More 1201LRIM problems

I am still waiting for new fans as per this previous post

But now it is being difficult on another tack:

It frequently won't light on propane. We can't go to bed without being awakened by "beep beep beep" the read out shows "No Fl" and it will not relight. Yet often (not always) during the day we put it on propane to reduce the current draw so the AC will start. (We are in Mexico with less than optimum voltage stability) It will often (not always) run all day on propane then in the evening "beep beep beep" again.

The burner is clean--I had just vacuumed it out. :h

That will have to follow the Prosine 2.0 trouble shooting! For the moment its running on 120VAC via a separate 15A outlet and extension cord.

Also, when you work on the control board, you HAVE to remove the Spark electrode orange cable connection. If you do NOT use a back up to hold the Piezo in place when removing that spade connection you risk breaking loose the soldered connection for that Piezo tower on the circuit board. One result of loose/broken solder connections is either lack of spark(weak spark) OR lack of flame sense because of the loose intermittent connection due to the solder. If you can "wiggle" the Piezo tower on the board, remove the board and resolder the Piezo connections. Doug
