Hey Dan,

My oven seems to be undercooking food. I checked it out with a thermometer and it's registering perfectly fine. However, I have noticed that I may be placing the food into the oven too soon. The 'PREHEAT' light and signal may be alerting me before it reaches the desired temperature.

What would cause this? The Oven Sensor Assy. part? (Part #WB21X5301) Does that need to be replaced? Or would it be something else? Is there an adjustment that can be made? The Owner's Manual does not address that specific issue, however, it does tell you to adjust the oven temperature by ±35°F. But that's not really the problem. The temperature is fine; I'm just being alerted too soon.

I have a Kenmore Model #911.93578 30" Electric Self-Cleaning Free-Standing Range.

Any suggestions? Thanks.

** Kenmore Model #911.93578 **

That model number is incomplete, there should be another 3+ digits to it.

** My oven seems to be undercooking food. **

What kind of "food" and what exactly are the results (eg. cooked on top but uncooked on the bottom, vise versa, uncooked just in the middle but top and bottom done, etc.)?

What kind of cookware is being used? If metal, is it dark or shinny?

** I checked [the temperature] with a thermometer and it's registering perfectly fine. The 'PREHEAT' light and signal may be alerting me before it reaches the desired temperature. **

** What would cause this? The Oven Sensor Assy. part? **

If the oven temperature sensor was the problem I would NOT expect the oven temperature to be correct.

Dan,

Full model number is: #911.93578891.

The food that I noticed that was not coming out that great was homemade apple pie. Back around Thanksgiving and now at Christmas both apple pies bottom crusts were soggy and the filling was watery. It was as if it was undercooked. Now, after conducting the temperature test, I am realizing that I am placing the pie into the oven upon the sound of the "PREHEAT" signal and the red light appearing next to the word "PREHEAT" on the front panel. Obviously, though, this oven is not up to the desired temperature for a good 10 to 12 minutes more.

So it appears that the oven is signaling that it's reached the temperature before it actually does.

If it's not the oven sensor assy. part, what could it be?

Thanks for your input and fast reply post!

Sincerely,

I'm afraid I can find no listing for that model at the Sears parts web site. Where did you get the part number of the oven sensor?

** this oven is not up to the desired temperature for a good 10 to 12 minutes more. **

Many modern ranges do not preheat to the exact set temperature. Range manufacturers claim it is not needed. I do not know at what temperature the control on your model is designed to heat to on preheat.

Have you checked to see at what exact temperature the preheat light comes on for a particular temperature setting?

** If it's not the oven sensor assy. part, what could it be? **

If the oven is not preheating to the temperature it is designed to (remember I do not know what yours is designed to operate to), I can only think a problem in the electronic control could be responsible.

** this oven is not up to the desired temperature for a good 10 to 12 minutes more. **

Have you tired cooking similar food after waiting the additional 10 to 12 minutes for the oven to get to full temperature to make sure it isn't something else causing the poor results? It might be prudent before replacing the electronic control.

Dan,

Again, thanks for a quick response. You're fast.

In answer to your last post——

**I'm afraid I can find no listing for that model at the Sears parts web site. Where did you get the part number of the oven sensor?**

That's why I mentioned the number as only #911.93578 omitting those last 3 digits. At least that's how I can obtain part numbers on the www.SearsPartsDirect.com website.

**If the oven is not preheating to the temperature it is designed to (remember I do not know what yours is designed to operate to), I can only think a problem in the electronic control could be responsible.**

Well, maybe that is it? In other words, it eventually heats up within a reasonable 10 to 12 minute period. No problem there. It's just that after about the 1st minute or two you get the "Beep, beep!" sound telling you, the users, that it's reached the set temperature and that you may begin baking/roasting; in other words, 'preheat' phase has completed. What I'm saying is that this is way too early. And the Kenmore® Owner's Manual does not address that in the "Before You Should Call For Service" section.

**Have you tired cooking similar food after waiting the additional 10 to 12 minutes for the oven to get to full temperature to make sure it isn't something else causing the poor results? It might be prudent before replacing the electronic control.**

I have a partial answer there. One problem is the recipe itself when I compared it to two other cookbooks. This one cookbook had temperatures set to the lowest. Now, add to that, my placing the food into the oven prematurely before it is up to optimum temperature and I'm sure that was the problem with the last 2 pies that I baked.

Perhaps I should call Kenmore's® Service Dept. if there's no other way to obtain the information. I just don't know if I'd get an actual technician vs. a customer service person.

Suggestions? And again, thanks!

Really?? I get:

"We could not find the information you requested. Our online database does not contain any information on model: ELECTRIC RANGE - 91193578"

** It's just that after about the 1st minute or two you get the "Beep, beep!" sound telling you, the users, that it's reached the set temperature **

As I stated, reaching the preheat temperature is not necessarily the "set" temperature but I do not know the way your range control was designed to operate.

