36274224302 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.

Easy

remove old burner, put new in place

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

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 repair went easy the tube was a perfect fit

Unbolted the old parts, cleaned the stove, and bolted the new parts on. Looks just like brand new!! The parts were perfect, easy to find, inexpensive, and delivered quickly!
Thank you!

Start by removing all screws 3 for each burner total of 15 t-15 bit is required then proceed to remove spark igniters 5 total slight pull next step would be to slide a screwdriver under top left and right side to remove top shelf. There you will have access to the parts you need to replace. When done just reverse installation instructions to complete

repair was easy,couldn't believe I found parts. Bought house with stove in it.wife wanted new one,replaced broken parts cleaned up oven saved 600 bucks.

changed old burner tube , with new equipment. thanks to PartSelect.

I removed the two nuts that secure the rear orifice tubes. This allowed me to lift the range top to access the broken tubes. Once lifted I removed the nuts that held the broken orifice tubes. I then connected the new orifice tubes. I removed the three(star)screws that fasten the orifice brackets under the range top. Doing this allowed me to connect the new tubes without having to maneuver them at all. I then lowered the top just enough to reattach the brackets. After securing the rear tubes I snapped the range top back into place. Just remember, if you use propane for cooking then you must remove the brass orifices from the old tubes and place them in the new ones. If you don't do this then your flame will not burn properly. Simply unscrew them from the old tubing and put them in the new tubing.

Simple to correct 1. lift off grate 2. lift off burner cover 3. lift off old burner. 4. replace burner, cover and grate. took 10 seconds. burner works perfect

Opened up the top of the stove using a screwdriver. Lifted it up about 3 inches and legs popped out on each corner and held it in that position. Traced the wire to the back and down to the oven. Pulled new thermostat along that route. When I got to the back it was a little tricky moving the thicker end around and down into the hole without removing anything from the back- but I did manage to do it. I then unhooked old thermostat from 2 clips, inserted new one and then went to the front and unsrewed the 2 small screws behind the oven control knob. Magnetic bit on screwdriver is a must! Pulled it back and removed wires one at atime and put onto new unit, then screwed it back in place and replaced knob. Plugged it in and turned it on. It came on ,stayed lit. Turned it off and it stayed lit- surprised me. . . . . . 25 Seconds or so and it went out. . . . . Job done!!

Husband actually did the repair, It went really well except he forgot to remove the heat shield from the old part to attach to the new bottom. (His mistake!)
