I don't think that goes there.

Another system cycling on limit. They've had 2 other guys out already. Looks like one replaced limit switch and the other reduced gas pressure. I noticed airflow was low. coil and filters were clean. Looked through the heat exchanger and noticed something out of place. Worst part is, it didnt just come loose, it was put together this way.

Yea, that's a slight airflow restriction.

Haha.

Standard low flow bypass At least it didn't have a possum in it.

I had this in a resi unit.

customer said motor was recently replaced by another company. while I cannot remember details, seems this was a landlord/tenant thing and I think the handyman was in there.

funny thing is, they had to "make" this work. it does not just go there without more screws or something to hold it there.

motor was toast.

replaced it and cap, moved baffle and customer commented on the amount of airflow now versus after last repair.

That's a face & bypass damper! Wowzers.

Hey that's my line.

[keviekev70]

Really did cut-off the air flow

I'm guessing high limit or high head in heat and frozen in the summer. How something like that ever works at all is amaizing and then there's the system that seems perfect and gets all quirky for no reason.

I dont know when it was put together this way. But i did find out that it had icing issues this past summer, and 2 guys were out before me for the high limit issue.
