Miller MMHB-070ABHR-06 mobilehome gasfired - won't ignite
Our Miller model won't light up - intermittently. Came home to a 45 degree house and service call resulted in new electronic module and igniter. Next day same problem. Different tech - couldn't fix it, but suggested buying an oil burner! Has happened twice since, and was able to start by turning 'stat down to 55 and up again.
3 flashes on the module says: "gas valve error; false flame sensed during warm-up; control will return to normal oper. and repeat ignition when false flame is not present."
Checked forced draft fan, amps OK at .8. [The tech. tried to sell me a new draft fan!]
I haven't a clue! I'm afraid to leave the house for more than a couple of hours.

I have the same problem with no flame sensor. Mine is a Miller CMF 80 PG CONV about 5 years old.
