Re: Induced Draft Blower tube issue
Ah yes --- the infamous tube issue.
I had an issue with the tube/ hose on my own furnace last year. In that case the hose had developed a crack right at the point where it slips onto the metal tube fitting at the blower. Unfortunately cutting the hose at that point rendered the hose to be too short ---- replacing was the only option.......... btw ..... it was the black as well. Though they may also be an orange/red color or clear.
They will eventually deteriorate or become brittle and need to be replaced but in the short time yours had been replaced doesn't sound normal.
Just a guess -------- it seems the hose is losing it's " memory " not allowing it to expand and contract properly any longer. Perhaps it may be the environment ---- the crawl space ---- may be there is a high enough humidity that's causing the hose to prematurely deteriorate.
Perhaps you can fashion a hose clamp out of some sturdy wire wrapped and tightly twisted around the hose--------- unless you can find a barrel or band clamp small enough to use --------- at the fittings and see if it helps with maintaining a tight seal .
Or ------ you might try the clear hose .
When I needed to replace mine the HVAC supply center recommended the clear hose ---- apparently is has a better silicone compound than the black and orange/red --------- though I can't confirm this. However , since replacing mine with the clear it's work fine ----- time will tell.
Too bad you weren't close by I could give you some ----- bought 3 feet of the hose.
Hopefully this helps.
