Bryant Gas Furnace P/N 394DAC03100 about 30 yrs old.
Pilot light stays light and burner going on and off after checking valve problem seems to be some type limit switch when I move the wiring by shaking a little it ignites. Having a problem finding which wires are loosely connected..? If anyone can direct me in this it would be appreciated and where to find parts for this P/N # thanks

Try replacing the 3 wire pilot as the bimetal element my be worn out
