Just an update: our contractor arranged for a KA certified repairman to come today. As you all suspected, it was a clogged drain line. The repair guy said it was better to remove the gasket rather than notch it - he said it's a tight space and is near the compressor, so it tends to get plugged up from the heat and pressure. He said he's done this at least 100 times, on all models of bottom freezer refrigerators. My contractor was very anxious to confirm it wasn't his fault. This all began after they installed the water line, so I was afraid there had been some mistake. It probably wasn't totally unrelated, since they kept the fridge in the kitchen throughout the demo but unplugged it repeatedly to move itmultiple times, frame it, and also to do a heavy up at the outset of the project. But it wasn't their error, clearly. This being a high cost area, I paid $145 for the fix, but truthfully I'm glad it wasn't more! (not long ago a clogged washer drain wound up costing $1k just for the plumber - I'm pretty sure we were fleeced on that one!) Thanks so much to all of you for pointing me in the right direction!

oops! meant to post this in "flooring"... sorry!

Thanks, our line to the refrigerator is a little copper one. The shutoff is in the basement where it is accessible. I thin the leak is within the refrigerator itself, not the line going to it. The water came from the base of the refrigerator. I am not familiar with the moisture sensors. Can you give me a name I can search. I'm, guessing they don't make a pan to sit a refrigerator on, is that correct? Maybe a rubber mat? At least that would have forced the leaking water out where we could see it before it did any damage.

Sorry to hear about your leak. I would definitely try to dry out the area the best that you can. Use a dehumidifier, if you have one or can rent one, and use some fans. I'd double check all of the water connections for the icemaker, as well as the water line itself. If the icemaker is turned off, I wouldn't think that you would get a water leak. While not on turkey day, our fun the day before Thanksgiving was having to replace our hot water heater. Fortunately, DW noticed the water on the floor around the water heater, before it had spread far. We spent most of the day trying to get a new one in. We bought one from Lowes, got it home, unboxed it, only to find that it was dented. So, we took it back and got another one. Thank heavens that it didn't happen on Thanksgiving day. We wouldn't have had hot water until today. When DW was at Lowes, returning the first water heater, there was a lady there trying desperately to find a new range, as hers had died. What is it about the holidays that appliances like to act up around? This post was edited by gpraceman on Fri, Nov 29, 13 at 13:19
