I’ll check to see what wires are plugged where but do you men the exhaust motor or the main blower motor?
The A/C company thinks all of the ducts and distribution boxes need to be bigger. They want to replace all of them - which is going to be too expensive to just fix the heat that gets used a few nights a year down here.
I’ve done some more experimenting. There is one of those black light things I stopped using years ago in the supply plenum (I am not sure on terminology but it is the top of the air handler where the air is being supplied to the house). I took that out which left a 3-4 inch hole for the air to blow out. It didn’t help. Even with air coming out of there it shut down. I also cut a 5-6 inch square out of the return plenum in that little closet. (See pic - I taped it back up) I figured that would get more air into it but it had no affect - it still shut off after a few minutes.
So - if I add a larger return duct - is that effective enough or do all the other ones need to be replaced. I guess what I mean is, can you compensate for inadequate sized ducts by adding more, or is the real fix replacing. I’d like ro add a vent to a room that always os difficult to cool in the summer anyway, so I could add a supply vent and and return vent, but I’d hate to do it if it isn’t going to matter.
Thanks!
