Product review (5 stars): Works for RV refrigerator  Norcold model: 928
This unit was an exact replacement for the ice maker that developed problems in our motorhome.
Norcold refrigerator Model # 928 i M  (i M for ice maker)

I searched the forums for advice and ended up removing the ice maker and taking it to Lowe's.  By opening boxes and comparing, this one looked identical and had the exact mounting configuration.  I installed it and waited over night and had ice. It seems to be working properly.  The old one had begun making major icicles due to an internal leak in the control module.

I expect that this ice maker was commonly used in RVs, especially in the Norcold brand refrigerators. It came with a water valve.  I did not replace the existing valve, so I now have a spare.

I paid 99.88 plus tax which is a little more than Amazon's price, but I could not risk ordering one without knowing for sure it would mount properly.
