Here is what the service guy said was stuck. Jim said that he watched the guy and they could not get it off.
Jim said that yes, the igniter does glow, he does smell gas when it turns on but the pilot is not lighting. In order for the furnace to flame up, he needs to bang this with a wrench.
oh and the guy did not charge for a service call when he came out. I did ask my husband why we do not get another guy out and he said that he did see the guy, as well as himself, try to remove this piece and believes the guy is telling the truth.
whatever. I just want heat like a normal person. Thanks for any help!
