Paul,

yes I think the led indicates the thermocouple is changing resistance
according to change in temp. How long do you hold down the "override"
button? I keep mine depressed for a good 20 -45 seconds, just to be
sure.

that an indication that the thermocouple is, in fact, working and

aligned, or is it more complicated than that?

If you have a voltmeter, you could check the millivolts the thermocouple
produces.  When they get old they produce less.  People who service
furnaces

replace them a lot.
I'm not sure what the specs are, perhaps that can be looked up.
