Lennox PS 40 FS Dies After Startup

I have a friend that just got a used PS 40. Very nice quick flame during startup phase. Flame dies down to almost nothing after startup though. The auger does not appear to be dropping enough fuel. It runs for 3 seconds off 5 seconds. We jumped everything and even pulled the auger for inspection. I'm guessing the control board. At 441 retail they must be made of Gold!!

Any Suggestions?

Should we try oiling or greasing the auger motor? Thanks!

make sure the TSTAT poles on the control board are jumped (connected) and the unit is calling for heat.

Will do! Thanks!

He does not have a thermostat and is planning on using it in manual mode for now.

Jumping the t stat terminals did the trick! Unit is Fixed!!

Thanks Everyone !!
