Daewoo frnu20da Water/ice dispenser supply

I wouldn't buy a Daewoo fridge with Donald Trump's money!

You either have a faulty thermostat, a loose connection or most likely a build up of ice inside the freezer. I had the same problem. Almost replaced fridge. Took all the food out one day, took out the racks and disassembled bottom and rear and found a two foot log block of ice inside air return. Removed ice everything works perfectly.

Just a thought i would check if there. Is it possible an ice build up around the fan could be stopping it from turning?

your cooling matchine get damaged,there having a cooling matchine.

Look on the back of the unit for a plastic hose coming out the bottom to a drain pan usually sat on top of the compressor. Bend a straw and push up inside. If it won;t go, there is a blockage, usually ice in the drain. Fully defrost the freezer and blow through the straw until clear.

Sounds like you have an airflow issue. Freezer temp. should be @10-15 below and fresh food area @35-37 above zero You may have an evaporator fan or door switch failure

it go's down locate drain tube at bottom of freezer some time just defrosting manually will cure this drain gets small peace of food or tie from food freezes and blocks water from flowing warm water and a turkey baster works wounders

The water filter should be changed every six months, not two years.
The water lines may still be frozen even though you turned the unit off, but most likely you are not getting water flow due to a clogged filter. Change it.

the thermostat in the ice machine is not working. its most likely tha the icemaker is a FSP whirlpool it's a lot surer to just replace the hole head and be done with it unless you'd like keep dealing with it.