** Perhaps I should call Kenmore's® Service Dept. if there's no other way to obtain the information. I just don't know if I'd get an actual technician vs. a customer service person. **

You will NOT get to speak to a service technician unless you have him out to your home for a service call. The same goes for just about any other service company you call (besides a one-man operation whom does everything them self).

Dan,

Again, thanks for your fast reply.

In regards to: **We could not find the information you requested. Our online database does not contain any information on model: ELECTRIC RANGE - 91193578"**…

…I can say that I, too, receive that error message after it first identifies the abbreviated model # as a bonafide range that they make. If I put tag the last 3 digits on there it won't even pull that up. So I omit them and I get the circle with the black dot in it followed with the words "ELECTRIC RANGE—#911.93578". But then when I continue to search for a part I get the message you stated above. It ends there. I don't know what to think.

**As I stated, reaching the preheat temperature is not necessarily the "set" temperature but I do not know the way your range control was designed to operate.**

I don't know either but let me quote this from my Owner's Manual which, by the way, covers the following model numbers listed one under the other on the front cover: #911.93571, #911.93578, #911.93575 and #911.93576. It says on pg. #14 under 'Kenmore Operation Oven Cooking Tips" under 'TO SET BAKE':

2) The "OVEN ON" indicator light will glow.

3) When the oven has reached the selected temperature, a series of short tones will sound, and the "PREHEATED" and "OVEN ON" lights will glow.

4) The "PREHEATED" and "OVEN ON" indicator lights will remain on until banking is complete and the control is turned to the "OFF" position.

So my understanding is that this signal means the temperature has been reached. An example: set to 350°F and within 4 minutes it signals and an oven thermometer is showing maybe 175°F. It may not reach 350°F for another 6 - 8 minutes.

**You will NOT get to speak to a service technician unless you have him out to your home for a service call. The same goes for just about any other service company you call (besides a one-man operation whom does everything them self).**

Yeah, that's what I thought. Any suggestions? Can you tell from this model who made this unit? GE? Hotpoint? Whirlpool? Sometimes they're made by another company. I think you told me once long time ago and I can't recall that information.

Thanks again for your information and your opinion on this. I may have to live with this until I buy a new unit later. It's working fine…just not heating up completely when it says it is.

** I, too, receive that error message after it first identifies the abbreviated model # as a bonafide range that they make. **

Unfortunately, just because it listed there does not mean it is an actual, complete model number. But anyway, unless you find a listing for your *exact* model number, you can not go by any parts lists found.

BTW. Not all Kenmore models ever made are listed on their parts web site. Some models have to be manually looked un on microfiche.

** 3) When the oven has reached the selected temperature, a series of short tones will sound, and the "PREHEATED" and "OVEN ON" lights will glow. **

Than maybe the control used on your model DOES preheat to the full temperature? I myself have no way to verify that.

** my understanding is that this signal means the temperature has been reached. **

If that's the case and the set temperature is NOT reached but the control does eventually correctly control the temperature at that setting, I can't see the problem being anywhere else besides in the control itself. If there was something else responsible for the temperature discrepancy (like the oven sensor, etc.), the temperature would usually ALWAYS be incorrect.

Dan,

I'm finally getting back to you with some research here. Thanks for providing those links to those websites.

**If that's the case and the set temperature is NOT reached but the control does eventually correctly control the temperature at that setting, I can't see the problem being anywhere else besides in the control itself. If there was something else responsible for the temperature discrepancy (like the oven sensor, etc.), the temperature would usually ALWAYS be incorrect.**

Well, it took a while but I came up with this part here which looks like the part inside the top instrument panel. I removed the housing and looked around where the oven control knob goes in, this is what I saw. (Here's a link to take a look.)

http://www.appliancepartspros.com/part_details.aspx?part_id=2632838&pn_=WB27T10006

The part number is #WB27T10006, I believe. Nowhere in any of my two pieces of paper here (Owner's Manual or the Maintenance Schematic that was found inside the bottom utility stove) did it mention anything about a possible adjustment to the 'PREHEAT' signal. I assume that's all in this one condensed part. The part number mentioned here were printed on that Maintenance Schematic and read: For Kenmore® Electric Self-Cleaning Free-Standing Range with the Model Numbers #935.XXXXX.

The price is $90.78...something that I'll have to personally consider if I really have a need to replace it when the oven, in all actuality, is heating and maintaining the proper selected temperature. It's kind of foolish to replace it only for this early 'preheat signal' error.

Thanks for all your help throughout this. I guess at this point I will leave well enough alone.

Sincerely,

You can not go by looks a lot of electronic controls look the same.

** The part number is WB27T10006. The part number mentioned here were printed on that Maintenance Schematic **

Than I would have to assume it is correct.

** Nowhere did it mention anything about a possible adjustment to the 'PREHEAT' signal. **

Such things are not normally adjustable in the field (ie. outside of the manufacturing plant), no.

** The price is $90.78 **

It's a little cheaper here:

proably but you might want to keep an eye on it as it may be a sign of things to come?

Good luck!
