Hoping you(s) can give me some direction and input. The engine has 4 cylinder head temperature (CHT) sensors and 4 exhaust gas temperature...

    Kenmore range timer board burnt resistor

    Thanks Ramondo (interesting read) and rjenkiinsgb I guess I scanned that list a little too quickly. After I posted this question, I kept looking at images for that board and found some that looked like R1 was a 220 ohm ( 1 looked 270 and one other looked very different. ) My friend who owns it...

    Kenmore range timer board burnt resistor

    Hello all I have a timer board from a Kenmore range model 970-687632. On the timer board, R1 is burnt beyond recognition. The board number is 3164627 Revision G. Anyone familiar with this repair or have access to schematics? It is a common problem apparently. Just looking for the value of the...

    Well, this thread dates back to October and I still have not received my order from the ebay seller. Projected delivery was into January...it was so far away, I did not even pay attention but here it is March and still, nothing. I contacted them and their answer was that they mailed it to the...

    Getting old and out of touch

    Thanks everyone. Since I have the ebay ones ordered, I will wait to see what happens. It is just the variable side of my multi output power supply. I can get by with the fixed 5 and 12 v outputs. Regards Shawn

    Getting old and out of touch

    Thanks KISS I am in Canada and international shiipping rates would be a lot. If COVID had not caused the borders to be closed, we would normally drive 30 minutes to Minnesota and bring it in, saving customs fees. But, we cannot even cross the border now. Nice to see reasonable prices for those...

    Getting old and out of touch

    You mean LM338? $ 121 ...ouch https://www.digikey.ca/en/products/detail/texas-instruments/LM338K-STEEL/6224 I might have to rework the installation, going with a TO220 case component and a bypass transistor. Something I have thought of for other projects but never actually done. Thanks Shawn

    Getting old and out of touch

    Hi All I graduated from college in 1984. I worked for several years in electronics but then diverted to unrelated. I continued to dabble....but knew I was losing ground quickly as electronics advanced. Today, I was on the bench and the power supply I built several years ago, just a common...

    Electric motor help

    Would I be able to get the same kind of speed control and range if I went to a 24 vdc motor? I realize that I will need to rework the circuit and power supply. It is just that they are so much more common.
