Replacement thermal cut-out

Thermal cut-out let go in this toaster oven after 21 months of use.  KitchenAid won't sell me a replacement part, but is willing to sell me a new unit for $112.95 with shipping.  Country of origin?  China. 


Basically, it is a 206 degree centigrade thermal cut-out p/n 155431.056 and has a single screw mounting point.  It's an electrical part (obviously) and has two spade terminals on it.  The main body is ceramic and is about 3/4" by 3/8".  There is an aluminum piece that is crimped on like a jewel at 4 points, and provides a cross-like contact surface of about a little over an inch by 3/4". 


What I'm looking for is some kind of thermal cut-out of the same or slightly lower cut-out point that I can retrofit to this unit.  Electrically and mechanically, the oven is in excellent shape and was never abused.  In fact, it still looks new.

Oven keypad is completely black but inside oven lights work. does keypad have a separate fuse?

Yes. Many of these have a display thermal fuse that is part of the wiring harness that connects to the board... it should have continuity. WP4451042. Almost all models have what is called the "oven shut-down thermal fuse" which is on the back of the machine ( you have to pull it out of the wall and remove the back panel) and looks like this KitchenAid Range Stove Oven Thermal Fuse WP9759242

Noisy fan and no heat

Kitchen aid is made by Whirlpool. There is a very good chance the then thermal fuse on the back of the oven has tripped. Whirlpools are very prone to this fuse tripping after a clean cycle. The noisy fan is just that a noisy fan it will probably need replacing. I have replace a couple of them over the years. When you pull the oven out to replace the thermal fuse replace the fan motor at the same tiome.

It is a free standing kitchen aid oven. I put it on quick self clean and it said it would end at 2:00. The panel went blank at 1:20 and it is past 2:00 and it is still locked. I checked the circuit br

Unfortunately KitchenAid ovens notoriously blow a thermal fuse when you use the self cleaning cycle, and if you're lucky that's all that happened. Hopefully your oven is still under warranty. If so, call KitchenAid customer service and they will repair it for free.

If you're handy you can check/replace the thermal fuse yourself (requires pulling out the oven and taking off the back panel, finding and replacing the fuse- be sure to turn off power and gas first).

I have a KEBI17DBL8 Oven that will not work after using the self clean cycle. Should I get the thermostat replaced or but a new oven?

No, no need to get a thermostat or replace the unit...yet.

sounds like a tripped hi-limit thermo.

that model number looks like a double oven wall unit, correct ? if so, big job. if not awesome. if it is, it's hard only because these are heavy. (alot of techs like myself have "wall oven carts" that allow me to remove it fairly easy) you might not have to pull it out though if it's not a wall oven, my bad.

however, I think it may be the older unit's manufactured by "Dacor". if so the limit switch on most of those ranges is a "non-resetable" style. meaning you'll have to replace the themal cut-out or aka thermal switch.
*FIRST, unplug the unit or shut off the breaker.
the hi-limit is located by the latch/lock assembly, so you'll need to dismantle the unit to a degree. if it's a free standing range, it's pretty easy. lift the top and the latch/lock access panel is located right there.

you'll need to determine the "why" as well of course. did the cooling fan/blower fail (#4173004), or the cooling fan therostat (#4173008) ?

the part number you'll need for the thermal switch failure replacement is #814505. check the old one by ohming it out first of course.

hope that helps,

good luck

KEBS 278 DWH6 After self cleanng (Top oven) everything shut down. There is still power to the ovens and I have shut off breaker for a long time to see if computer reset. I read that the problem might be...

The thermal fuse is in back of the oven. This is a design flaw of the oven KitchenAid won't admit. Everytime you use the self clean feature this will happen.
The oven has to be taken out to reach the fuse in the back and replaced. The fuse costs about $40+, but the labor will probably run around $300+ unless you feel confortable doing this yourself.
I am about to replace mine for the 2nd time, good luck!

No power and door locked after starting self cleaning cycle

Thermal fuse went out by door latch and thermal fuse on back of oven probably tripped too; once failed they need to be replaced. This is probably a job for the repairman as something caused fuse to go out in the first place; unless resolved it will recur. Please contact me if you need further help or leave feedback if appropriate as that is how I get paid. Thanks for letting me help you!

You have a thermal cutout, usually, behind the back access panel, which is known to cause this problem. It may or may not be resettable but I recommend replacement either way.

Error Code F5 E5

The repair on this issue will be one of either of these parts.
It is a common issue with Kitchenaid wall ovens.
