In the last 4 days I have replaced two Honeywell SV9541 gas valves.
Both were less than 3 years old.
Both were under warranty, but not to me, so I charge a handling fee for
sending a guy to the suppliers to get it, returning to the suppliers
afterwards for the warranty paperwork, the initial call-out charge, and the
labour to install it (Homeowners take note. So much for saving a ton of
money by going with the cheapest bidder! )
Neither customer could get in contact with the installing company, but boy,
did they get a good deal at the time of installation! One customer had
rejected my price when bidding because I was $300 more expensive than the
guy he eventually went with! LOL.
Anyway, be prepared to change a lot of these new and "improved" smart
valves.
Thanks Honeywell !!

so what was the problem(s) with either or both? pin connectors?
specific brands of equipment? bad batch of gas valves?

In both cases, the valve wasn't sending 110 volts to the ventor motor.
Also ,the diagnostic light is steady on, which doesn't match any codes for
it. Normal operation is a green "heartbeat".
I suspect the causes for this will come to light eventually, but for now, I
suspect a faulty internal relay.
Diagnosing whether it's the valve or the board is real simple.
Unplug the three connectors on the valve, and plug them into a new valve,
and just let it hang there, then energize. The ventor should come with a
call for heat.
Bingo! Bad valve.

If its in a 90%er check for condensation. Cold air comes in top, hits
the hot burner, condensation occurs and drips on the gas valve.
Sometimes takes a year but finally shorts out the valve. Causes
erroneous code errors, erratic or no inducer operation.
Good ol Honeywell.

I think you may be on to it.
I saw some corrosion on the pins
