This example of modern life and first-world problems (solved) is about as mundane and pointless as it gets.
We got a new LG refrigerator a few months ago, and the other night the ice and water dispenser on the front door did nothing when you put a glass against the switch paddle. Then, after what had seemed like forever (but was only about 3.5 seconds), the ice or water came out. Up till then it had responded instantly.
At first I thought that there was a problem with the door switch, since it won’t dispense when either of the doors is open. I tried pushing against them, which seemed to work. But then I realized that the delay had nothing to do with the door. Just wait and the ice or water came after a little more than three seconds, whether you pushed or not.
There are probably bigger issues somewhere in the world, but it was annoying, and I wasn’t looking forward to the time it would take to try and get warranty service on the thing.
Then I had a thought. I pulled the fridge out from the wall, unplugged it for a few seconds, then plugged it back in.
