Crusader 290RLT Fridge Fan Noise
Hi,
I'm starting a new thread on the 290rlt fridge fan noise because the original one started by Jim Hawthorne on 5/1/2012 is no longer active and I have a question.
I am starting my first summer with my 290RLT and experiencing the same loud refrig fan noise. The fan I found on OutletPC has the following specs and wanted to know if this is the same fan that Jim installed. The CFM is around 32 which seems low compared to some of the Sunon's. The fan speed seems lower also so I'm not sure if this is the same fan Jim installed.
I'm hoping Jim is still on this forum and could respond to this post.
Thank you

We noticed on our weekend maiden voyage that the fan on our 295RST is also noisy. Where is the original thread?

290rlt Fan noise
At the top of the Forum page is a "Search" box. Type in 290RLT and then click on search. When I do that, the original thread is the first one listed.

I hadn't noticed the fan being overly noisy in our 2014 295RST. Maybe they switched fans?
I will listen for it this weekend though.
Then again our first 2 weekends out it has been at or near the freezing mark.

It generally doesn't come on until the outside temp is ~80 or above.

So there is a thermal sensor to enable the fans?
If so then it might be a while before I need em given the way the weather has been around these parts.

Yes, it's normal to have fans to pull air thru the condenser if your fridge is in a slide out. This is how Dometic wants them installed.

Hi! This is Jim!
Please note that the 2 fans I installed were the "Silent 9 TC" version; these move about 38 CFM each. The "TC" stands for "Thermal Control" and makes the fan run between 900-2000 rpm, depending on the temperature inside the enclosure. The basic "Silent 9" runs at 1500 rpm and moves about 32 CFM, so I recommend the "TC" version.
My original Sunon moved about 70 CFM, and the 2 Silent 9TC versions together move about 80 CFM. The actual volume of the enclosure behind the fridge is approximately 6 cubic feet, so I feel there is more than sufficient air exchange.
I chose GELID fans as I found that they always ran flawlessly while cooling computer cases, router arrays and server racks, and never had a failure. But there are other manufacturers that also make quiet fans.
I have had no problems with the fans and really appreciate the quiet!
If you can wriggle a camera down into the enclosure and get a photo of the existing noisy fan, you can then go get the specs on it before you buy a replacement to make sure the replacement(s) will move enough air!
Good luck!

Here are 2 pics of the installation: The original single Sunon and the 2 GELID replacements... Note the thermal sensors 'pig-tailed' just below the cooling fins...

fan noise
Thanks for the PM Jim, I do have one question. i have a 325RES with the frig, in the slide and noisy fan. Question is my fan is about 12-15 inches down inside the top opening. was yours? If it was did you put the other two in same spot or move them. I just think it will be hard to put the replacements down there with only a small opening. Thanks Ron

Yes, Ron; mine was down about a foot also. The material that acts as a cowl to route the airflow up over the cooling fins was just 1/8" plywood, and I cut it off with just a box-cutter so I could get at the old fan. After taking out the old fan and replacing it with the 2 new GEHID Quiet 9TC fans, I just glued and stapled the 1/8" plywood piece I had cut out to a 1/2" square piece of wood and screwed it back into place.
Here are some photos... The old fan before removal; the new fans; the completed job...

Thanks for the post Jim......My 290rlt also has the 2852 frig like yours. I have not started to install new fans yet but I noticed the schematic for my frig shows one fan with one red and one black wire. The new Gelig fan appears to have three wires. What did you do with the third wire and what color is the third wire? Did you just cut it off and not use it?
Thanks
Dale

Dale, you can just cut off the yellow wire. (at least, most are yellow) In a computer application, the yellow wire simply sends current back to the computer's CPU, which the CPU then interprets as the fans RPM (tach speed). Just wire in the red and blacks in parallel.
Most DC fans just have 2 or 3 wires, but some computer/server fans have a 4th grounding wire. If anyone comes across a 4 wire computer fan, check and make sure it's a DC fan and not an AC fan, as some 4 wire fans are AC! Also, some larger 4 wire computer fans have a surprisingly high amperage draw!

