Does your Kegerator go Bump in the Night? Here’s how to fix that.

Mine did.  I have had a used Beverage-Air BKV DD68 two door kegerator for about two years and it has performed admirably so far.  About a month ago every-time it kicked on it started to sound more and more like a Mack truck diesel engine in my brewery.  The kegerator was noisy and getting louder by the day.

I opened the front panel to see what the ruckus was all about but couldn’t find anything.  I placed some rubber washers under the entire compressor-fan-radiator assembly to hopefully dampen a vibration but to no avail.

At this point I didn’t know what to do, it was getting louder, though the fan was still moving.  I couldn’t get to the ‘guts’.  I was about to take off the entire left-side panel until I figured out that you can just ‘pull’ the entire compressor-fan-radiator assembly out.  It’s mounted on a skid that you just pull out.  You don’t have to worry about bending or crimping freon lines as they are coiled to allow it to stretch to come out…ingenious.

Now, pull it out all the way…don’t be shy.  Just make sure the fan is ‘off’ at the time or better yet, that the unit is unplugged.

I listened.  I poked things while I listened.  I felt.  I tried to feel where the noise/vibration was coming from.  There were no freon lines rattling.  The compressor mounts were still rubbery and flexible…the compressor was silent and vibration-free while on.  The radiator assembly was solid.  All screws and bolts were tight.  That just left the fan.  The fan turned easily when off and didn’t have a ‘tick’ to it.  But it did have a serious vibration and the noise seemed to come from it.

I went to Beverage-Air and learned that you can only get parts from a local distributor.   I then found CPS Ohio and gave them a call to get a replacement compressor fan.  Luckily they had it in stock and I had it two days later!  Just in a nick of time…even though my wife has warmed up to having the kegerator so she can use it as an overflow refrigerator, the noise was getting that bad.

Now the hard part.  My fermentors were full, the ones right next to the kegerator.  I didn’t have enough room to pull the kegerator out.  And I couldn’t reach back to unplug it. So I had to get McGyver on it and do it between it kicking on and off – about 5-10 minutes. (Not recommended, please unplug your unit before any work).

So as soon as the compressor kicked off to cycle, I first disconnected the fans electrical leads from behind the compressor.

The fan leads are red clips.  COOL!  I thought I was going to have to cut wires and solder.  Beverage-Air, you think of everything!

The two red clips are the fan leads...just pull them off.

Now with the fan unplugged, I went about unscrewing the 4 hex-nut screws on the fan mount.

Once those four screws were removed there were four smaller hex nut bolts holding the fan to the fan mount (not shown).  This takes about two minutes.  Time’s ticking….

Once the fan is removed, you have to remove the fan blades from the motor.  It unscrews with an odd-type ‘nut’.

I realize that my time was ticking away figuring out how to get the fan off of the motor.  I went to my son’s room to get a big fan to put in front of the radiator in case it cycled on.  It did.  The last think I needed was to burn the compressor out due to lack of cooling.

I then put the fan on the motor and the motor on the mount and the mount on the skid.  I fished the fan wire leads back under the compressor.  With the compressor on, the freon lines got real hot, real fast.  I plugged the fan leads in and….voila!  The fan is on and it’s SILENT.  Nice.  I replaced the housing over the electrical box, made sure that all the screws were tightened then I pushed it back in.

All done!
All done!

Three hours later it’s been silent-as-a-mouse.  And with the rising heat this summer, just in a nick of time.

Thanks Beverage-Air for the great engineering and thanks CPS Ohio for the quick service.

  1. How loud is loud? We just got a bev air dd58 and it is pretty loud when the compressor comes on. It is in our dining room that is open to the living room and wondering if we need to give up on our idea of turning our dining room into a pub due to how loud the bev air is. It is brand new but I’m wondering if the fan is bad or it just is too loud for home use.

  2. You do notice it when the compressor is on…I don’t think it should be loud – just noticeable. The fans run all the time inside so you will always hear a hum when the compressor is not on.
