JGBS21DEMB General Electric Range - Instructions

removed bottom of oven.removed heat shield.i
then unscrewed the wire nuts to the igniter.i
then tookout the burnner with the igniter attached.
i unscrewed the two screws holding the igniter
in place,and put the new one on.i then screwed
the wire nuts back on,and put it back togather.
it works great,thanks for the help.it saved me alot
of money.

Removed the two screws that hold the oven bottom to expose the glow element. Also removed the lower draw to get to the connections. The job was only complicated by getting to the two bolts holding the glow plug to the oven frame. Getting them off and getting the new plug on was not easy with standard tools. There was not a lot of room to work the hex bolts and i wound up cutting the old unit out and attaching the bolts to the frame and cutting slots in the new unit so I could slot it in. That worked. The glow plug was the problem and the oven came right on.

I put it in the same way tuck it out

This gas range had an oven that would heat, but it wouldn't hold it at a stable temperature. Say you set it at 300 degrees. Well, it'd head up to broiling temperatures, then drop down to like 200 degrees, then 400 degrees (You get the picture).

My guess was that the thermostat, given that this oven was ~20+ years old, was no longer able to detect correctly the temperature inside the oven.

The thermostat sensor is made up of the housing (The part that sits behind the oven temperature control knob), a long wire (so you can route it to the inside of the oven), and the probe itself (Which I boldly assume is the thing that measures the temperature inside the oven)

TL;DR:

-Pull oven from wall.
-Turn off electric and gas.
-Remove the grates and drip pans off the top.
-Pry the range's cooktop up (It's on like a hinge and is designed to lift up. You have to play with it a bit with like a screwdriver on the sides (One on each side). If you pry just a tad, you'll notice these prongs that act like detents. (LIFT CAREFULLY, the heating elements are still connected via their gas lines! They're flexible, but don't man handle the thing!
-Once that's up, it's time to finally start removing the thermostat which is the knob that controls the oven temperature. Pull the plastic knob off which will expose the two screws you need to detach it from the oven (Phillips head). Be super careful. You don't want to drop these screws. You'll be struggling to fish them out of the empty space that sits between the thermostat and plastic knob.
-Once that's loose, open the oven door and detach the thermostat from the back of the oven. Recycle the prongs holding the old thermostat sensor for the new one.
-Go to the back of the range. Like the actual back part of it.
-Frustrate yourself with pulling out the thermostat through the route it's been put in. It's difficult to route it through the tight spaces, but not complicated. Keep a mental note of this route and copy it with the new thermostat that you have to install.
-Don't fret, when it comes time to wire the new thermostat sensor, it's actually a lot easier than you would think to find that little hole in the back of the range that you have to slot it through. It's just slightly covered by insulation. Pulling it slightly aside, you'll see it very easily.
-Screw in the thermostat housing at the front of the oven.
-Frustrate yourself again by routing the wire while taking care not to bend the probe (This is my assumption not to bend it and I think it's a safe assumption to make)
-Find that tiny little hold in the back of the range again, insert the probe through it, then use those recycled prongs to hook that probe into place.
-Yay, you're almost done.
-Reinsert knob on thermostat.
-Turn gas and electricity back on.
-Give it a test run to see if you did it right.
-if it still doesn't work, then it might not have been the thermostat giving you problems.
-If it does work, put everything back the way it was.
-You're done.

Followed you tube instructions I found on line via parts select recommendations.

After removing two layers of the oven floor I could not get at the igniter's wire connections. I found out that the new igniter was shipped with two wire nuts made of porcelain instead of plastic, so they were heat tolerant. Because of this, I was able to unscrew the original part and just cut the wires. I then installed the new igniter and spliced the wires of the new part to the cut wires that lead to the old part using the porcelain wire nuts and tucked the connections out of harms way. It worked fine.

First shut down electric power to oven. remove
oven racks and botton tray. Removed boiler rack and door. Next unscrew 2 bolts holding igniter. remove nuts or cap for two white electric wires.
installed new igniter, hooked backup wires. replaces racks and tray and that was it, job done.

This web site is awesome!!! their forum told me what part i needed, and they shipped it out, super fast, i couldn't hardly believe it! I tried using the Sears Parts web site for my "kenmore" oven and that was a joke, seriously! no more kenmore for me, thanks. It took this site to figure out that i really had a G.E. with a kenmore name on it.
I found out that even though the old ignitor glows well, it may not pull enough amps to open the gas valve.
First i disconnected the two wires on the gas safety valve that lead to the ignitor. These are accessed after taking the bottom drawer out. Then using a nut driver, i took out the two screws holding the bottom of the burner tube. Then inside the oven, i took out the racks and then the two screws in the back on the bottom. Then took out the bottom plate. I removed the one screw on the front of the burner tube, and removed the burner tube with the ignitor attached. I cut the wires off the old ignitor and attached them to the new ignitor with the supplied ceramic wire nuts. I attached the new ignitor to the burner tube and put everything back together. The bottom screws on the burner tube were very difficult for me to reach. Almost impossible to get both hands there to do the job.

Straight forward as per instructions. Removed old igniter, replaced and tested new one and it worked. However, the gas oven would not turn of. Valve may be defective. Knob control is not stripped and turned to full stop. Troubleshooting continues. Part(s) and instructions worked perfectly.

Simply put the new knob on and it worked perfectly. No tools needed. So glad to locate this website to purchase knobs that fit my range.

Followed the enclosed instructions

Go to utube videos for this are there

I rempved the top and bottom doors, than the wire rackes followed by the bottom base of the oven. Then I removed the burner cover plate so I could get to the igniter.. I removed the cover plate for the wiring (2 wires), unpluged them, removed the igniter (2 screws). I had to cut the wires on the old igniter and couple the ends to the new igniter and then replaced everything by just reversing all that I did. Simple! Easy!

Unplugged the oven. First i removed the 2 screws from the pan at the bottom of the oven and took the pan out. Next i took out the drawer underneath and took the screws out of the pans below to get to the ignitor. Unscrewed the ignitor and cut the wires below it to splice the new ignitor on. Spliced the two sets of wires and put the ceramic wire nuts on. Replaced the top and bottom pans and put the drawer back. plugged the oven back in and started the oven right up. Pretty easy.

Most trouble I had was removing the screws that were located under the bracket. I had to slip the oven door off first to give me more room. Very hard to get to these screws because of where they were located under the bracket. I had to twist and turn the old igniter to get to it. When finally removed, I replaced the old igniter with the new one using my own screws. I twisted the wires together, and replaced the baffles, the oven floor, and then the door. The oven fired up wonderfully! Thank you for your prompt service for getting me the part quickly and correctly.
