Rheem help needed
Imperial 80 plus. Model rgde-12rajs. It's an old unit. Unit fires and turns off. After running 3 cycles it shuts off and does not fire. The fan also stays on when no heat commands are given even when the thermostat is unwired. Any ideas ?
Must add I did get it to run for a few hours but after reaching the thermostat temp is shut off and has not run properly since.
Generic awnser: Call repair company and pay for service call.
For real awnser: You can get hurt working on your own furnace.
Thats got to be late 80's or early 90's, I would have the thing checked for cracked heat exchanger before I would spend any money on it.

My guess would be that he is correct. Sounds like cracked HX. Time to replace.
