That would be one that I haven't seen.

This reminds me of the 50's TV show "what's my line?"

Look at how good this famous star looked in those days....

If you are facing the unit, is the flue over on the right hand end, where the gas line comes in, OR

is it in the middle, with the gas line, right in front of you as you face the unit?

Is the unit a light green color?

no serial available

thats what i was thinking also, no i assumed pressures were ok. i will check it tue. assumtion is the mother of all ****ups.

Did you get a serial number?

yes this a gaspack rtu. no I did not get any pics. most likely i will be back there on Tue. I can snap a few then.

pilot should remain energized in the sequence. You attempt checking/setting pressures?

When you say "on" a commercial building, do you mean this is a rooftop unit? Did you take a picture?

the more i look, I am not finding this model # on line. the tag is bleached out and this # was written on unit above tag. could this be a 584apo?
it is 3 phase

This is a commercial unit??

White Rogers Ignition module

I am working on a Payne m/n 584apw048080aa?g. I had an ignition problem with the orignal ignition module g770ngc-7. I installed a white rodgers module 50d50-843. followed the wiring diagram,added a burner ground, installed the green C chip. the ignitor sparks, lites pilot, main gas starts and shuts off pilot, no flame, main shuts off and restarts cycle. i have had this same problem with a Carrier furnace, tried a Robertshaw mod then a White Rodgers and both acted the same. is there something i am missing? is there a trick that is not in the paperwork?
