Electricity Supply anomoly


Recommended Posts

Hi,

Some time ago I noticed that the fridge in my grandfathers house would start up if I got up in the night and turned on a light switch and I have noticed it many times since then. I was wondering if anyone had an explanation for why this occurs. Same thing happens if I get up early in the morning to boil a jug. It wouldnt bother me so much but for the fact that it appears that the overload is directed to refridgeration devices meaning that if it is true there is a major electricty consumption efficiency gain possibility if the power companies improve their delivery system and this obviously then means that greenhouse emissions can easily be reduced by resolving that simple problem. On the basis that my theory on why it happens is correct all each government needs to do is to ensure that the electricity companies comply with a delivery efficiency guideline. Any thoughts ?

the fridge may use a relay switch with the thermostat to deliver the juice to the compressor via a separate circuit. switching on another load on the same circuit as the fridge may momentarily drop the current in the relay coil and the spring tension then pops the switch on. :eek2: that's all i got. :turtle:

I think Turtle is right on the monies with this one, try plugging the fridge into a different plug{circuit} (an extension cord might be needed) and see if this makes a deference.

does the fridge lght turn on when you open the door if the light is off? You plug could be linked to that switch.

 

:shrug: clap didn't say anything about the refrigerator's light. :tree: Since the refrigerator has only a single cord, then a single circuit is feeding the compressor motor, the relay/thermostat, and the light inside. Now since the relay is what would trip when a surge on the supply circuit occurs, and since the relay controls the compressor motor and not the light inside the refrigerator, then the light in the refrigerator has no bearing on the original problem. :o

 

Since you brought it up though, I wonder if the light in the refrigerator goes out when the refrigerator door is closed? :idea: :turtle:
