Refrigerator warm and defrost heat sheath and coil frozen solid

I have an LBRN20520WW bottom freezer refrigerator. Lights 5,6 and 7 come on every day. When you unplug it and plug it back in the refrigerator resets and runs for 24 hours and does it all over again. I have to manually defrost my freezer every two weeks.

Evaporater coil was frozen. Thawed out. Fan is running. Refrigerator was warm. Restarted, refrigerator warm. Freezer to cold frosting. Dampner to refrigerator not staying open.


My first guess is defrost timer, is stuck in defrost, if you can find it, turn it, and if the compressor and fans turn on, you got your answer.

Top refrigerator warm bottom is ice cold.


An automatic defrost time turns the defrost cycle on and off every 24 hours. If problem continues, problem is most likely defective defrost timer.

Even electronically controlled units often have electro-mechanical timers for defrost cycle.

Not blowing cold air


Most likely evaporator coils are iced near solid...few hours unplugged would have helped just a little...needs major defrosting though.
The automatic defrost cycle will never fix it when it gets this bad...if it's still working yet.

I have one of these and have had to use heat gun/ hair dryer more than once to defrost it.

Probably the cause...which will need fixed or it will do it again sooner or latter...is the melted frost/ice goes down a little drain tube and dumps into tray to evaporate above coils...this tube gets plugged first with dust and then when melted frost drains and stands in tube the tube get plugged with frozen water.

You see it is important to unplug or fridge will self destruct.

Refrigerator on the fritz


The defroster is not working. Ice build up prevents cold air from the freezer chest from blowing into the lower part.

The way the defroster works is this: There is a defrost timer, probably found under the refrigerator at the front, that turns on the defroster three times per day or so. That turns on a heater nested among the freezer coils. It keeps heating until the defrost thermostat gets warm; then it quits defrosting.

I think your defrost timer doesn't turn. You can turn it with a screw driver till you hear a click. Now your ice compartment should be defrosting. With ice buildup it may need lots and lots of defrosting. You might not get cooling back into the lower part for awhile, till the ice buildup melts.

By the preceding, you should know if the defrost timer needs replacing.

If you should need to manually defrost the freezer coils, they are, I think, under the floor of the freezer. To defrost them, I'm told, a hair drier works better than boiling water. The defrost thermostat is in there too, a one inch unit with two wires. It should have no continuity warm, closed circuit frozen. If it has open circuit frozen, that would be your problem.

Samsung French Door Refrgerator - New


Only two months old? Couldn't you complain to the store?

The way the defroster works is this: There is a defrost timer under the refrigerator. (I'm guessing based on other brands.) That turns on the defroster about three times per day. The defroster is a heating coil with the freezer coils. It heats that until the defrost thermostat gets warm; then it quits defrosting.

My guess is that the defrost thermostat doesn't turn off the defroster... that it continues defrosting until the defrost timer turns the defroster off.

So if you want to fix it yourself, dig into the defrost coils. I don't know where to look on a French Door refrigerator. Find the defrost thermostat, an inch wide unit with two wires. Test it for continuity while it is warm. There should be none. Frozen there should be continuity.

Hope that helps.

Refrigerator won't get cold


You likely have a defrost cycle failure. The freezer's cooling coils need to be frosty and cold so the air that the fan pulls over them can cool the fridge section. If the defrost cycle fails, the coils freeze up to a block of ice and air flow suffers (fridge is about 55 degrees F). The freezer stays cold only because there's a block of ice in there now... sometimes that cold "sinks" to the bottom and only the food at the bottom stays frozen (and can even freeze food at the bottom of the fridge compartment while the rest is warm). To be sure, you'll need to take the rear interior panel off the freezer back wall and check the coils to see if they are frozen solid. If they are then there's a defrost cycle failure. If they are showing a nice white frosty pattern evenly all over the coils then that's normal and maybe the evap fan (right above the coils) is not blowing air up properly or is not working at all. That fan should run if the compressor is running, etc. the only time it doesn't run is during an actual defrost cycle. Once you find out what condition the coils are in it should be simple to direct you further on the problem.
