Kill-a-Watt meter dies

I bought it at Newegg last February (i.e. about 9 months ago), and after playing with it a bit, plugged it into a power strip and plugged my computer system's surge protector into the Kill-a-Watt. So, that's where it's been since March, I guess. When the computer was on, the juice pulled through the Kill-a-Watt averaged 180 watts. Average at least once a day, I turned the surge suppressor off, making the juice Zero. A few days ago I glanced at it and the LCD was blank (while the computer was on). Usually it read somewhere between 120 watts and maybe as high as 225 watts. I doubt there was ever a draw over 350 watts or even 300 watts.

I figure my mistake was leaving this thing working the whole time. My computer's not on all the time, at most 20% of the time, but maybe this thing isn't designed to last if it's used a lot.

I found the instructions last night which included the warranty info: 6 months but in some states there can be no time limitation (I'm in CA), call the company for details (N.Y. number). The instructions say "To reset, remove power from unit momentarily." This morning I tested it some more, still nothing on the LCD. There are 3 very small screws holding the back on, and I opened it up, and saw no fuse. Drat. I looked over the internals -- a couple of circuit boards, various electronic components including capacitors (they look OK), IC's, etc. I decided to put it back together and call the company. After putting the screws back in I test it again and now it's evidently working! When opening it up, I didn't disconnect anything. That should have had absolutely no effect. Weird.

Yeah, that was my thought, like I said in the OP. The instructions don't say anything like that. I have a mind to call them and have a chat, hopefully with a technician.

Yeah, sarcasm. Well, if you owned one, you'd probably be interested. Nobody made you read the OP.

With the OP+first reply being Arcadio, I was unable to look away. Apparently my boss is upset with me now, because I ignored her while I was so engrossed in this thread.

I don't think it's worth all the trouble. Aren't they like $12?

More like $30 at Harbor Freight, but I got mine for more like $25 from Newegg.

I don't think it's working right. I plugged a wall wart into it and it said 0 watts. Plugged my laptop's AC adaptor in and it said 2 watts and a couple of seconds later reverted to 0 watts. :confused:

Sounds like you got a borked one.

I left one plugged in with a 1000W space heater for about 6mo once.

It melted the plastic around the prongs.. lol

It might be functioning. I may have never tested it with small loads, e.g. a wall wart with no load. I have a system I made years ago using a modified extension cord with banana plugs plugged into a digital multi-meter. That gives very accurate readings for watts. The Kill-a-Watt seems to be pretty OK for ~20 watt range (my laptop off adapter), but reads zero with a ~2 watt draw (wall wart).
