Fridge fan quieting

I had a side by side Dometic that had fans inside and out. One of the inside fans was getting quite noisy. To replace it was a big job and the ice maker was acting up so it got retired at 9 yrs old. So if it is an inside fan you may need to replace the fan.

My fridge fan is louder and whinier inside the trailer than outside.
There are 4 fans, fridge is in a slide, so side vented.
Anybody done a mod to reduce the sound?

If you wire two of those fans in series, you will cut the fan speed in half and reduce some of the noise.

All 4 fans are outside. There is no inside fan. That is what is confusing me.
This is a new trailer...
Will check into Richards suggestion

thx

It might help if you post what brand it is. Is it obnoxiously loud or you're just not used to the sound? I believe some have replaced the fan(s) with a quieter ball bearing type.

We have a Norcold fridge in our slide and I have never heard the fan(s) running, even close up outside. I do hear the burner when running on propane tho.

The fan on our new Norcold must be thermostatically controlled, it runs only in hot weather. Side vented in the slide.

For the OP, I'd look for new replacement fans with ball bearings.

It is loud enough that you can hear it while watching TV movie with volume up.
Not getting used to it after 3 months almost full time. It is a new trailer so trying to make it a warranty issue, but early indications are not positive.

Just buy a better 12v fan from amazon and replace it. The factor fan is the cheapest thing possible.

For fridges mounted in slides, I have wondered if using a 10~14" electric radiator fan mounted on one (or both) of the outside covers would work well. You could even use a speed controller so it doesn't have to turn faster than needed to reduce noise. They're cheap and flow a ton of air.

If there are any gaps around the refer the noise can easily get inside and with four of them it is probably like big speakers in a speaker enclosure.

Remove the moulding around the front of the refer and seal around it. Noise can come through the smallest holes.

This a good idea, something to look into. My fridge is slide mounted with two fans. I hear them if all else is quiet but I wouldn't classify them as loud.
