Hello, I need the brand, model number and approximate age of the furnace.

Next tell me a lot about your technical skills level, if you are up to doing some trouble shooting, post a clear, well lit, well focused, close up photo of the wiring diagram glued to the inside of the blower section access door... you can use the paper clip icon at the right end of the tool bar above to do that.

We can go from there.

OK, furnace is about ten yrs old, it is a AIRE FLO MODEL NO. AF80MPA07583A..... I just changed over to GAS it was propane... replaced flame censer...... furnace will run for about 3 to 5 minutes then flame goes out... the light code is 2 blinks poss 6 blinks.... something about pressure valve........ there are three censers contacted to this, and they are connected by purple wires connecting all three together.... one is just above ignition.... one just below ignition.... and one is on the left side just below far left burner. ..... I believe the one about ignition is bad .....

Thanks, ***** ***** a photo of the wiring diagram so I can mark it up with trouble shooting directions.

Just so you know, the wire colors are arbitrary, only the wiring diagram will work.

Tell me if the burner flames are impinging well on the flame sensor rod(s).

We can go from there.
