I have a U-line 2075dwrr duel drawer unit. It has a freezer and ice maker in the bottom drawer and a normal fridge drawer on the top. Lately, the top unit is not staying anywhere near cold. 60 degrees when it's set for 36. The bottom unit is working fine, staying frozen and making ice and the fan is working too. I'm not sure why the top isn't cooling. Any help?

Locate and check the valve that feeds water to the icemaker.

Is the freezer section cooling properly. If yes, then problem is drain hole blocked in freezer section.There is a water drain hole, which runs to the drain line.But if the drain hole is got clogged by ice, then water will leak from other end and you get water in bottom drawer.-------- try manual defrost procedure.----------

The manual defrost reset procedure is as follows : ----
First unplug the unit from main power outlet. Then empty whole unit completely. Then keep both the doors open. Wait for 24 hours. All the ice collected on the coils and in the freezer section will get melted. Clean the water from the sections. Then Connect the power cord of the unit to main power outlet after 24 hours/.Then set the temperature to normal in both fridge and freezer section. Then check, do you notice the same problem, if yes then defrost assembly board is faulty.But in most cases defrost reset procedure helps.----------- Thanks.Helpmech.

A common problem. All modern refrigerators have an automatic deicer. The heater kicks in, then MELTS the ice in build up in the freezer for a short period before freezing again. This water drains either in the fridge or out the back to the catch tray. Simply pull out the bottom drawers and clean the clogged drain hold where the water can drain and evaporate in the catch tray as it is designed to.

I turned the fridge and freezer off using the circular dials, I then turned the unit off at the mains. Left it for a few minutes and then turned the power back on. I then turned the circular dials to "max" and then depressed the super cool and super freeze buttons to turn this facility on. This time they came on normally (not flashing) and no alarm sounded. The fridge and freezer then started to get cold. Once the unit had been running for several hours I then turned the dials to the 3/4 mark and depressed the super cool and super freeze buttons again to turn them off. Over night the fridge and the freezer appear to be working properly so I hope that my problem is solved. Maybe the unit just needed to "settle" before being switched on?

Find the drain line from the freezer to the evaporation pan near the motor. Often the line is visible on the back of the fridge. That line is plugged either with food residue or the collection point in the freezer is solid ice. The self defrost feature melts the frost and drains it to the evap pan. If you remove the floor from the freezer area, you will see the collection point. When the line gets plugged with food, no water drains and then freezes to block the line even worse. So, if there is ice at the collection point, remove it somehow, maybe a hair dryer, and then clear the line by blowing compressed air from the bottom of the drain hose through to the collection point.

the defrost drain in the freezer is clogged with ice.
empty the food from the freezer, and put through a defrost. you might have to help the fridge defrost with a hair dryer. you may also have to remove the rear panel (inside the freezer) or pending on the model to bottom panel of the freezer.. (usually held in by 1/4" hex screws.)
melt all the ice, and be sure that the drain is clear, and it should work.

NO SOLUTION!!!!
a ?
how do i stop it?

the water line comes from the bottom back of the fridge it sound like you have a blocked line meaning
you have a bad water replace valve and clean out line

Look on the bottom of the rectangular motor housing for the ice maker. This is the white box that holds the front end of the ice tray. In the past, this was normally a small patch of black 'runner' that covered the switch and helped kkep moisture out.

If you cannot locate it by feel, try using a small mirror and a flashlight to help you locate it.

Very curious. When you say the tube to the ice maker was disconnected I am unsure as to which tube you are refering to. However hopefully a few pointers might help a damsel. Most units have the water supply enter into the cabinet through a two way water solenoid valve (i.e. one for chilled water one for the ice maker). It then normally enters the top of the freezer section for the ice maker. It then drops down inside the freezer section to the icemaker module. Therefore the only control over the water for the icemaker is the solenoid valve which is controlled by the icemaker "module". A trick is to switch the control at the solenoid valve so that you can use the chilled water dispenser to check if the water valve for the icemaker is working. If it is then you probably have a problem with the icemaker module or the temperature in the freezer section (which you would probably have noticed if that was the case). If you have a problem with the module then you normally have to replace the module as they dont like supplying spares for modules.
Anyway hope this is of some help and good luck.

ps model is normally near the salad drawer or top of the fridge section dependent on brand.
