MT Vernon Non AE/E2 Wiring

[zz99mz]

Hello all

I have been working on my parents pellet stove since it's burned up 3 controllers and they're now on their 4th. I come from an engineering/manufacturing background, so this is a pretty easy task. What isn't easy is the lack of information on these units. This unit had been serviced multiple times by other technicians and the wiring was incorrect(yes, I'm aware of the wiring mistake on the fuse leg with the neutral and it's already been corrected). What I need is another member with a functioning stove to post photos of their wiring so I can compare it, or if someone knows the wiring from experience let me know if this is done correctly!

Thanks!

From what I can see on my phone, snap disks #1 and #2 wires are reversed. Purple wires go on snap disk #1 (outside snap disk) convection blower

Thank you! Sorry I fell ill and am just getting around to the stove. I get 3 flashes on the board, which indicates a thermocouple issue. I just had replaced the board and thermocouple with brand new parts. Does it need an additional ground? Or just a doa coupler?
