Samsung fradg It can't defrost

It will either be a fault with the Defrost Timer, or the Defrost Heater. Samsung have a different approach

If the defrost sensor fails to shut off the defrost heater, the fuse will blow in order to shut off the defrost heater. If the defrost sensor fuse blows, the defrost system will not work, and the refrigerator will not defrost. ... If either the defrost sensor or fuse does not have continuity, replace the defrost sensor.

sounds like a defrost issue defrost clock heater or limit could be bad

If the microwave oven is not arcing on the inside, and seems to cook fine then yes it is okay to use.

If it is a frost free unit the water collects in a well at the compressor , there is a heater element in the well that boils off the water , this is were the fault is.

Access is from the rear, but make sure the vents on the front grill are not clogged also because it does need front to rear air flow.

Your unit has two evaporator coils and two defrost heaters and two defrost thermostats, but uses one defrost timer circuit. So if you don't have trouble with the freezer side, then it should be the defrost heater or defrost thermostat for the refrigerator side of your unit. Which are items 1-2 and 1-4 on the following diagram.

Here's a link to a very good explanation of the defrost circuit. You can check the defrost terminator by disconnecting it and measuring with an ohm meter. The relay contacts can be checked with the ohm meter if you unplug the fridge and manually advance the timer. The motor and and other parts will be checked with a volt meter at different points in the cycle with the fridge paoered up and running. If you're building up ice, there's an issue with the defroster circuit - or the defrost drain tube is clogged with ice.

If the defrost circuit is working and tube is clogged with ice - thaw it out. Hang an aluminum or copper wire from the defrost heater into the drain tube. Make sure the wire hangs slightly further into the tube than the ice formed inside. This wire will help conduct heat during defrost mode down into the tube and help prevent ice from forming.

If this was helpful, please rate it "4 thumbs up". Thanks!

All newer refrigerators have a defrost assembly, but you shouldn't notice it defrosting your food, it should just come on for awhile and then kick off.

If the freezer is defrosting your food then there is a problem.

I have a Samsung fridge model no. RS2556sh. We lost power and when the power came back on the fridge did not. The LED is blinking in the top right corner and the lights or on inside the fridge but not cooling in either side. It doesn't sound like the compresser or any of the fans are coming on. So, what's wrong?
