Pete M Posted September 1, 2009 Share Posted September 1, 2009 No, not those ones. :D My microwave is on the fritz. Nothing works at all in it. Fuses are good and I've traced good 110 power to the low voltage transformer. But the transformer isn't giving me the proper readings. According to the "fix-it paper" found wedged inside the back casing, it should be 17 ohms on the primary and 0.5 ohms on the secondary. The primary is reading too low (13 I think it was). Problem is that the part no longer exists in the world. :fs1: So I figure I'll just wire in a generic version. But I've got no idea what voltage should be coming out of this thing. The papers don't say and it's been a decade since I've had an electrical course and can't remember if it's possible to determine the output voltage of a transformer from only the input voltage and the resistance. Anyone remember? :dunno: any other ideas? Link to comment Share on other sites More sharing options...
dasbulliwagen Posted September 1, 2009 Share Posted September 1, 2009 Go to Wal-Mart, spend $50 and buy a new one. By the time you invest parts and your time in this one, youll have spent more than the $50. Or go to your habitat for humanity re-store and buy a used one for 10-20 bucks.... or how about yard sales this weekend?? HUH? HUH??? :yes: :yes: :yes: Link to comment Share on other sites More sharing options...
Pete M Posted September 1, 2009 Author Share Posted September 1, 2009 It's dad's, not mine, and it was a pretty penny when he got it. I'd like to fix it for him. :popcorn: Link to comment Share on other sites More sharing options...

Automan2164 Posted September 1, 2009 Share Posted September 1, 2009 1.31 jiggawatts...... :D Jeff no no no, it was 1.21 jiggawatts, jeeze, you're gonna kill someone :rotf: And that wasn't correct either. It was supposed to be Gigawatts. Christopher Lloyd mispronounced it, and they kept it. And some vid: http://www.youtube.com/watch?v=bnqtXOi1iaY Add that to the bank of useless knowlege.

HOrnbrod Posted September 1, 2009 Share Posted September 1, 2009 Pete, a microwave that old ain't worth fixing. I still have the same GE model, introduced about 12 years ago. It's failed for different reasons over the years, and I replaced it three times now, same model but "improved" - four year lifespan average. Everytime it fails, I troubleshoot it, zero in on the bad part, and when I look for the part(s) I need, it costs nearly as much as I can replace the whole damn thing for (less than $100). And then you're not absolutely positive the new part will fix it. Not worth the hassle mate. The old m/w's are very power inefficient too. :cheers: Link to comment Share on other sites More sharing options...
