Furnace has taken to "chirping" -- sound of two pieces of
metal rubbing against each other. Traced to one (?) of the
removable door panels (*probably* rubbing on the OTHER
As this panel covers the combustion area, flame is nearby.
Heat is to be expected!
My initial thought (when I thought it was the *blower*
area door) was to put some self-adhesive "felt" on one
of the offending surfaces (the "fuzzy" half of some velcro).
But, not too eager to try that with the presence of flame.
Any other suggestions?
I'll pull the blower out this weekend and check to see if it's
got a balance problem (bad bushing/bearing?) leading to any
possible increase in vibration (nothing obvious).
Most blower doors don't take much heat. The
fuzzy felt or some kidn of rubber should be
okay for a while. Until the glue dries and
the fuzzy falls off. But that won't be for a
Checking the blower is a good idea. They do
get dirty and tend to vibrate.

With that on the edge of the metal door/cover, I wouldn't be
worried about fire. When the door is in place, no flame should
be anywhere near it and it's sandwiched between the metal of
the door and cabinet, not exposed, when it's installed.
Like you say, the fire should be no where near
the door edge. I'd be happy to sticky felt, or
several layers of electic tape.
One time (80 percenter Miller furnace in my old
trailer) the furnace started to squeal badly in
the middle of the night. Blower motor bearings
dried out. I was able to get the blower out, and
put some oil in. That was memorable. Hint: Mark
the blower housing location with marker before
removing the bolts. So much easier to put back

In the middle of winter, the last thing you want to do is break something that didn't need fixing M

I'd just throw a hard drive magnet at it - or 2. One on each side of
the door, bridging the gap to the furnace body. But then again, I
have about 125 of them stuck to my furnace duct (just a good place to
