[TR] TR 250 Heater problem

[DAVID MASSEY]

 If it were mice you would have known long before now.  I had mice make a nest in my heater.  Gaaag!

 I think, it must be the seals.  I am going to try to get a look at it with my inspection camera, but I don't think I will be able to get it inside the box.  
  I am afraid the only thing to correct it, is taking out the heater box and rebuilding it.
  I don't think it could be a mouse nest, from what I can see.

   Two things come to mind.  
  
  1) Air is bypassing the core on that side.  It has been years since I took one apart.  Is there a foam piece sealing off the gap between the core and the sheetmetal housing that has perished? 
  2) The core is partially clogged.  Certainly there is some flow but some tubes may be clogged leaving a portion of the core cool and, hence, the air is not heated.  (Actually, I have a little difficulty with this one since the tubes run right-to-left and if there were clogged tubes the problem would be symmetrical.  But still worth looking into it.)
