hi again George i talked to mth yesterday about my z40-4000 transformer that i had talked to you about before . he suggested checking the potentiometer Originally Posted by GGG:s, he said they both have to be timed so they are both shut of at the time. I had already knew that, and it was not the problem, he said on power up the transformer checks to see that both controls are off or the red overload light will come on.That's not the problem, when you reset the processor board and make sure all connectors are on and plugged in tight sometimes it will come on and work, It will only work for a few minutes and then the same symptom happens again red light and locked up, will not work again until sits a while and board processor is reseated again!do you have any idea,s George? im wondering if there is a leaky capacitor braking down under voltage or possible has lost a lot of its uf hence it lets ac noise ripple into the electronic and causes a lockup of the transformer processor due to noise on the dc line! anyone,have any ideas, he said the board "processor brd is around $100.00 but i wanted the challenge of fixing the transformer myself.I use to repair anything in electronics when i worked for PSEG before i retired. even repaired XRAY machine and explosive bomb detectors.
would appreciate any help. sincerely thanks to all you great guys!
Alan
