Thanks again Hams

Really appreciate your advice here on this topic. I now know more about my
furnace than the licenced quaified repair techinician who I paid to diagnose
the problem. That is true because I took the couse HVAC engineering about 20
years ago and spent years doing heat lose heat gain caclulations for
industry. But never knew there was a simple little dimple reset button in
the stragest place. Dam.

Now I know and there is nothing on this unit I cannot repair myself.
Servicing and cleaning is easy.

Sorry I upset a few of the hams, I know it is off topic however there is no
groups on my server that are active, this one is so sorry I upset some hams
with my off topic question but I know there is a lot of knowledge in this
group,,, and I am thankful for that.

73s and happy holidays.

Hey, Thanks for the good advice.

I recently installed a sauna and spa on the same floor, it just happened
to be that particular evening that the limit switch tripped when I had
used those two units so I think I got a lot of humidity and heat in that
basement. Then I also had to remove the intake pipe supplying the fresh
air from outside because I had to move something else so that pipe was
off and it was sucking in air from that room for combustion. Also, the
heat supply ducting inspection plate had been removed from that room
because I wanted to add some heat into that room. When I feel that
intake area near the tripped limit switch, it is very warm. Now that I
have re-connected everything it is cold. So maybe those scinarios had
direct responsibility for tripping that limit switch. That is what I am
thinking. I think too much heat in that chamber caused it to trip. Doing
its job. Hasn't tripped yet after about 6 hours of operation on and off.

That was probably the problem. Shouldn't have been a severe overheat,
but maybe enough to push it slightly over the edge as far as the limit.
I doubt you will have any more problems if it's run OK so far.
