Hi there,

Have you solved your issue? I'm going to throw in a few suggestions that hopefully help you to figure out how to solve it:

- Check out if you are getting any voltage where you would install control board

- Reach out to manufacturer and ask the same question

- Checkout troubleshooting section of equipment manual

- Do you have any maintenance records that could help you figure out it that happened before?

- Is there anyone out there who could help you out? (contractor, friend, etc)

- Any warranty you could claim?

Cheers
