SOLUTION: Dispose of the old ice cubes down the sink and let the ice maker make new cubes.

3. PROBABLE CAUSE: Old and unwrapped frozen food stored in the freezer.
SOLUTION: Throw away any frozen food that is not properly wrapped or sealed as this can cause smelly ice.

4. PROBABLE CAUSE: Mildew has entered the freezer area and contaminated the ice cubes.
SOLUTION: Vigorously scrub and clean the inside of your freezer and ice maker tray. Use a pail of warm water with some baking soda sprinkled in. Wipe it down using a sponge and be sure to remove all signs of mildew. Throw away any food if necessary. You can also use a Ice and Freezer Deodorizer to assist you after you are finished cleaning.

5. PROBABLE CAUSE: Bad water supply. Water supply has become temporarily or permanently contaminated.
SOLUTION: Turn off the water behind the refrigerator and remove the water line that goes from the wall to the filter. Slowly turn the water on from the valve on the wall and let the water run into a bucket. Check to see if the water is clean and clear. You may have had a bad water supply temporarily such as the city doing work on the supply pipes or similar. If the water was contaminated, then you will need to replace the water filter and flush out the ice maker water lines.

  1. We have a copper line and a filter which tells us when it is time to change (every six months) and our ice maker still has a horrendous smell. What’s the next step aside from getting a new fridge?

  2. why didn’t Whirlpool put cooper tubing instead of putting plastic knowing it will cause health issue. Sounds to me like a recall?????

  3. Do I have to replace the whole system if my ice maker doesn’t have a water filter? My fridge is: Model No. PLHT219TCK5

  4. The musty ice comes from the new flexible lines used to attach to the ice/water. They are usually flexible stainless (woven in appearance). These lines are lined with rubber. The rubber holds the bad odor and taste. Change the line to PVC or copper. Problem solved! I tried ALL other suggestions, even spending over $100 in new filters, until a fellow at Lowe’s told me this fix. He said they have numerous complaints about this since plumbers stopped using copper.

    Trust me, this is the problem.

    1. Thanks for the GREAT information.
      Just put a new SUB ZERO in and installed one of those flexible stainless lines.
      Never had the problem before.
      After a few weeks started to get bad Odor and taste.
      Tried everything and nothing worked.
      I read your post and changed to copper and it corrected problem.
