Furnace issue

when i run my furnace very little air comes out of the ducts. when i remove the cover to the furnace it seems to be blowing plenty of air. when i reach down into the ductwork below the furnace it seems to be crushed up a bit. when i look under the trailer there is a bunch of expanded foam in this area i am wondering if this is factory or was someone trying to fix something and made it worse.. the duct work seems a bit narrow to begin with so if its crushed up a bit it could be my problem. does anybody have a drawing of what the ductwork looks like the demensions and where it runs. Thanks,

mark

Don't think you'll ever see a drawing, just FR's way! You might take a lightweight tissue or cloth under the trailer or in compartment where the heater is and see if you can determine is it a leak or restriction. My money would be on both.....

We were not getting any heat in our living room and I discovered the heater hose to that area had been stretched too far when the factory connected it to the furnace causing a sizable tear. The dealer is fixing it under warranty.

greymedic, my hose melted. I replaced the first 4 feet of the feeds with metal aluminium duct that can handle the temperature better.
