Samsung fridge RS2545SH every 7 days freezes fridge coil.
I would like more advice on how to test and locate the thermostat. I am very familiar with using multimeters. This is an all digital display on the front that tells you the temps and stuff. Im not sure where the thermostat is located. I did find the defrost heater built into the evaporator coil in the fridge compartment. Any help would be appreciated.

Good day, The defrost system is made up of 3 parts. The timer, the defrost thermostat and the main heater. The most common item to fail is the defrost thermostat which is clipped to the top of the cooling coil, located behind the rear panel in the feezer problem. It looks like this.
It can be tested with an ohm meter and should read zero ohms. It must be tested while still cold. If allowed to warm up the test will fail. If it tests O.K. then the only item left is the main heater. It will usually test at less than 35 ohms. If it test infinity, then it will have to be replaced. It may be a single heater or a set of 2 but without the model number I cannot give you that information.
Check rear wall of freezer by feel for frost. Heavy, even frost indicates likely problem in the defrost system. Unplug unit. Defrost heater (in freezer behind rear wall panel), defrost thermostat (same area-must be checked at freezer temperature) or Defrost timer-located lower back outside of unit. Near compressor. Do continuity test on heater and defrost thermostat and if they show continuity (good), replace defrost timer. If not, replace the one that tests bad.
Defrost coils fully. Reassemble.
Please let me know if I have helped with comments and rating.
Refrigerator will work about 7-10 days after being defrosted until thick frost builds up again cutting off air flow to both compartments
Samsung Fridge RS2545SH stopped cooling. The fridge section is about 50/55 and freezer is around 45. It wont go below. At one point, there was rumbling rattling sound from the compressor. Icemaker also stopped woprking.
Hey how yo doing? on most refriderator there are two important parts to keeping freezer from freezing over, they are the bimetal thermostat and ice pipe heater. The bimetal therostat is a preset thermostat that ranges from 54degrees farenheit to about 60, when the coils (inside the freezer compartment behind the back panel) reach the preset temp. it closes a circuit and send electricity to the ice pipe heater, to warm the freezer coils preventing from freezing over. if any one of those components fail, your freezer will continue to freeze solid until there is no more space for ice to build on coils decreasing air flow from the evaporator fan blowing air into your fridge.To test you will minor knowledge on using a multimeter.(REMEBER TO UNPLUG REFRIDGERATOR BEFORE SERVICING, IF YOU UNCOMFORTABLE WORKING ON APPLIANCE PLEASE CONTACT A PROFFESIONAL REPAIR SERVICE..) If you'd like to continue please respond.
GOOD LUCK, WORK SAFELY..
does the freezer side freeze up also? i suspect if unit uses electronic sensors probably the thermostat sensors in the refrigerator section is defective. possibly there can be a thermostat board also you probably have to check diagrams.
What happens is the defrost is controlled electronically from a circuit board, when this goes bad, the freezer quits defrosting, and freezes the fans that circulate air through the fridge side of things.
To check this, unplug the entire fridge, leave the freezer open, wait for it to defrost a bit, if this causes the fridge to start cooling again when you plug it back in, then its the defrost. You should also see ice crystals on the back of the freezer just under the icemaker.
never buy a samsung appliance because you can not repair them. the company would like for you to buy a new one . my fridge the rs265labp freezes up in the fridge section and i have to take it apart once a month to defrost it. but i did find that if you keep a couple of boxes of baking soda in it and replace them often it helps to make the time between defrosting longer. hope this helps someone. i hope that samsung either goes out of business or straightens up