Fan replacement
Hi Jim,
Thanks for all the good info you have provided.
I was able to look at my existing refrig fan today. It is a AD0912UB-A71 made by ADDA. The best I can tell from the internet is this is a 3300RPM fan with a 60CFM air flow. The new Gelid Silent 9 TC fan runs at a max of 2000RPM and the air flow looks to be 37.89CFM. I currently have only one fan installed but there is a second set of holes for installing another fan. Do you think 2 of the Gelid Silent 9 TC fans are an adequate replacement for the one ADDA fan I currently have?
I am really anxious to replace that existing fan cause the noise is driving me crazy. When it comes on, I need to up the volume of the TV to drown it out. My wife doesn't even notice the refrig fan so she thinks I'm nuts.
Thanks
Dale

Dale, truth be told, ALL our wives think we're ALL at least a little bit nuts!
I replaced the noisy old fan with the 2 new ones a year ago last spring, and they have been working fine ever since. Even in the heat during two summers with the fans running at max RPM, they are almost inaudible. When we were in Canada last year, my daughter and son-in-law joined us in the Rockies and slept on the air-bed next to the fridge and didn't notice any fridge noise at all. The original fan was very noisy even up in the bedroom and was as annoying as an invasion of mosquitoes. (it was so bad that on the first trip out, we shut the fridge off at night!)
So in my opinion, yes; the twin fans move enough air, and it seems to me that the fridge cools down faster than it did with the original fan. (Of course, that could also be due to the fact that the 1/8 plywood 'cowl' is now 1/2" closer to the fins, and therefor is directing more of the airflow directly over them???)

We had the same problem with our 290 last year when we bought it. My neighbor is an electrical engineer and happened to have some great replacement fans. They are ball bearing, higher cfm and lower power usage. Rather than taking the old ones out we fabricated a metal strip to hold the fans and attached the strip to the wood wall in back of the fridge. Snipped the old wire to the old fans and wired the new ones in. Works like a champ and are much quieter. I'm on the road right now but I can either find the specs on the fan or you can find a quieter one locally. I believe he has more at home and may be willing to part with some if there is an interest. Feel free to drop me an email at pryner@verizon.net if you would like more information.

Frig Fan replacement
Jim,
Today, I finally got around to installing the 2 new Gelid fans bought several months ago. Just before the really hot weather gets here.
In this post last year you made the following statement:
"Of course, that could also be due to the fact that the 1/8 plywood 'cowl' is now 1/2" closer to the fins, and therefore is directing more of the airflow directly over them???"
Could you clarify what you mean by the "cowl" is now 1/2" closer to the fins?
Does it mean the top of cowl is now 1/2" higher than it was before so the open space at the top is 1/2" smaller. Or do you mean the cowl is 1/2" closer to the back of the frig? My fans are up against and touching the cowl so there is no way it can be moved closer to the back of the frig. But I could install the cowl so it extends up higher by another 1/2".
Thanks for your help
Dale

If I understand Claude he means that he was told the noise is normal. If that is what he was told, then I believe it is normal because I see many posts on other forums about the noise regardless of who the rig manufacturer is. Sorry if I misunderstand.

Hi, Dale! Sorry to take so long to reply. Just back from AZ, NM, + TX...
A better photo might have helped????
By "cowl" I meant the piece of 1/8 ply that I had to cut out to get down into the cavity behind the fridge was about 6"X12" so when I put it back in, I glued and stapled to the 1/2x1/2 piece of wood you can just see at the bottom of the photo.
To attach that piece of 1/2"x1/2" piece required me pushing the existing 1/8 piece of plywood away from the side of the trailer. That moved the thin 1/8 plywood closer to the fins.
Am I making any sense here??? Let me know!
Jim
Hope this message gets through to you!
Jim
