Frequently Asked Questions About Domestic Refrigerator Repair:

Check to see if there is an inline filter somewhere along the supply line. If she bought the refrigerator new or relatively new, most modern ones have the filter mounted inside or at the back. The owner’s manual will indicate the location if present.

Other than that though, these "partially working" problems are really hard to trace even when I'm right there in your kitchen! There is nothing except a clogged filter that you've told me that rings a bell, like makes me want to say..... "well sure try this.." as in many other problems. Your daughter may have to call someone in on this one. Sorry I could not be of more help,
