Ok, I have a very strange scenario that I'm hoping someone here can
help me out with. I have a Beckett AFG that won't stay running. It
ignites perfectly, I've got good flame, but it shuts off about 20-30
seconds after running. So far, I've replaced the ignition transformer,
primary control, nozzle, electrodes, and oil pump. I have a friend who
works on commercial boilers who has been trying to help me and he can't
figure it out either. Does anyone have any ideas? Thanks in advance.
