Heater Output

Interesting observation with the heater output in my 373. While camping this weekend noticed the last outlet in the bedroom seemed like it was blowing cold air. IR thermometer confirmed showing 55 degrees at the outlet. Next outlet closer showed 85 degrees and as you got closer to the furnace as expected the temps went up. Now the outside air was in the 30's inside was in the upper 60's, I can see some drop but does it seem normal that it would drop all the way to 55 degrees? The air flow was under pressure but still makes me thing I need to check for something but just what?

My guess is a tear or disconnect in the slinky duct work letting in cold air.
If the slinky came off the aluminum and was dumping cold air into the storage area under that vent, cold air from the storage compartment would be forced up through the vent.

Lou could be on to something............that or he's just ON somethhing

Look for a disconnect somewhere in the duct work. This may not be as easy as it sounds, but based on your readings it sounds like the culprit.

Good luck.

Hummm From underneath it looks all closed in with no access. Will have to try a little mirror work from above, looks like this may take a little bit.

My 2012 Georgetown the heat is in floor vents from the heater in the kitchen area and I think each vent is hooked up to each other.
I would get something to see if you have something left in the vent that may be restricting it between the last good vent to the bad flow one.

The heat duct is built into the subfloor so there may not be much you can do unless you find an obstruction close to a vent. The bedroom at the far end gets very little heat also. Covering a vent closer to the heater helps distribute it better. Though its not detailed in any literature, it does seem like some heat is diverted into the water tank compartment on my unit.
