- In this video, I'll show how to check an operating thermostat on a clothes dryer while running. This test will verify that the cut-out and cut-in temperature points of the thermostat are within spec.
For anyone who wants to learn more about clothes dryer with its controls, how to check them, wiring diagram and the location of parts related to the wiring diagram, that video is located here.

One of the weak points to our kitchen oven is the thermal fuse, which is located in the back outside of the cabinet. When it blows, you need to replace it for about $60 each time. I've replaced three so far, and now we never do self cleaning because it's a weak point of the design. I've often wondered if it would be safe or possible to swap in a resettable fuse that trips out at the same temperature. The only downside I see would be the possibility that in a fire the oven could restart as the fire cools down, but that seems unlikely. What do you think? Are resettable fuses more expensive?
I know you weren't asking me but I would try to figure out what's causing it to blow. Thats fairly unusual but if you could find a manual resettable fuse that's the same spec I dont see why not. Ps I dont think its going to self- reset. You've got to manually reset it So I wouldn't worry about it going back on by itself
Hi Dave! My thoughts are exactly the same as samlol23 who posted a reply to your comment. I would like to know why is it blowing which is obviously because of high heat or excessive current since some thermal fuses are rated for current also. Maybe its due to its location. I would monitor the temperature and current while using the self-cleaning feature and disable the function if it starts getting to the point of where the fuse is going to blow. I don't see any reason why a re-settable thermostat couldn't work as long as the temp and current are similar. And I don't see a problem with a fire since when the thermostat opens, the range will have to be restarted to allow current flow. Personally, I told the wife not to use the self-cleaning feature as it's more trouble than its worth. You have about 1,000 degrees inside of an oven for about 3-5 hours. I've seen in the past where inside panels will warp, the door warps creating leaks around the gasket and puts a heavy strain on the heating element. And for that thermal fuse to cost around $60, it obviously has some gold in there 😊Good luck on what you find and maybe do a video if you get it resolved. Take care Dave!
@@stuzman52 Thank you Sam and Terry. It's a known flaw in the design of a Kitchenaide oven, and about ten years ago I did a video showing how to diagnose and replace both fuses. Engineers designed the system with no cabinetry surrounding, so they didn't anticipate the way temperatures spike if there is minimal air flow in an enclosed cabinet. It was another example of what can go wrong when bench testing meets the real world. I like Sam's idea of a manually re-settable fuse, even if it means having to pull the oven out just to press a little button. An automatic reset would be even better. On the other hand, that single device is all that is standing in the way of burning the house down. Maybe the wise decision is to do as I've done, shrug and never use self cleaning, ha ha.
@@spelunkerd One other thing that I thought is to install maybe two fans like used in computers to exhaust the air from around the thermal fuse. Just throwing out some ideas for you. Have a good one Dave!
I just reviewed your video on your range from years ago. I believe that the thermal fuse, #4452223 replaced with #9759242 isn't a thermistor. It looks just like a normal thermostat using a bimetalllic contact. And the idea that I mentioned about installing a couple of exhaust fans would be useless since you already have a large cylindrical fan across the back and two other fans on the back of the unit. Your biggest issue is where the gasket wasn't sealing on the top of the door which was allowing this 1000 degree air to be pulled into the front intake ports. I've seen this on a lot of ovens with the self-cleaning feature and even the door will warp not sealing around the gasket. I really don't have a good answer for you Dave with that issue. But, having an exhaust fan to pull this air out of that compact area behind the oven would have to help. Have a super great day!
