Hey Tech,
Can you verify the serial number of this Henny Penny OFG322 unit?
Thank you for your time

What letter is after the E-20? That will help to determine if it is related to the blower and air switch or if it is related to the pilot, flame sensor, and ignition module.

Hey Kevin,
From Henny Penny: “That is then indicating that the air switch is opening up, the combustion blower motor has an internal thermal limit built into it, it is possible that it is intermittently heating up and causing the motor to shut down. This could be the root cause and also make sense as it appears to be the one part not yet replaced. I would also suggest inspecting the baffles in the rear to make sure they have not burnt through creating extra heat in the rear.”

I went on it yesterday afternoon with the e20b code, This time it would keep alarming on the e20b code and the flame was acting a little lazy. I pulled the motor assy off and found the blower wheel was packed with soot. I cleaned it and the heat duct that it pulls thru. It seems to have taken care of it. The flame is acting like it should and working properly.
