I've replace the water filter and the icemaker module, all to no avail. I've turned everything off, then back on. I'm not sure what to try next. Any help out there?

About a year ago we had a Samsung tech out to our home and he replaced the heating element that runs along the sides/bottom…parts and labor ~$200. As you can see from the attached picture, the bottom portion seems just fine, so it’s not the drain jamming up, for which I’ve seen some parts that can be bought to conduct more heat to the drain hole. Something is happening to quickly accumulate ice in the upper portion…assuming it’s a leak of sorts? The noise is starting to brew again today, so this week I will be back into the fridge for a defrost…any recommendations for a more permanent solve? Thoughts on a copper wire wrapped around the heating element and extended to the upper portion to conduct some heat up there to avoid the ice build up? Sorry if this is a naïve question, but is low freon a potential issue here? If so, how to diagnose and/or recharge?

The fridge works fine otherwise…some freezing of the upper ice maker a few times a year…but general cooling is working…so I’m hopeful that there’s a simple MacGyver fix here that will keep me from clearing the contents of the fridge and defrosting every 4-6 weeks in the summer months. Thanks in advance for the help.

As an update, we are experiencing the re-occurrence of fan noise routinely around every 4-5 weeks...I'm getting rather swift with the removal of contents/shelves from the fridge and hair-dryer defrost of the back wall...can usually have all put back together within 40-60 minutes. Build-up seems faster in the summer months where the humidity is higher here in WI...it gets dry in the winters and I'm expecting that we can go months if I can gut through the summer. With inspiration from the video linked below I've purchased an SH502 heater for ~$20 from Amazon and intend to install one of the next times we open up the unit...unless someone advises otherwise in this thread. Condensation is appearing quickly even while I defrost...so maybe a little caulk on the entry point near the top will be in order too.

Bought this refrigerator couple years back. All is good, until a few hours ago... as water stopped coming out of the dispenser. Recently (about a month ago) changed the water filter (used Samsumg filter) and all was well until today.

• - Note that water stopped coming out all of a sudden. My wife used it a few minutes ago to get some water... but now no more water comes out of the dispenser.
• - When I remove the filter, water is getting dispensed at good speed, but when I put back the filter (the same that I was using the last 30 days), water stops.
• - I bought a different filter and see the same result. Not even sputtering (the thing that usually happens the first few minutes when a new filter gets inserted)... it's like blank.. no water at all.
• - Can hear the humming sound when the dispenser gets clicked.
• - No leakage.
• - All the other lights on the control panel are glowing.
• - Emptied ice bucket and see that new ice is being made.

I’ve tried to reset, checked the arm for frozen ice, checked 100+ times to ensure it was put back into the freezer properly, and nada.

I’m typically a “pro” at fixing just about anything, including the “motherboard” on my former LG frig. So not being able to figure this one out has me extremely frustrated.

Any help/ advice would be appreciated!

Thank you!

Nikki

I tried to find the why for more days now, and am now on my way to give up.

I have a RSH1DTMH american fridge-freezer, and have some problems on the freezer part, fridge working well after mooving the temperature sensor.

Freezer is not freezing, i can’t tell at what temerature it keeps, but certainly above 0°C because water put in stays a water.

I checked the temperature sensor with the ohm meter, and it seems OK, checked the defrost heater (manual forced defrost) - works well, and the fan inside the freezer - is OK.

I’m not sure where is the defrost thermostat, i see 2 pieces that looks similar to the thermostat I saw on some videos on youtube treating different fridges, but i’m not sure if it’s this and anyway seems more complicated to get out because the wires going out of it doesn’t go to one place.

What’s more when the fridge is turned on I can see that the freezer is trying to do something, because after few minutes you can see a lot of frost on one tube. The other thing is that temperature on the panel is getting lower to reach after a long time the temperature that I set so -19°C. It takes a long time, between half a day and one day, but finally it shows and stays at -19 but that’s not right, because the water put inside doesn’t even freeze.

Join some pictures to show what I’m trying to explain :)

Any help appreciated :) !!

It went into forced operation, but it didn’t make any sound.

I mesured again the sensor while the dispaly is showing -25°C, I join the picture because I’m not sure if I did it with correct setting of ohm-meter.

here’s how it’s frosted at the moment

my estimation is that it’s around +20°C inside the freezer

And here is the image of the temerature sensor

It was attached to the tube going out of the silver reservoir with a plastic attach but i took it out to be able to disconnect it totally

More info. The ice dispenser works fine so that ruled out the microswitch. I even tested the microswitch separately with a meter. works perfect,

I look forward to hearing from some more experienced folks out there

Freezer is not cold enough to keep food frozen and ice maker is not making iced.

Both the freezer and fridge are going way out of temperature. When unplugged and immediately plugged back in, the control panel inside of the fridge will display the accurate ambient temperatures and both the fridge and freezer will proceed to attempt to cool to their set temperatures.

The control panel then seems to get "stuck" on those temps after a few hours and stops displaying temperature accurately / never fluctuates from the set temperature. The control panel will display the set temps at 34°F and -4°F, whilst a separate thermometer inside reads the fridge as being between 40-45°F and the freezer at 35-40°F.

Coils in the back are clean, compressor fan seems to kick on, and the evaporator fans are not frozen. Didn't see any error codes on the control panel and no blinking lights on the PCB. Seems unlikely that both temperature sensors would be faulty, right? Especially since the panel displays the correct temperature when the fridge is unplugged and plugged back in. What else should I be checking?
