A slow green means normal operation. A slow amber means normal operation with a call for heat. You don't want the red on as it usually indicates a failure. Have to leave for a bit today, but might want to try bypassing the thermostat. To do this, turn power to furnace off, go up to the thermostat, take the front section off, loose from the back. Locate the wiring and take and twist the ends of the red lead on R and white lead on W together simulating a call for heat.

Just green which blink like 16 times
And the pasue for a few second
Expert:  Tim H. replied 3 months ago.

Check at the board for 24 AC volts between C and W with door switch pushed in. This is with R-W jumped at the stat.

Ok i will i am?not home right now
Customer: replied 3 months ago.
If there no voltage ???
And if there is voltage
What next
Expert:  Tim H. replied 3 months ago.

No voltage, then next step, check R-C. If 24 volts there, but not at C-W, then it is bad wiring between stat and furnace.

Customer: replied 3 months ago.
With R& W jump out
C&W with switch closed there 27 V
Customer: replied 3 months ago.
The fan can run but the furnace never turn on
Expert:  Tim H. replied 3 months ago.

What are the LED lights doing with a call for heat?

Customer: replied 3 months ago.
The Green led blink slowly for about 16 times then there about 2or 3 second pause
Expert:  Tim H. replied 3 months ago.

It sounds like a bad board then. Because with 24 volts from C to W, you should get a slow blinking ***** *****ght, call for heat.

Customer: replied 3 months ago.
There no ***** *****ght at all
Expert:  Tim H. replied 3 months ago.

The board should not flash 16 times. There is no such fault code. I recommend a new board.

Expert:  Tim H. replied 3 months ago.
