20 Most Recent U-Line CO2075F-B Echelon Refrigerator Ice Maker Combination Questions & Answers

Icemaker Fill Tube Freezing Make sure the water supply is greater than 20 psi. If too low, the water valve won't seat properly and it'll "weep." Common causes of low pressure are gunked-up saddle tap valves, kinked water supply line, and using a reverse osmosis filter to supply water to the icemaker. Check to see if the black, flexible portion of the fill tube is wrinkled, twisted, or kinked which can cause ice dams that block the fill tube. It turns out that the manufacturer's have been scratching their heads about this, too, and have concluded that the new fill tube air slit design helps prevent this problem.

some times if the water inlet valve has a small drip it will leak into the flume and freeze up and stop all water from entering

U-Line CO2075F-B... | Answered on Nov 22, 2013

You have a bad water valve, this causes water not to stop entering the unit and causes one big cube. You didn't mention any ice or frost behind the ice bin so I will assume you have none. the water valve should correct this issue.

Good Luck

Over time the inlet valve becomes partially plugged, reducing the outlet pressure and reducing the water flow rate into the icemaker. If the flow rate is too low then the water will gradually freeze in the tube until it becomes blocked entirely. Many times low water pressure will cause this. You can perform a taste. Get a piece of tubing and attach it to the inlet valve. Run this piece to a container and see if you get any water while the power is off to the valve. You might have a valve that is not shutting completely off. Hard water might cause this. Killing the power to the valve will make the valve inoperable. Actually the purpose of killing the power is to see if the valve is allowing water to bypass even when there is no signal from the switch to do so.Bad inlet valve could be the possibility. So it needs to be ordered and replaced because the valve isn't sealing off properly and it's causing the water to trickle through or drip through the fill tube sometimes, then it freezes before it reaches the icemaker and over time it will clog up the fill tube completely.

Sorry to hear about your problem. Sounds like you have a defrost issue. Hence your unit is not defrosting. All of this apply's if your freezer side has ice on it. If not. you have other issues, this does sound funny, but this is why your refrigerator side is warm, or not cooling.

Here is a list of some things that can go wrong.
1. Defective heat coil
2. Defective defrost timer
3. Defective defrost sensor
4. Defective Fan
5. Defective compartment inlet damper (on some models)

You should call a service company to resolve your issue.

My ice cube chute kept freezing, and I realized the Access Door was stuck open. I was able to replace it without taking the door apart.

Well sounds like your ice maker evaporator drain hole is frozen, every time the unit goes into defrost cycle, water backs up and leaks down to the drawer. You can try turn off the refer for 48hrs with the doors open, most case it will reset by it self. If it is happening again in few weeks, then you evaporator drain pan heater is not working. Also make sure the doors are shut all the time.

Thermistors are calibrated together with the board. When you order a board thermistors will come with them. When you get the board (display) a thermistor will be with it. You will have to pull unit out. remove the back panel and you will see the wires for the thermistor on your left and it plugs into the right side. That should help you. just remove permagum and pull the thermistor out. It just site in a tube.Part number for that model is 68005

OK I'm guessing you have a clear icemaker. Not a co2075. When you replace the board you MUST replace the thermistors that come with the board. The board and thermistors are calibrated together. What is your model number? A clear ice maker has thermistors inside tubes. Except for the one on your filter dryer. Lets start with the correct model.

You need a service guy to look at it. It could be water leaking or a simple case that the flap isnt sealing and the ice melts and then freezes the flap open

P1 means a problem with your drain. Most of the time its a kink in the line. Double check your drain line or it could even be a bad drain pump.

It might be a bad thermistor. I would need the exact model number. It could be a open harness as well.

too much water going into it. Decrease the water remove the cover and you will see a screw with a spring around it. Turn it clockwise to decrease the water.
