I have a payne furnace model 340MAV, after the inducer motor

Customer Question

I have a payne furnace model 340MAV, after the inducer motor starts, the flame does not come on in the burner assembly while looking through the sight glass. A while later the inducer motor shuts off and of course the blower will not come on due to no heat in the combustion chamber. What do you think may be the problem...

great. down in the blower section is a circuit board, that board is telling you a code. that code will help us diagnose the issue. When you remove that door to the lower section, it may have a "door switch". that switch will shut off power to the furnace, so you will need to press that switch to get the code.
