.
