Hello,
I have a York Diamond 80 with the following symptoms:
1. Will turn on and heat normally through several cycles
2. Eventually it will turn on, and the blower kicks on with no heat
and it has to be turned off with the thermostat swtich
3. When turned back on it will work a few more times (cycles) and then
go into the same routine of having to be reset
4. I have cleaned the flame sensor (wasn't bad to begin with)
5. The ignitor was changes a couple of years ago (thinking it was
that..) but the freqency of the failures is increasing
...could it be the curcuit board?
