Can an electrical outlet be "weak"?

Our 11 year old refrigerator stopped getting cold enough (42 to 48 degrees). It's done this before and we've replaced parts. This time I decided enough and replaced the unit. Now this new LG refrigerator is doing the same thing. I've had a tech come out and they replaced the board with all the pertinent parts and it still isn't getting colder. But I've plugged in our old unit in the garage, where it is cooler, and now it's at the correct temp. Is it possible that it can be something to do with the electrical outlet? Wouldn't the service guy have had something to test that?

Is there any point to using the 'storage' part of storage heaters if you don't have an offpeak tariff?

I've just moved into a new place that only has storage heaters for heat. However, the tariff on the electricity does not have an offpeak component. Given this, I was wondering if there's any point in using the storage aspect of it (if its more efficient, for example) than just using the 'boost' function that gives you heat instantaneously.

what just went ka-bing on my stove?

What just went ka-bing on my stove? I was just cooking pancakes on the stove. The oven was also on at 300 degrees, to keep the pancakes warm as they came off the griddle. The overhead bonnet light was on as well. Suddenly there was a strange flash. It happened in such a fraction of a second that I cannot tell you where it was from. It was like a tiny red sparking mini-explosion -- somewhere! I turned off the stove -- and could NOT turn off the light on the bonnet! [more inside]

New Nervous Tick

Four days ago there was a storm. Standing ankle deep in water which had flooded up to my front door step, I stuck my metal key into my apparently 100% metal door and ended up sort of electrocuting myself, feeling a tingle and shock going up my arm. Since then I've had this weird tingling sensation in my right hand and arm up to my elbow... just now I tried to hold up a can of soda my fingers and hand tremble. Now what? [more inside]
