Samsung RB195BSBB bottom freezer not cooling

The freezer is not cooling. first we cleaned out the back coils. then found that there was ice buildup showing through the holes in the back of the freezer. so we defrosted that. now it is cold enough to barely keep the food frozen and the temperature on the digital readout on the door says 2 degrees but we put a thermometer in the freezer and it reads 20 degrees. fan is running and compressor is warm. what are we missing?? does the digital control panel have anything to do with it? thank you for your help. carol

If the ice buildup was by the pipe just going into the evaporator in the freezer compartment and the suction line going into the compressor is warm to the touch and not cold and/or sweating you are low on freon.

If the entire evaporator was buried in ice, the ice covering is also serving as an insulator and preventing internal temps from going down any further. There is a problem with the self defrosting mechanism which is designed to prevent the ice buildup. Could be either the defrost timer, defrost thermostat or the defrost heating element. Hope that it is just the heater element. If you have an electronic module for the rest you are in for unpleasant surprise to replace the unit. Proprietary parts mucho expensive plus labor.

Until you fix it, just let the unit manually defrost (U can use a hair dryer to speed it up) and turn it back on again. It will work fine till the ice builds back up. Keep opening and closing of freezer compartment to minimum to minimize moisture laden air that enters compartment.

When you have an ice problem on the evaporator coils, the problem is usually the defrost timer is bad. On this unit, the timer is located on the main control board.

Sounds like the compressor is trying to start. Shut it off overnight. Try re-starting. If it still clicks you'll need a service call.

SOURCE: ice build up on coil inside freezer

it can be two things the refrgerator probably has a small refrigerant leak therefore it ices up, or the defrosting heater on the begining of the coil is faulty.

How do I remove the back wall of freezer on samsung rb195acwp

Annonymous, what problem are you trying to solve? Is the water at the bottom of the refrigerator because the fridge is not cooling? If that then unplug the fridge, Keep the fridge and the freezer doors open after salvaging food items. Keep it unplugged for about 12 hrs and any ice buildup in the back wall will melt. You will see a pool of water on the floor. Clean that and the inside of fridge and freezer. Re-connect. You might get lucky!

Cleaning & Maintenance

From general experience (I'm 55) : Depends on where the heat transfer coils are; on the back or the bottom or both. If on the Back: should be cleaned with a brush & vacuum at least every 3-6 months. If on the bottom, about every 2-6 months. Bottom coils can usually be accessed from the front by opening the door/ removing drawers and pulling off an access cover. Bottom coils also usually have a Fan that can get clogged with dust/ mice(Yes! Mice.) that hurts the performance also. May have to pull it out and remove a back cover. For the rest, Check the condition of the door seals and replace any that are not completely closing. Keep the seal surfaces and the insides clean. Defrost regularly (every1 to 2 months) to prevent ice buildup. Some units also have interior fans, that are supposed to function when the unit is attemting to cool.

The cooling coil in the back interior of the fridge forms frost and then melts to form a lake in the bottom of the fridge, and then it freezes. The produce drawers freeze shut from the buildup every weeks...

First I would check the fan in the freezer. Listen to see if it is running
It moves air to the ref from the freezer
Then check to see if freezer control is turned WARMER, which makes the Ref. colder
Also this might be a common Defrost problem, Ice
is not being melted by the defrost system.The fan can't blow through the coils into the fridge.
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 fan undernearh Ref in the rear
Clean condenser coils underneath
Check cold control (thats where you turn it colder)

Check the back of the freezer and see if it is iced up in there sometimes you get an ice buildup and have to defrost the whole thing to get it to start working

Have you cleaned to condensor coil on the back of the box at the bottom where the compressor is at take a vacuum cleaner and clean the coils see if this helps sounds like you have an airflow problem.

Refrigerator is not very cold. Freezer is not

Our side by side did the same, started because the cooling coils on the bottom (although cleaned regularly), still overworked due to build up of dust and especially pet hair. The heating coil in the freezer compartment which prevents ice buildup in modern (frost-free) units kicks on full time and the compressor can't compensate, thus your perishables start to thaw. Luckily we were still under warranty. hope this helps you at least start diagnosing the problem.

Refrigerator will not cool

Check the fridge thermostat with an ohm meter. It will turn on & off at room temp. You can also dip the bulb into a glass if ice water to check it.
If the freezer is working okay, you have a buildup of ice in the transfer tube. Remove the freezer walls. Use a hair dryer to melt the ice buildup in the bottom & rear of the freezer. Look for mouse damage where the tubes enter the rear of the unit. Make sure the drain pan & tube under the cooling coils is clean.

Frigidaire model # FRS26ZNHB2 side by side not cooling

From your description, you have a bad evaporator fan motor. The part number for a replacement motor is #5304445861.This is not a direct replacement but is more reliable.Remove everything in the freezer, take off the back panels and you will see the fan.
If there is a large frost buildup on the coils and the fan is turning you have a defrost problem. If that is the case, please call me at 334-347-0000 and I will walk you through it.
