Whistling noise when cooling on Kenmore built in oven model #790.48783900

Bought in April 2010 on sale, installed in June 2010. Replaced cooling fan in November of 2010 (under warranty) Cooling fan is again making a whistling noise when heating up and cooling off. Sounds like a police car in the distance. What are my options? How long will it last when it starts to whistle? Why is it whistling?

    Is this cooling fan a defective product? (2 in 1 year) or is this oven have a known issue that should be fixed by the manufacturer? Is this something I can replace myself rather than paying $75 for Sears to come out plus the cost of the repair?

    Troubleshooting is not an issue here...I know it is the cooling fan since this is the exact same thing Sears replace (under warranty) a year before. Is this something i can do myself? I know I will have to take the oven out to get to it.

These types of ovens are complex to troubleshoot and repair. I would contact an appliance tech.

SOURCE: Display reads U60 Cooling Fan - oven won't heat

The code is telling you that the oven has sensed a fault in the coling fan circuit of the upper oven. Dacor has had a few problems with the cooling fans in these new ovens since theyve been out, so most likely you will have a bad fan motor. If that is the case, be prepared to have the repair person have to pull the oven out of the wall to get to it and change it. If its a realy board problem (less likely) than that can be changed from the front. Call up Dacor and find an authorized servicer in your area since it will still be under warranty. Good Luck!

SOURCE: zanuisi top oven making noise

Yes , there is a cooling fan located at the top of the oven
It could be the fan blades catching, or a noisy fan bearing.
You would have to access it by removing the top oven cover to check., and yes it could be as a result of having it cleaned.
Plz rate my solution.
Thanks.

SOURCE: cooling and/or convection fan

I had the same problem. The screen protecting the fan bends into the fan from the heat. Take off the top front control panel (3 screws), reach in to the back where the fan is and push the screen back away from the fan. As always, turn the power off first to avoid shock. This should solve your noise problem.

SOURCE: Delonghi ESM465ST Oven Noisy Fan

If it is a fan assisted oven, then you are likely to have 2 fans, an external cooling fan, and a fan inside the oven for ciculating the hot air.
So to answer your query, yes it is a noisy fan you are going to have to establish which fan.
It could be a worn bearing, or the fan blade has come loose.
If it is a worn bearing, thge only cure is a new fan.
Hope this helps with your problem.

Testimonial: "Thank you for that. It's noisy even when the fan inside the oven isn't running (ie, just on convection) so guess that means it's the external fan?"

SOURCE: My AEG competence oven is

I would suspect that the problem is caused by the external cooling fan located under the outside cooker cabinet housing, which continues to operate as the oven is cooling down if it is built in, you will have to remove it from the oven housing to access the fan

My oven makes a huge whirring buzzing noise after 20/30 minutes of use. I replaced the cooling fan motor but that has not helped. Surely this is not normal?

It sounds like you're experiencing an issue with your SMEG DS96MFA7 oven where a noise occurs after some time of operation and continues even after the oven is turned off. Since you've already replaced the cooling fan and the noise persists, there are a few possibilities to consider:
  1. Heating Element: The heating element in your oven might be expanding and contracting as it heats up and cools down during operation. This can sometimes create noises, especially if the element has developed some internal damage.
  2. Cooling Fan Motor: While you've replaced the cooling fan, it's possible that the noise is coming from a different part of the fan assembly or from the fan motor itself. The noise might be due to vibrations, a misaligned part, or a problem with the motor bearings.
  3. Exhaust Fan or Circulation Fan: Some ovens have additional fans for exhaust or circulation purposes. If your oven has these fans, they might be causing the noise. Check if there are any additional fans present and inspect them for any issues.
  4. Expansion and Contraction: As the oven heats up during use and then cools down after being turned off, various components inside the oven can expand and contract. This can sometimes result in creaking or popping noises. This could include metal components, panels, or other parts.
  5. Loose or Vibrating Components: Check for any loose or vibrating components within the oven. Even a small loose panel or part can generate a significant amount of noise, especially as it vibrates against other surfaces.
  6. Gas Ignition System: If your oven uses gas, the ignition system could be causing clicking or ticking noises as it ignites and heats up.
  7. Electrical Components: Certain electrical components, such as relays or transformers, could also be causing the noise if they are malfunctioning or vibrating excessively.
Since diagnosing the exact source of the noise can be challenging, especially without being able to inspect the oven in person, I recommend the following steps:
  1. Carefully Inspect: When the noise occurs, try to pinpoint its source by listening closely and observing the oven's components. This might give you a better idea of where the noise is coming from.
  2. Contact Professional Help: If the noise persists and is affecting the functionality of the oven, it's advisable to contact a professional appliance repair technician. They have the expertise and tools to diagnose and fix the issue accurately.

Ykemc308kmo oven fan noise

You are probably correct the cooling fan can wear out. You will have to order it by model number. They are a bit tricky to install depending on the oven, but not hard once you get to the fan area. Somke are behing the cabinet and you will have to puul the oven out and some are in the control panel area.

Noise but not fan

There is another fan motor built into the top of the oven, this is the cooling fan, so that is what you can probably hear.
To access it, you will have to remove the top cover, and possibly the rear external panel as well.

Oven makes a noise when I turn it on.

If it is a fan assisted oven , then it sounds like a noisy oven fan.
It could be a worn or dry bearing in the fan motor. if you open the oven door , you should be able to tell if it is the fan by listening to it carefully.
The other possibility is if it has a cooling fan in the back or on the top of the oven, it could also be that causing the prob, these are about the only things that could be making a noise, as there are no other moving parts that could make a noise.
PLz rate my solution.

Thanks.

De Dietrich oven not working!

I suspect that it is the oven lock that needs replacing. I bought a De Deitrich oven (pyroclean) in Sept 2007. The oven failed to heat in Aug 2009. The oven lock needed replacing which meant the unit had to be removed from the wall. It was replaced under guarantee but failed again in June 2010 and was replaced at a cost of €140 by enginneer. I am very dissappoined in the oven and expected to have no problems with it considering the DeDeitrich name. I would not recommend it to a friend. By the way the clock is easy to use if you follow the instructions exactly. Oven used by two careful owners only.
