PB910TP1WW General Electric Range - Instructions

Convection fan came loose from the shaft with a lout rattle and grinding as the fan spun down. Had to remove four metal screws to remove the fan cover. Initially tried to just put the nut back on to hold the fan. However, I could not get the nut to start, so I assumed that threads were stripped on the nut or the shaft. Ordered the replacement nut, hoping that it was the nut that was the problem. However, I had the same problem with the new nut. I could see no damage on the shaft. It finally occurred to me that the nut and shaft had left-hand threads (counter-clockwise to tighten). At that point, it was extremely easy to put the nut back on and tighten it. I did not try using the old nut, since I had already received the new one, but I'm certain that if I had come to that realization earlier, I could have saved time and money. So, if you have the same problem, try putting the nut on "backwards."

Changed out the burner with a new replacement and it still didn't work. The socket on the old burner had a burn mark on it. The infinite switch operated sloppy not crisp like the other burners.Ordered a replacement online. Moved the range away from wall and cabinet and shut off electric at panel box. Removed upper back panel. removed switch knob and 2 screws holding switch. Compared electrical connections of both switches and saw that they were different. Read instructions which were included with new switch and found diagram for connecting old lead to new lead correctly. After all leads were connected, remounted new switch powered up and tested OK.
