I feel like I am in the middle of an inside joke with the flame sensor picture (mentioned by KC13) and $$$$$.
You are but do not tell anybody. LOL

I recognize that I am not the most keen person around but I cannot find the flame seņor. I found the ignitor but not the seņor. But I did jump the R & W terminals and the furnace came on. The furnace would light up but only for a minute or so, then cut off. The blower would continue to run. The furnace tried to light 3 times then shut off completely.
I hope I explained everything clearly enough.

There is a flame sensor somewhere. The book calls for
Microamps of flame circuit (1.0 minimum, up to 7.0 better)
Also check continuity of the ground wire.
Rheem Rudd same basic furnace with name change has had problems with this unit of yours. Last report they were offering 375.00 towards a new furnace but if it is on LP gas and not Natural gas the furnace can be had for free with the right arm twisting. That you would have to take up with a local Rudd distributer.
I believe your unit might also be the drum design and that unit was just plain bad news. Can you post some pictures of the burner area? If so I can probably locate the flame sensor if so equipped.

If it's the Imperial Drum design, there is no OEM remote sensor. The ignitor does double-duty on this one, unless an add-on remote sensor has been installed (look for a wire tap on the harness to the ignitor). Imperial... yeah, right.:rolleyes:

There were two reasons to ask about the drum. The sensor since he could not find one and the cracks in the drum for 375.00 I believe. If he has no sensor and if the furnace was not changed over to the new style ignitor/modual system by now it is probably best to replace that POS.

POS is putting it nicely. There's nothing "Imperial" about those drums. "Inferior Drum" would be more appropriate.;)

Okay,
After a cold night of sleeping I woke up this morning and examined the furnace some more. The furnace goes through 5 cycles of lighting then shutting down completely (I realized that late last night). A guide on the control panel door said that it could be one of two problems. The first being the control board needs to be replaced. So I took the screws off the control panel doors and low and behold in the upper left corner of the control board there was a brown/burn mark that appears to be a fried portion of the control board.
So I am thinking that I need a new control board/panel.

Need to know if this is indeed an imperial. If so, replace furnace. How old is furnace, they haven't made imperials for quite a few years. It may be time to call in a tech to assess the furnace. The board definitely sounds like a problem, but I hesitate to tell you to replace board when there may be other issues with the furnace. Could become a money pit(especially if its an imperial). Please let us know what you decide.
Ps, the new rheem/ruud furnaces are much better. Don't be scared of them for past mistakes. All furnaces have had their bad years of manufacture. If you decide to replace, just gets at least three different quotes from reliable contractors. Hope all works out for you.

F.Y.I. I checked on a replacement h/x drum in November and was told they are no longer available. For the few that are still in warranty, the manufacturer is offering a minimal credit toward a replacement unit (must be same brand).

Does the center area of the furnace resemble a large, round, bolted horizontal bulkhead?
