I have learned so much from your videos, have always felt guilty receiving so much knowledge yet unable to afford the price of admission. Untill now. Living in low income housing waiting for the va to fuse my ankles. Boo hoo. You kick ass. You have kept me motivated and kept me going. I have hunted down a ton of kit on the cheap thanks to you.

@chrisjones87414 years ago I got a big fancy samsung microwave a little while back for free because it was broken. Lights were on but nobody was home, the high voltage fuse was blown when i poked around just a little, it dawned on me that there was probably a relay welded shut. Then today when i saw this video pop up in youtube, i realized why i figured out the shorted relay quickly. I had watched this video before and its almost the same problem!
thanks so much mr. Carlson! I have the replacement relays but now im also thinking about putting in your zero crossing circuit instead for longevity. ...Expand

@yambo595 years ago After she passed and we inherited her stuff my aunts old schoolside by side frigidaire from the 70' s wasnt built with all this failure prone b. S. And it lasted 40+ years without a single major repair, just coil cleanings and a door gasket. Same story with her ' 70' s era ge washer and dryer, they lasted 40 odd years with one new hot/cold valve and a new heating element and belt in the dryer - the washer was one of the most durable ever made, the ge filterflo, had the lint filter pan on top of the agitator. I was shocked when i went to buy a new washer and saw how badly they had been cheapened. I fixed the heating element in the dryer, installed a new belt just because and bought me a commercial duty speed queen washer thats old school on the inside and built really well-and it has an agitator- that thing washes clothes clean like an old maytag and no stupid error codes or flying apart like the samsungs etc. Have been doing. Nothing is built to last anymore, too much unnecessary electronics and too many gadgets and built to fail, lucky if you get five years out of many new appliances without trouble,. ...Expand 136

@someguy26372 years ago Paul,
another greatvideo! I enjoy the modernvideos as much as the antique ones you share. Unfortunately, repair techs are board replacers and can' t take things to the component level as you do. I had a similar problem, caused at times when i experienced an ac glitch at the line voltage level whenever the utility company performed switching. Fyi, i agree with your comment regarding digi-key.

@Blasserman5 years ago I have to say that this was the first time i witnessed mr. C doing what we used to call using theapproach toa board. of what normally might fail, along with some previous experience with the same board is crucial to this approach. It' s been years since i was fixing stuff in a lab, but i do rememberall of the time with mostly good results. The reason was the older equipment we worked on had components that failed often enough to make it worth while to say, just replace them all before i even plug in it to test it. We had lots of pressure in our lab to get parts turned around, and at the end of the month we would end up actually having to trouble-shoot the ' dogs' that didn' t respond to the shotgunning approach. ...Expand
