Good stuff. This is also problem in venues othert than HVAC. For instance if you have a mid-90s GM S10, Blazer, Sonoma, etc and the winshield wipers quit working totally or intermittently, pull the circuit card and reflow the solder joints on the power connector. If the smart valve circuit cards are anything like the GM wiper motor circuit cards 100% of them will eventually fail this way. A bad design (or bad manufacturing run) can cause amazingly consistent (and confounding) failure modes.

There are seven parts to this You tube. Very short segments except for acutal dismantiling

I watched part 4 which is what you posted and then part 5 but am having trouble finding the next one if there is one. I want to see it fire up after the so called repair.

Help?

It gets fired up in part seven .

Just add a 7 to the written title. Use the seven to replace the four .


here it is for Doc

Thanks. I've replaced quite a few smart valves, not sure I would go through all the trouble to fix the board which indeed the trouble has always been with those main pins.

I guess good for him..?

No more like he should go to jail for reckless endangerment.
He voided every safety certification that valve had by making that repair.

I enjoyed how he went about ranting about "stupid this and retarded that" and "it's a conspiracy theory, we have to pay..!"

However good he must feel about himself, his arguments of "plumming" the valve elsewhere like in the corner or down below where the control board is were ridiculously amusing.

I was half way being sarcastic. often, a tooth pick will hold the molex connector in a straight enough alignment, that the valve works again.

Yeah. As a temporary fix. Even then the dang thing messes up after awhile.

That's exactly what had happened to the last two smart valves I came across, they had been bribed into place. The first one someone from my company had simply put a wood splint in to hold the plug at a certain angle and it held for one year. I went for the new call this season, removed the splint and it worked for one day.

I replaced that sm.

Other one had the plug forced into place by use of about 5 zip ties. Replaced that too.
