    Had the serviceman out today. He diagnosed a failure on the motherboard that tracks the need to defrost. Ordering a replacement motherboard. Ouch $$$$$.



    Tells me these are prone to fail if we have frequent power outages (we do), and recommends surge protection for the 'fridge.

SOURCE: Freezer keeps loosing its temperature and then freezes again

Sounds like a pc board problem. I have come across many units like these (although I don't know the Samsungs!) which have similar symptoms...it would seem like the freezer gets stuck in "defrost" mode and the ice would melt etc.etc.... In most cases replacing the electronics module solved the problem...in hindsight I have figured out that it was moisture on the pc board components that were to blame! So as a first resort I would locate the main electronics board and use a hairdryer to dry out thouroughly (even if it seems dry!) Also check values for temperature sensors....don't know what the specific values for the Samsung NTC's are, but normally they are in the low kOhm's.... Oshie

It has a plugged defrost drain. You may need to defrost for 24 hours with unit unplugged and doors open. UNPLUG FIRST!! f still leaks, you need to remove floor of freezer, then the back wall of freezer. Remove ice. At center rear under coils is the drain hole that is plugged up. Use hair dryer to melt ice. Pour hot water in this area to uncover drain. With hot water in area, you can put a 1/4 diam. hose or copper pipe in drain and blow into it while pressing down. It will slowly go through ice, clearing drain.

SOURCE: Water collecting in refrigerator and ice collecting in freezer

sounds like you have a clogged defrost drain tube. removing back panel of freezer will give you access to drain trough, melt away the ice with a hair dryer, youll find a drain hole under there somewhere,pouring boiling water down the drain will clear it pretty quickly( i use a steam machine purchased from the infomercials works awesome, after you clear it and all water drain down tube wrap a piece of solid copper wire around the heater( black heater right above the drain trough) and stick it in the whole maybe an inch or so. now every time the heater comes on to defrost it will prevent the hole from freezing over

SOURCE: Cold Freezer Hot refrigerator

I'm having the same problem with a Haier Model HTE18WAAWW.

Water is dripping into refrigerator section from the freezer section. Eventually, refrigerator section was not cooling adequately. Freezer was freezing, but there was eventually ice crystals inside similar to hoarfrost. (See Google images for hoarfrost if you're not sure what hoarfrost is.)

I turned off and unplugged unit for several hours while I removed the floor pan and internal back panel in the freezer. There was ice built up in the evaporator drain pan that was blocking the air flow of cold air from the evaporator into the refrigerator. I melted the ice with a hair drier plugged into a GFI outlet for safety.

I dried everything off. I could not find evidence of water going down the condensate drain tube below the evaporator to the condensate drain sitting on top of the compressor. I tried running a coat hanger down the drain line to no avail. I poured hot water down the condensate drain line to no avail. I put everything back together. Works fine as far as cooling and freezing, but water is still dripping into the refrigerator.

I think the defrosters are okay unless the heater strip below the evaporator is burned out. I base this on the fact that there is no condensate around the door gaskets even though the temperature in the house is hot and humid. I may have to Ohm that heater out. I'm thinking the drain line is clogged for the condensate drain. It may need longer defrosting.

If longer defrosting don't work, I'm thinking I need to rethink how to clean out the condensate drain line. Maybe low pressure compressed air???

SOURCE: Defrost Timer Prroblem?

Refrigerator not cooling, ice forming on back of side-by-side freezer:
Turn off unit. Empty freezer section. Remove freezer back panel (4 screws) to expose iced-over coils. Use a fan to speed up defrosting. Put a towel or a plastic drip pan in the bottom of the freezer to collect melting water (rather than letting the water collect and maybe overflowing in the drip pan underneath the refrigerator).
After defrosting, by temporarily replacing the freezer back panel and turning on the unit, the refrigerator may operate OK for about 3 weeks before the next excessive ice build up.
Possible problem- a burned out Defrost Heater.
To check: After defrosting, turn off power to or unplug the refrigerator.
Unscrew the Defrost Heater bracket (2 screws). When loose, unplug the two wires connected to the unit. Have the unit checked, or use an ohm-meter to check continuity. If unit measures "open", high resistance, replace the Defrost Heater and bracket. If the heating element shows continuity (or low resistance) the heater is probably OK and you have another problem. Now you may need to contact a repair man.

