I have a Rheem/Ruud furnace, model number IOEBRJR 115V 9.5 amps. I know this is crazy but for years, yes YEARS! our furnace will stop kicking on. I take the panel door off (and then replace it) and I hear the furnace try to start (the fan comes on)... I have to giggle the wires until the ignition switch kicks on, and sometimes until the gas kicks on too. I've lately been told that it might be a grounding wire problem. Has anyone else heard of this problem? How do I fix it? Please any help would be most helpful and might help me from going postal!

It might be that the unit has a switch on the door panel that you are activating. Lots of units will not run at all if the door switch button is not depressed.

No there is no switch on the door. It only starts once I giggle the group of wires for about 5 to 10 minutes. I thought that it was a broken wire and that the giggling was making a connection but someone told me that it was actually a missing ground wire? Where should it be? Do you have a diagram for this model number?
