How many times is light blinking on circuit board when this happens?
Solid red light means normal. Or thermostat is not turning on the furnace. Run until it shuts down and see if light blinks....
I will wait.
Thank you....do you mind removing the thermostat?
we want to take the wire from R and the wire from W and twist them together direct. Thi will bypass the thermostat and tell us which way to go.
I have twisted the red and white wire. What's next?
What is the furnace doing now that red and white are connected?
and the light?
Ok, turn switch off on side of furnace...in front of the burner on the left side is a metal rod with a white ceramic base...use a piece of steel wool and clean that rod. Then turn power back on....leave r and w twisted for now...
If you have a solid light still and unit is not running it will most likely be a bad circuit board.
Here are blink codes
When a fault is discovered by the system the LED will blink in the following manner;
Steady "OFF" - No power or internal fault
Steady "ON" - No fault found - unit functioning properly
1 Flash - Failed ignition or flame drop-out
2 Flashes - Pressure switch open with flue venter running
3 Flashes - Pressure switch closed with flue venter off
4 Flashes - Main limit switch open
5 Flashes - Flame detected with gas valve closed (de-energized)
6 Flashes - Compressor output delayed from short cycle/staging timer
7 Flashes - Fault detected in 1104-1 operation
Since your light says OK...but it si not running leads me to bad circuit board.
