J2S968KH5CC General Electric Range - Instructions

Replaced burner gaskets.

Turned off power to range, slid range out from counter, removed convection fan cover, removed convection fan blade, removed back of range panel over convection motor, removed motor, put in new motor, put range panel back on, put new fan blade on front of motor, replaced fan cover, turned power on. No more clunking noise from motor.

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."
