Is my Beckett burner's squirrel position causing "no start" my boiler?
My boiler (Utica SHF 5175 WT) sometimes won't automatically start up and stays off. Reset button also won't fire it up. I have figured this much... when this happens (no start,): I switch power off, open at where the CAD cell sits where I can see and access the squirrel wheel of the Beckett AFG burner, then using a screwdriver or something to change the position (rotate it a little) of the squirrel wheel then close it up, power switch back on and then reset will start the boiler.
The squirrel wheel seems to rotate freely (i don't feel any binding.) But somehow when the boiler had stopped and the squirrel wheel was at certain positions, it is preventing from restarting ??
I don't know why boiler won't come on at certain positions of the squirrel wheel... Any idea what' causing this? Do I have to replace the Beckett burner or is there a simple fix? I am okay with opening things up to figure and fix. Can someone please explain how the AFG Beckett units operates?
