Sulfer smell in Freezer

[WeBeGone2]

I have a 4 door Norcold 1200 fridge/freezer. The compartment that houses the ice maker smells like sulfer. The other freezer comparment does not smell. Neither does the fridge part. I thought I had bad/old water in the lines. I drained the tank, refilled it ran the ice maker dumped the ice about six times. Still there. I dumped the onboard water, added bleach and ran it through the system til no bleach smell. Two years ago the cheap ice maker line began leaking so I replaced it with a heavy duty one. Even the ice cubes smell. In the past I used the M/H at least once per month. Typically I would shut down the fridge during this down time. I now am now a fulltimer. Just two days ago I defrosted the freezer. Dumped all the old ice and started over. Still smells.
Anyone got a good guess as to what is going one?
It makes my bourbon and coke less tasty. We can't have that now can we!

Did you have the odor with your old icemaker?? Did it start after you installed the new HD unit? If so, I would suspect there's some material in the new unit causing your odor, just a thought. Just this month I replaced the icemaker in our Norcold 1200LRIM with a whirlpool unit I bought at Lowe's, tested it out works ok, no odor.

Did you let the bleach water run to the ice maker?

As for the smell, I'd try to clean with good soapy, warm water, rinse really well, then sprinkle baking soda and let it sit for a day. Repeat.

Do you have a water filter inline with the ice maker? It may also feed a water dispenser at the kitchen sink. I would recommend you change it or install one if you do not have one. You may have be connected to a water source that had mineral deposits and it has stuck to the ice maker mold. Every time the ice maker goes through a harvest, it has to heat the mold to free the ice. This may be where the odor is coming from.
There are a couple of ways to deal with it. I would recommend you remove the ice maker and use some calcium, lime and rust remover type of product to clean up the mold. But with it out you can use your own judgement and also you can better rinse it before putting it back into operation.
Since you are full timing. I would recommend you also invest and use a whole house water softener to help with this and other kinds of problems, imperfect water can do to a coach.
