36272286890 Kenmore Range - Instructions

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.

I bent the tubes very slghtly to rech the area of attachment. I first screwed them with my hand then tightened them with an adjstable wrench. It was really simple and fast.

the electrodes on this model have to be removed before you can raise cooktop, once cooktop is raised remove wire from burner bracket, use needle nose pliers to squeeze bottom of clip,remove &replace with new parts.

I put it in the same way tuck it out

My son lifted up cooktop, unscrewed the front plate to gain access to old tube burners, removed and replaced with new parts.

Easy

Remove the old tubes. Lift the lid NO MORE THAN FOUR INCHES. !!!!! Feel for the connections on the switch ends and attach losely. Carefully ( with some slight bending ) attach tubes to the burners. Tighten all connections. Do not over tighten.
The tubes broke originaly because , attempting to clean the area I lifted the lid too high.

The part that was ordered based on the shamanic wasn't the part that was needed for the repair. It was to short. I took the other screw for the other side and that screw was an inch longer than the screw that was ordered thru your company. I then went too a jar that I placed extra screws, nuts and bolts which l keep in my garage . I found a same length screw but a different head and it works perfectly fine. When I ordered the part from your company most of the parts did not have a photo of the part on file, or a description like how long the part is. I still ordered it because it should fit the make and model number that was posted on the shamanic that was showed to me on line.

Unplugged the range. Took out all the necessary screws and lifted up the cooktop cover. Unscrewed each gas tubes connecting to each gas burner's dial to allow more working space. Pulled out the old thermostat, installed the new one. Put back the gas tubes and all other necessary screws. Plugged the range and tested out the new thermostat.

Replaced the oven thermostat and calibrated the new thermostat by adjusting the temperature setting knob. Instruction I found on-line were very helpful and the repair was moderately difficult. Trickiest part was threading the new thermostat into the oven. Total repair time about 1 hour.

Cut off the power. unscrewed the cover. fed the new thermostat inside the over and rescrewed. Feeding the line was the most time consuming finding the hole to insert it in the back of the oven.

Received the parts very expeditiously(2 days from time of placing the order), and the replacing of the caps was a "no brainer".

loosen the compression fitting both ends and screwed new ones in place .

Unplugged stove. Removed the top rear panel to see where the thermostat cable fed into the oven. Left the current cable in place and fed new cable along side the old one. Pulled out the old cable once new one was installed. Attached wires to new thermostat and installed. Turned oven on to test. Everything went great.
