FIXED C2S950P4M1W2 Noisy fan on GE Cafe range -- normal?

I have a relatively new GE Cafe Dual-fuel slide-in range (Model C2S950P4M1W2) that I installed during our recent kitchen remodel. After a few weeks, the oven started randomly shutting off during preheat. (Reading a few posts below, sounds like a not uncommon issue.) GE Service came out, diagnosed it as a faulty vent fan, and replaced the fan. However, the new fan is excessively loud. It sounds like a hair dryer. The tech said "that's normal." In disbelief, I called GE and scheduled another service appointment to have another tech verify this. He came out today, listened to the fan and also said it seems normal, but still ordered a yet another fan to be replaced next week.

So my question is if it is normal for the oven vent fan to be ridiculously loud? The previous fan was not anywhere near this loud (but also ended up being faulty). But before we were having the shut-off issue, it worked fine for a few weeks. We could hear it turn on, but was never intrusive. Now, we can't even stand to be in the kitchen when the fan is running. When the oven cools down enough that the fan finally shuts off, the "silence" is deafening!

I have a hard time believing that GE would design a higher-end range with such a noisy fan. Can anyone confirm if this seems normal? If it is, are there any tricks or hacks that I can do to make it run more quietly? If we can't get around this, I hate to say we might need to look for a new range, since the matte white Cafe coordinates with everything else we've done to the kitchen. (We also got a matching Cafe refrigerator.)

Any input/insight appreciated.

Possible it is related to this service bulletin that pops up for that model. Maybe was not installed correctly.

Here's that blower motor that's in the service bulletin:
GE changed the part number WB26X29060 to part number WB26X32571

Ok thanks. Maybe I'll try to remove and reinstall the fan to see if that makes any difference. I also still have the original fan, so I might switch over the circuit board from the new fan to see if that also changes anything.

I've done a bit more googling and there are a few other complaints about the fan noise floating around in reviews of this range... I honestly can't believe that people would not complain more about this. It ruins the user experience.

Nope. I think it was simply designed that way. I replaced the fan with the second replacement fan (so the third fan in total) and it was still noisy. I even swapped the circuit board from the replacement fan and reinstalled the original fan with new circuit board and it was still noisy. It almost seems like it "ramps up" and gets noisier as the oven gets hotter. Once we're done cooking and the oven is shut off, we open the oven door to get it to cool down faster so thermostat will shut off the fan sooner. It really is a shame since it's a great looking range; it's just ridiculous that they couldn't design a fan that would run more quietly. Something to keep in mind if we ever replace our appliances again.

Hi, our cooling fan noise problem was resolved. The fan sound is now what would be acceptable for low speed! Really fine now. The technicians that replaced the original blower in January connected the red (high speed) and black (low speed) wires to the wrong tabs on the blower. The technician who came out last week installed a new blower and connect the red and black wires to the opposite clips than what the technicians did in January.

Look at the side view photo in step #5 in August 2018 GE Training Bulletin TB17 18. Notice in picture the red wire connected to the tab closest to you. GE could do better to provide instructions and clip design or color coding on the tabs to ensure the red and white wires are clipped onto the correct tabs.

Interesting... So are you saying the picture in the training bulletin is correct? So my wiring should match the picture? Or the picture is incorrect?

AHA! That was exactly my problem! This morning I finally got around to pulling out my range and taking off the top and found exactly what you described: The H and L wires connected to the fan were reversed from the picture in the technical bulletin. So I switched them around, reassembled and turned on the oven. Once the fan started up I could barely hear it.

As I described in my original post, when we first got this range last summer we used it for about two weeks before it started having the issue of shutting down during preheat. So GE service came out to replace the fan. However, I remembered that the original fan was significantly quieter for the short period we used it. I actually had GE service come out two more times to replace the fan again and then with a different technician to verify the fan was supposed to be that noisy. BOTH confirmed "yes, that's normal." I couldn't believe it, but accepted it. But I still felt there was no way GE would design a high-end range with a fan this loud. Both of those technicians should be ashamed of themselves.

Then last week I ran the self-cleaning cycle on the oven, and immediately noticed that the fan was WAY quieter during the cleaning cycle. This is what made me realize that this could possibly be my problem, and it makes sense: During the self-cleaning cycle, the oven heats up to an excessively high temperature, during which time the fan should probably run at high speed. But during normal cooking, it should run at low speed. Mine did exactly the opposite.

Thank you for posting this! To think that I would have lived with this ridiculously loud fan every time I cooked for the next however many years.

That is so great!!! I wish GE provided better installation instructions with the replacement fan! I am sooo happy that I resolved it just before everything ramped up and we started our stay at home! Yes now baking in the morning is nicer with a quiet fan.

Just adding more information for the future.
4.
B R
w
Six pin connector
Reactivate the cooling blower in the Service Mode and check for 120 volts AC to the low speed tab (black wire) and the neutral tab (white wire) of the blower motor (see strip circuit below). Check for good connection and voltage at door lock motor switch and J903 pin 1 on RC17 machine board on rear of unit. If 120 volts is not present from J903 pin 1 to neutral when cooling fan is on in service mode, replace the machine board.

Disconnect power and check for resistance between white to red (~ 31 ohms) and white to black (~ 47 ohms) on the blower motor.

If all wiring checks are correct and the blower wheel rotates freely, replace the blower motor assembly (BLOWER TANGENTIAL - WB26X29060(GE changed the part number WB26X29060 to part number WB26X32571)) by removing the four hex-head screws that attach the assembly to the blower shroud.

The upper back wire cover and the right side panel will have to loosened to remove and replace the blower assembly. Bulletin RA02-18 Below!

Hey y'all, just registered to say thank you all so much for this — we purchased a scratch-and-dent GE Café C2S900P2MS1 and were fairly pleased with performance the first night after installation: baked some pizza, etc... But the cooling fan was kinda noisy? Next morning we go to bake scones and ... disaster. It wouldn't preheat, started resetting itself every few seconds to minutes past 250 °F, we finally got the scones baked but only by standing in front of the thing and starting it up again after each reset.

Anyhoo... found this post, read the service bulletin, took the top off, found the blower motor... the wires weren't reversed as it happens, BUT...

The wires for the RJ 45 port (circled; this port is for diagnostics? I presume?) were stuck over towards where the arrow is pointing and were rubbing against the blower motor's rotor, causing the rattling and juuuust enough disturbance to cause the resetting, apparently.

Hopefully it'll stay that way and we'll get many years of service out of the thing, but... wow, that's a bit finicky. 😂

Cheers!
