My fridge was damage by high voltage of electricity is doesn't switch on at all ,Model sv2118si 660 litre Sumsung
When you say that your fridge/ white goods appliance was damaged by high voltage, we need to exactly what the voltage source was that did the deed.
If you are talking about a bigger voltage input source, from the mains suupply, then it is likely you would have had a fuse within the plug that would have blown. This should be the first thing you will check regardless of the voltage.
If however, you are telling me that your house took an in-direct or worse still a direct whack from a lightning strike, then my dear friend you have quite possibly a totally deceased appliance. For a start, such a strike could melt your plug and possibly socket. The fuse inside the plug wouldnt be a relevant factor here; because if the lightning made it from the sky to the ground, I am sure it can cross a 40mm gap within a plug. Then the lightning surge would simply travel up the power cord, knock out your gas pump, stepdown transformer and any lights or motors within the appliance. The cost of changing every part here is not worth it. You would be better off claiming on insurance or simply buying new.
there are a few ways you can investigate what has caused this, and possibly cure the fault, unless it is a lightning strike of course that is responsibe.
The first thing to do here is dismantle the mains electricity plug that is attached to the fridge. Check the small fuse inside this to see if it is functioning. You can do this in many ways. The best I find is to get a multimeter or the appropriate tester and perform a continuity test. See this link below
If the fuse is broken, then change it and repeat the test; YOU MUST replace the fuse with what the original one from the manufacturer was.
If the fuse is working, then your fault is elsewhere and you will need to perform the above tests on various components relevant to your fridge.
The worst case scenarioo is the lightning strike; and in order to identify this, you will need to do one or two simple things.
Firstly, head to your main consumer unit (fusebox) and check that all of the fuses are in the "closed" or "on" position. Open fuses indicate a power surge or a short circuuit somewhere on your supply, but relevant to your fridge. RCD circuit breakers all narrow down the searching to one localised area. You should also do this test for identification of original fault.. The same for when you as above check your main fuses.
If the fuses on the consumer unit are "open", then either replace them if you have to, or you simply either push them back in or move them to the "closed" position. Also check that the consumer unit is not damaged in any way, as you would expect from having too much electricity put through it. Fire damage, warping, blackening, discoluration, bent or broken components are all good indicators of this.
Another test you may have to do, is simply look around your house. Has anything else been effected. If it has, then it is likely that it was a lightning strike or something equally as damaging, if no, then it could simply have been a power surge that only really effected your fridge. Even so, is any of your other electronic and white goods items behaving oddly? TV menu keeps appearing or going into standby? Is the lights on your DVD player behaving erratic or does discs keep being ejected at atrange times? What about your computer or laptop; do these strangely start playing up? If so, then either the lightning strike is to blame or you have had a powersurge.
Once you have done theseinvestigations please let me know the outcome and if it is negative, Iwill gladly advise you further.
I look forward to hearing from you soon and hopethis is the fixya for you;
