The units suck and there is no support--1500 dollor unit --they are making money on parts

I had 4 plumbers come by with the same response--the whole unit has to be changed or the electronic component

The blower on our State Select model PR640N0VT also would not shut off. After attempting other solutions discussed on these forums we decided that, like others, our magnetic switch which relays the temp to the blower was likely stuck. We turned the unit off, unplugged the two cords (white and yellow) which connect the main unit to the blower, and sprayed duster into all the exposed plugs and crevasses we could find. After we turned the system back on the fan resumed operating normally. It wasn't the fact that we restarted the system because we had turned it off multiple times after the problem began to no avail. This post inspired us to try using the duster: (https://www.askmehelpdesk.com/plumbing/state-select-water-heater-33192.html)

Hey all - I have a State Select PR640NOVT having this same issue with the blower running constantly. I purchased a replacement gas valve controller second hand but found out it's not going to come with any wiring schematic. Would anyone be kind enough to scan theirs in if you've also purchased this replacement part? The Part number is State part number 9002355005
