    Fridge Question

    I was checking out our recently plugged in fridge to see if it has a ground wire. It does not. I will add one. It has a lug marked "earth", but nothing connected....

    While in back I noticed a small white plastic box down at the lower left side of the box. This houses various electronics and what looks like a timer. The time has a shaft leading out of the box, but whatever was on it has broken off. Maybe some sort of knob or indicator? No mention of it in the user manual and when we called Samsung to ask we were put on hold for 15 minutes and then told, "It doesn't do anything." Hmmmm.

    Any ideas? Is it perhaps a timer for the defrost and anti-condensation cycles?

    TIA

    All the fridges we've had have not had a ground. Not sure why, cos I would have thought it was one of the things that would need one - toaster, microwave, computer etc always come with 3 pins, but TV, fridge always with 2.

    Infact we once had a problem with shocks from a fridge and an electrician grounded it individually.

    If you are talking about Samsung fridges, the ones that they sell in Thailand, no ground but the ones that they make to sell in Europe ermm... yes, they make them with ground.

    So yes, you are right. It's a timer for the defrost and anti-condensation cycles.

    What? No auto defrost? Last time I defrosted a fridge was 1966. Oh, wait, 1999, when I had a one-door unit with one of those mini clear-plastic-door freezers that the geckos always crawled into and that frosted up like Santa's pee remains every week. Made good snowballs tho.
    Never had grounding for appliances in Thailand. Electricians didn't know what is was.

    ^So why do toasters and microwaves come with a ground???

    BTW, it's Samsung who should give a shit, even if it is within the law they shouldn't sell appliances that could cause harm.

    So either a fridge doesn't really need a ground or all the companies are negligent.

    Ever tried to get electricians to install 3 core wire in a house?
    Never heard of it most of them.
    I had it installed and when they fitted the wall sockets they were two pin, I said no, I want 3-pin sockets for the earth.
    Oh we wondered what that was for was the reply.
    Bad enough that they keep crossing over the neutral and active.
    If you have a flouro that seems to stay partially on for a while cross the wires over.
    Sharon is right some models will have a rehostat to time defrosts.
    They probably set it to maximum and removed the knob.
    Always best to earth these things, even a wire from the chassis to the wall(concrete of course) will do.

    Refrigerators, freezers, air conditioners, clothes washing/drying equipment, motors, and tools used in wet and conductive locations are some examples of equipment that must be grounded. Refer to 29 CFR 1910.304 (f) for specific grounding requirements.

    Well, the new house I'm moving in to has three prong outlets, but in the course of construction I discovered that they don't bring the grounding wire back to the breaker box, nor do the houses have a grounding rod with a connection to the breaker box. I had them install a grounding rod and run the ground for every circuit back to the box. I will definitely ground the fridge...

    None of our appliances came with a ground pin. That's toaster, blender, microwave, hot water pot and washing machine. I added one to the washer, but not any of the others.

    I suppose it would be nice to have an earth connection

    Does the circuit breaker (not the consumer unit ones) that you have to fit not do a good enough job?

    If there are any problems, mine just cuts off the current

    CCt Breakers will not stop an appliance from becoming charged.
    They work when neutral and active become shorted, or over load in amps rated for the CCt Bkr.
    Best to earth, particularly hand operated appliances, like an iron, toaster or microwave.

    Anything I have bought in Thailand had no grounding pin installed in the plug, did have a hole to put a pin in tho, but can not buy the pins anywhere, so I made them out of a piece of brass rod, but in any house I ever lived in here had no 3rd wire plug ins either, even the plug strips on a cord that you but that have 3 holed did not have 3 wire cords on then and the 3rd hole in the plugs were not hooked to anything,,so no 3 prong plug,,no grounded plugs.
    When we had the house built I insisted on 3 wire service installed and had a time buying 3 wire core romax and did find a long copper grounding rod, and then had to fight the electrician to do a proper instillation.

    any electrical item with a metal case / exposed metal should be earthed. If a fault in the item causes a live conductor to contact the metal case you want it to cause a fault current to run through the earth wire and that high current should trip the breaker / blow the fuse. if the metal case is not earthed the live conductor will just make the metal case live which can cause electric shock / electrocution to the next person/animal to touch it ( assuming another part of the person is earthed - highly likely with water involved )



    your earth stake should be solid copper , not just a copper plating.

    Make sure that all three wires go back to the breaker. The jerks here tried to pull this one on me:


    They were quite embarrassed when I showed them that the grounding wire only went about 30 cm into the conduit. After that they quite willingly ripped everything out and did it over. It's now almost OK.

    with a multimeter and a length of wire you should be able to check that all the earths go back to an earth bar in the switchboard

    I've got the schematic:



    I'm guessing that the device I'm wondering about is the one labeled as a timer: the box on the left with the C(3) above it.
