I have changed the wires three times but am not sure it was a good test.
I need to stop for some air to breath.
Will try again after lunch and advise you of the results.
I haven't done my retest yet.
On my origional test that you suggested I wasn't sure of the results because the door was off the bottom of the furnace and the safety lever was not depressed.
On the test that I tried, reversing the red and white wires, The fan would not even operate. After replaceing them to the origional possition the fan still would not work which it had been before the trade. Hope I didn't damage anything..
Tried the wires connected both ways.
Tried the 80 degree setting with and without the fan.
The fan is working and the light on the thermostat is working.
We waited several minutes in each condition hoping that more time might cause some change.
Using natural gas which we also use for our dryer and range.
I just found more information from you.
I will try the twisting for direct contact.
I don't know where the fuse is located from your description.
I don't see any circit board. Is it on the furnace or the outside unit?
The pilot is electronic. The furnace is gas.
Information on my Honeywell Thermostat:

I don't know where there is a circuit board.
Carrier Air Conditioner

Have you located the circuit board?
Did you receive the information I sent about the Thermostat and the Model, Serial No., etc. for our Carrier Furnace? Two seperate replies.
It is everything I can locate at this time.
Remember that it is a gas furnace.
I have not located either of these.
Are these on a gas furnace?
I don't recognize a door.
I just work with upper and lower panels on the side with the vent.
Can you direct me to the area with a door?
Did you receive the Model information that I sent?
That is the same place that I have been working.
We replaced the run capacitor in this area last year.
There are gas valves in the top portion and several burners.
The bottom has a lot of wiring but no fuses that I can spot.
I'm an old man that has trouble seeing and doing things.
There is a cluster of wires coming from from the pilot and disappearing into the bowels of the furnace. At one point there are two wires that go to the only thing that looks like a circuit board. there are only two terminals and no fuses on this board or anywhere in the lines that I can detect.
Thank you for you efforts.
I was hoping that the Model, Serial Number, etc. might be the difference.
I don't think the problem is dangerous. It is a repetitive condition that occurs on the first restart every year.