How does to defoze refrigerator


Generally, if you unplug the refrigerator and set the freezer and refrigerator temperature controls to off then plug it back it, this will put the refrigerator in forced defrost mode. Keep the doors closed and allow defrosting to last for about 20 minutes. Then unplug again and reset the temperature controls to mid-range or a little above, and plug it back in. If this does not reset the defrost cycle, you probably need service.

The top half of the refrigerator has started to get warmer over a couple of days and now appears the top half of the shelves and cooling has stopped working. The temperature has dropped very quickly over...


Hi,
I'm Leo
This is a common defrost problem, The ice
is not being melted by the defrost system. he fan can't blow into ref.
Take out back panel of freezer to check for ice buildup. The coils should be clean.
There are three components to a defrost system- a heater,heater thermostat, and a timer unless you have a defrost electronic card.
Its best handled by a Technician but you could possibly do it by taking your model number to the nearest appliance parts store and asking for the parts. They are mostly located in freezer ,behind back panel on freezer coils.except the card which is usually located in ref The parts store will have info
Also check evaporator fan in freezer
Also check fan undernearh Ref in the rear
Clean condenser coils underneath

Kenmore refrigerator(model 10653606202) freezer is cooling, can hear the circulation fan' noise, also see defrosted water in the bottom collection pan. but the refrege is not cooling.


If the freezers is freezing everything and you can hear the circulation fan, maybe it is a defrost problem. Sometime ice will build up behind the rear panel in the freezer section that blocks either the chilling tubes to the refrigerator section.

You will need to remove the food from the freezer, then remove the shelves and inside back panel of the freezer. If you see a lot of ice, that is probably your problem. DON'T use water to defrost, either unplug and let it set with the door open or hurry it up with a hair dryer.

It also means your defrost assembly has stopped working and will need replaced, but the unit will work without it for several weeks before the ice build up redevelops.

My Samsung RB195BSSB bottom freezer model has recently developed an issue. The freezer will warm up to 21 degrees and not hold the previous temperature. Fridge is fine. Ice maker may not be making ice...


This sounds like there is a build up of ice on the evaporator. this will block the air flow and allow temperatures to rise.
The problem could be with;
\ the defrost timer
\ defrost heater
A technician can solve this for you

Stops cooling ice melts and leaks water on the floor


That model refrigerator uses the mother control board for deciding when defrost is to take place. It has no defrost timer or Adaptive Defrost Control like other refrigerators. This sounds like *********** board part number WR55X10942 is malfunctioning. The board decides most functions of your refrigerator. Until the board is replace I do not believe the problem will resolve itself. Thanks, Sea Breeze

The display unit keeps flashing on the fridge side on my samsung RS20CCVS.


When the temperature indicator flashes indicate then the temperature has ridge a level lower the the set temperature for example if you set you fridge side to 36 degree and and has fail to stop from getting cooler and has ridge 34 degree. some times those friges fail to calibrate them self tray by unplugging you dirge for 30 seconds and replug it then the board will auto calibrate for the next 24 hours If this problem comes back again that meas than your defrost element on the fridge side is bad.

Zanussi Electrolux frost free fridge/freezer - freezer defrosting


My husband left the freezer door open a couple of months ago, causing ice to form. The loud rattling noise was the fan hitting the ice. The reason why the temperature started to rise but the noise stopped was because the fan had got stuck in a block of ice and was no longer working. Simple solution - defrost the freezer for 24 hours. Touch wood, it is all working fine now!

Not cooling or freezing


When the compressor is running, both the fan inside the freezer and the fan down by the compressor should be running. If OK, look for frost on the back wall of the freezer, indicating a probable defrost heater failure. If yes, remove back metal cover in freezer, defrost with hair blower, replace defrost heater (the thing at the bottom of the freezer coils with two wires going to it)
If no to these, send me an "ask me" follow up question.
