Do you have the full model number of the unit, please?
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.
What are your LED lights doing?
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.
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.
What are the LED lights doing with a call for heat?
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.
The board should not flash 16 times. There is no such fault code. I recommend a new board.
Looks like the board part number is ***** Found one here.
