Open Thermistor on U-Line

I have a flashing light on my U-Line drawer refrigerator which indicates an open thermistor. The unit is also frosting on the back panel - is this likely to be caused by an open thermistor. Is this something I can fix myself and where can I find instructions?

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

Hello. Your model dryer has a service flash on the lower door strike/catch concerning not staying closed or not closing properly. If the door is allowed to open too much, the door switch will not be closed and the dryer won't run. The part number for the new kit is 279570 and it includes 2 door strikes and several catches. You choose the ones you need. However, if the door *is* closing properly, you can put the unit in diagnostic mode(door closed, all indicators off) by pressing/holding any button *except* stop for 2 seconds, then releasing, press/hold 2 sec, release, press/hold 2 seconds, release-- all the indicator lights will light for 5 seconds, and an 8 88 will be shown in the display. If there are *no* active fault codes, the indicators will momentarily turn off and then stay on with the 8 88 displayed. If there is an active fault code, it will be flashing in the display. (ex. would be an "F" and "xx" where "xx" would be a number.) If you press the same button you originally pressed once, then again, then again, the most recent code will be displayed, then the next, and so on up to 4 stored codes. To turn off diagnostic mode, just press stop. I hope this helps you!

All od the sudden my side by side ge artica keeps refridgeratoor at about 40 degrees and freezer at about 16 degrees


Open the freezer and look for frost buildup on the back panel. If you see frost, you have a defrost problem. Possible causes are the defrost heater or evaporator thermistor. You will need a multimeter to test the components. The heater should show continuity. The thermistor should be between 10k and 80k? at fridge to freezer temperatures. Anything less than that, the thermistor is bad. Remove the back panel of the freezer to access. The heater is mounted to the bottom of the evaporator coils. The evaporator thermistor is mounted to the top of the evaporator.

If no frost, I would suspect the freezer thermistor. It's at the left lower rear of the freezer or behind a grill on the right wall of the freezer. Same thing, if it reads less than 10k? replace it.

If all the components check good, the only thing left is the main control board. You can find this behind a panel on the back of the fridge.

Part numbers: Defrost heater WR51X10055, thermistor WR55X10025, Control board WR55X10942.

Refrigerator not cooling freezer works fine blower motor in rear of unit on but turning slowly


Since the freezer is fine, you are in good shape. Pull off the back cover inside the freezer to inspect the evaporator coils. You should see a light frost pattern. If it is heavily frosted, then you have a open heater element - located at bottom of evaporator. If heater is good and you have heavy frost buildup, replace motherboard and thermistor which is clipped to the top of the evaporator.

Blinking light on 2075DWRRB


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

Uline under the counter two drawer refrig seems to be running very hot, with ER blinking on temp gauge inside top drawer


Hi
Er means that somthing is wrong. It could be a temperature problem that caused it. Does it beep at all. That is a alarm for the door being open. You may need to check the magnet on the door and the reed switch on the wall. Upper left for the top drawer. and on the bottom is on the grill and door. Normally this is something I would ask for a tech to look at. But if you feel confident to try this I can get you into the program to see what its telling us. Now hold the up arrow and at the same time press and release the light bulb 3 times. Then release the up arrow last. If you did this right then you will have a 0 on the display. Yes, Then up arrow until you get to 3. Then press and release, It should give you a number. E# ? Let me know what this is. You may have a couple so write down all of them.

Now after you got the number then just push up arrow until you get to 99 then press and release the light bulb to go back to the refrigeration cycle.
E3= bottom drawer open to long
E10= Top drawer open
E1 = Thermistor #1 open
E5 = 10 degrees to warm E6 = 10 degrees too cold E7= Thermistor 2 E8=Thermistor 3 E9 =Thermistor 4 open thermistor 1 located top drawer Thermistor#2 I/M or evap if no icemaker
Thermistor3 is located in freezer or base if no freezer thermistor 4 is drain pan
Hope this helps
