Stove doesn't heat up during hot days

Hello,
Wife does crazy over it so I just want to understand if it is normal or not.
We noticed that during hot times - outside temp is over 85 - we cannot use our electric stove because it doesn't want to heat up. It is OK next morning...
Is that normal? Can I contact our electric company to fix the issue? Is there a fix? What should I do?
Thanks much for the attention.
Alex.

 

Obviously that is not normal. Is your stove electric or gas? Do any other 240 volt appliances/machines (air conditioner, electric dryer, well pump...) stop working at the same time? Does anything on your stove work when the elements do not heat?

Your power company is only responsible for getting the power the meter on your house. You are responsible for everything after that. If your other 240 volt appliances work properly that means the power is getting to your house and the problem might be isolated to your stove circuit. If your other 240 volt appliances don't work it could be a power company issue but it could also be a loose connection in your house's wiring, probably at the panel or meter base.

 

Thank you!
The stove is eclectic. Top heaters work all the time.
The issue is highly reproducible. For instance, the stove was not working yesterday evening and it was working today's morning. I don't think that loose wire can be attributed to the issue
The only other 240V appliances are washer and dryer, it looks like they work fine.
My theory is during peak hours (evening) when a lot of people and businesses use AC the voltage in the grid goes below 110V and stove cannot work on that lower voltage. During hours when the volage is more or less normal the stove works.
Is that possible?
Maybe I need to ask to give me 200A at main?

 

Please post the brand and model number of your stove.

Do you own a multi meter so you can check/monitor the voltage in the home?

Have you noticed any other unusual electrical phenomena? Do the lights in the house dim or get brighter when the oven is turned on and off?

Resistance heating elements (stove top burners, oven elements, toasters...) don't really care about voltage and will operate over a wide range of voltages. Depending on your stove the controls might be sensitive to incoming voltage fluctuations, that's where your stove information comes in.

 

This is Whirlpool model WFE515S0EW2
Multimeter is a very good idea, thank you.
So far we did not noticed anything else.

 

So you are saying that the top elements always work..... correct ?

That would mean the oven has the problem.
Is that correct ?

Does the control panel respond normally where it looks like the oven should be heating or is the control panel not functioning for the oven ?

 

Everything - controls (control panel) and top heaters work as expected all the time. Except the oven doesn't heat when the temperature outside is above 85.
No errors are shown ever.

 

I need to understand 100%.....
So you set the temperature on the oven.... it goes into heating but doesn't heat.
Does your display normally show pre-heat until it's up to temperature ?
Have you tried broil ?

For the most part.... the controller is not voltage dependent. It has a switching power supply that runs on a wide voltage swing. The power supply is 120v and connected to neutral and L2/R leg.

I would recommend checking the 240v in your home and check from each leg to neutral/ground.
Establish a baseline. Then check it again when the oven won't work.

I set the temperature on the oven. The count starts from 100. And it stays at 100 for an hour or longer. The rest looks normal. And of course, the oven is cold inside. I don't remember if the oven shows *preheat*, we used to monitor the rising temperature. The oven beeps when the temperature reaches set value.
We are not big fans of broil, we tried it once. It looked like the broil was not working - the oven was cold inside. Then in a couple of days we tried the broil again and the oven was heating up. At this moment we have not tried since.
Thanks a lot for the PDF.
Thanks a lot for your time and efforts! I really appreciate it.
