Samsung fridge RS2545SH every 7 days freezes fridge coil.
I have a Samsung RS2545SH 2 Years old. The one w/the twin digital display in front. It keeps freezing up the refrigerator coil every 7 days or so. I have to go in and manually defrost w/ a blow dryer. Can you please advise me on any fix? Thanks in advance.
Re: Samsung fridge RS2545SH every 7 days freezes fridge...
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..

defrost problem, check defrost thermostat on evap coil by removing the back panel in freezer for continuity, if open, replace. check heater in the same fasion, if open, replace. if both are ok, replace defrost timer, or adaptive defrost control.
I had a similar problem where my evaporator coil was freezing into a block of ice, which caused my fridge to warm up due to a lack of air flow. I fixed this by doing a few things. I replaced the circuit board ($100) which was easy to do. Unfortunately, this didn't fix my problem so I took the inner fridge cover off to view the evaporator/heater coil assembly. I checked my thermo fuse and found it to be open (failed). I ordered the thermo fuse and the thermistor and replaced them both. I then plugged the fridge back up and put a regular thermometer inside the fridge to get an accurate reading of inside temp. A few days now and everything looks good. The board, fuse, and thermistor were all pretty easy to replace.
I've had my Samsung RS267 LASH side by side for almost 2 years now and the coils froze recently. The temperatures displayed - relating to the refirgerator side - bounce around when the coils freeze. My freezer thank goodness is still working properly. The repairman indicated that the heating element for the refrigerator coils was bad. Unfortunately he had to order the whole unit (coils, heating element, etc.) since he couldn't replace just the one part. Samsung takes their time sending the parts - we've been waiting for 10 days now. The Samsung warranty covers the compressor, evaporator, condensor, drier and connecting tube for 5 years parts and labor so we should becovered. You might be covered as well - depending on when you purchased your refrigerator. I did purchase a separate extended warranty from Lowes when I bought the refrigerator and I'm glad I did. My extended warranty included $250 in food spoilage covering our food loss due to the breakdown. Hope this helps......
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.
its a heater cycle problem..the defroster is not working properly. its building up ice in the evaporator that touches the evaporator fan that makes that loud noise but stops when you open a door. it could be either a bad heater, a bad thermo disc or a bad timer.hope i was able to help
