Loosened two screws and removed tray, very simple. Replaced new tray and adjusted screws to hold tray. Easiest part was finding new tray part number and ordering replacement using online parts diagram.
The old part, including lightbulb and socket, had corroded into place, and the glass light cover was stuck to the socket. I used a dead blow hammer and a dowel just under the diameter of the hole to tap on the back side of the socket to loosen it and get it out. The metal tabs on the old socket were folded back to make it fit better (?), which made it harder to remove. Lots of muscling of the part to get it out. Easy to install new part once old one was out of the way. An experienced person would have removed the old part and installed the new in no time.
Turned off power to range. Removed the lower panel that was secured by two screws, as well as the metal cover beneath it also secured by screws.. Removed the two screws securing the igniter, and pulled apart the black tubing that secured the igniter. (I had to pull hard to get it apart). Plug the new end into that same black tubing. screw in the two screws to secure the new igniter (this is tricky because one screw is hard to reach) I laid something in the base to cover the holes so I wouldn't lose a screw if it dropped. Screw metal panel back in, followed by the lower oven panel.
The hardest part was taking out original light bulb because screws on shield where hard to unscrew after all this years . The old bulb vent out leaving neck in socket. It took narrow electrical pliers to get neck out .The generic appliance bulb did not fit and had aluminum neck ,not recommended for brass sockets in ovens.Putting new light bulb in was not the problem.
door of oven came apart when plastic screw holders broke
put back together with parts ordered. Parts arrived in 2 days!!!! and saved my large dinner party the following day from being ruined. Thank you so much for your parts inventory and for Jenn Air supplying only the part needed and not the entire door. It was a life saver!
