Happened today after I was trying to start again furnace
6 years old
Honeywell SV9541M "smart valve"
It would not start burner, valve klicking sounds coming and going.
In the intervals beetween every attempt green light flashing 6+2 times.
Any advise?

Probably gas pressure, but could be bad valve. Does piolt light?

probally gas pressure, but could be bad valve. does piolt light?

Yes it does. Actually after shutting down completely ( Switch off) it starts but only for 2-4 minutes and stops again.

Is it Valve?
Should attempt to replace on myown or call for service people?
