Ed,
It definitely sounds like a problem with the fill setting on your ice maker. If you have a Norcold 4-door, I KNOW that it's adjustable, as I just adjusted mine yesterday. Was having a problem with the ice cubes coming out as one solid block of 8... and several times heard the ejector bars straining, struggling, groaning trying to get the ice cubes out.
There's a really good service manual for the Norcold Ice Maker on the Bryant RV site. It's a PDF document (5.5MB... so be sure you aren't on a bandwidth-restricted connection) you can
download here. The water fill adjustment instructions are on page 62.
I think the ice makers in all of the refrigerators are the same... so even if you don't have a Norcold, these instructions may apply. If not, check out the listing of available service manuals at
Bryant RV's site and see if they have one for your fridge.
Sounds like an adjustment should work for you.
