Ok, now that my furnace was scrubbed and cleaned and a new thermo
coupler for the pilot ignition was installed, I got a new filter to
install. However, as I pushed the filter into the slot, I accidentally
brushed/hit one of the wires on the blower and the flames died out and
only the pilot light remained. I replaced the blower lid and the
burner door, went upstaris to make coffee, and went downstairs to hear
that the furnace was burning full blast . I opened the burner door
to look inside, and the flames were burning birghtly, then they died
out and only the pilot light was on.

I don't remember this ever happening before. The flames were always
burning brightly and never went to pilot status when I had opened the
door previously. Now that the burners are cleaned and scrubbed, and
all the scale and rust has been vacuumed out of the furnace, is the
above normal operating procedure?

Thanks

Yes, that most likely is normal operation. There is usually a door switch
that turns the unit off and on. Obviously I can't see it from here, but you
can...look for some type of push switch that the door come in contact with
around the edges of the cabinet.

More like a vertical lid that slides off with great difficulty. With
the burner door on and the blower door/lid in, the cycle is 1) pilot
light 2) full burn 3)blower on 4) blower off with full burn 5) pilot
light. Basing this on sound since everything is closed. I didn't
notice any switch where the blower door lid would come int contact
with. I wonder if the brand new thermal coupler is responsible for
this cycle.
