loud refrigerator

We just purchased a Grand Design Imagine 2150RB. We love the layout and etc. but we do have one issue. The fridge is loud. I think it has something to do with the cooling of the motor that makes the noise? It will cycle on for about 20 minutes to half an hour then stop for a while. You can definitely hear it outside of the trailer and inside. Does anyone else have this problem?
  • If it isn't, it's the auxilaey cooling fans. If it is a conventional compressor fridge, the compressor mount is faulty.
  • A common complaint of floor plans with the frig in a slideout. You are hearing the cooling fans.
    They need extra cooling fans to move the air because there is no vent through the roof....like most RV friges.

    I have read that some replace the cooling fans with much quieter computer pancake fans....Might want to explore that option.

    Actually that is EXACTLY what I did with mine. 2 Fluid Dynamic Bearing CPU fans from Flea-Bay for 30 bucks. Problem solved, no noise whatsoever.

    SidecarFlip, could you post a link to the fans you purchased? My Dometic is in a slide and the fans run on/off constantly. A description of your replacement would be wonderful! Thanks.

    Thank you!


    Good idea ScF ,

    It may or may not apply to the OP but ...
    if you have a Dometic, there are many threads on that fridge making loud fan noise. RV.net, Heartland and Forest River owners forums.

    If need links i have.
  • Easiest way is to peruse E-bay for 'Muffin Fans' and order one or two, probably 2 as multiple fans move more air. You want 120mm case fans, Fluid Dynamic Bearing, which are silent. Be sure to buy a 2 WIRE LEAD FAN(S). The 3 wire fans are speed controlled by a CPU. You want 2 wire only.

    You remove the existing fan or fans and install the new fan or fans in the place where the old fan(s) were, wire them both together and extend the positive and negative wires to the existing positive and negative wires (that powered the existing fan). Mounting the fans will be the same as the existing mounting because all the fans (yours now and the new ones have the same mounting holes).

    Your existing fan is controlled by a snap disc thermostat affixed to an outboard fin on the upper condenser and it will run your new fans just fine.

    The fans will come with a small plug attached, you cut that off and attach the bared wires together between the fans and to the existing positive and negative wires.

    All there is to it.

    The OEM uses the cheapest fans you can get which are sleeve bearing and they make noise. The FDB fans have floating, non contact bearings and are silent (other than some very low noise from the air moving through the blades).

    Real straight forward and there are literally hundreds to choose from on Flea Bay so you pick what you want and install them.

    120mm FDB case fans is the key.
