I have not tried that If you want me to try that it will be a few hours
because it is running now so I will have to wait until it stops at 72 degees
and the find somebody to turn the thermostat up while I watch in the basement.
OK STAND BY
Your test won't work because the themostat has already called for heat
(and failed) before I crank up the temp to look for a start.My thermostat is set at 72. The temp was down to 70 when we tried your test by turning it
up to 75. t did not start until I turned the power off then on again. I think
what I would have to do is set the stat down to a low number where the
room temp is much higher and then try your test. If that is correct let me know and I will do it that way. STANDING BY
With the room temp over 73 we turned the stat down to 55 to make sure it was off. With me watching the furnace and my assistant turning the temp
of the thermostat up to 85 there was no start or atempted start. I did my usual by turning off the power to get a start which worked as usual. The
thermostat test above I don't think I will be able to do until tomorrow. Let me
know if the above test requires the thermostat test.
I have changed the batteries in the stat and will try jumping the terminals
tomorrow. Will report to you then.
OK will do the jump test tomorrow. Meanwhile think about how the water
drain line to the sewer would effect our problem if clogged.
My thermostat has terminals RC(red wire) and W (white wire) I assume
you wanted me to jump the red and white wire. I did jump the red and white
which had no effect . While holding the jumper in place I tried my power
off and back on trick and got a re-start. As soon as it started I pulled the
jumper and the furnace shut down.Meanwhile the inducer motor keeps
Is the inducer motor relay soldered to the board or is it a plug
You are 100% sure it is the board ?
OK I am on my way to pick up the $165.00 board. Will report back to you
after it is installed
The board is replaced and everything seems to be working, I will confirm
after a few more cycles
