Harman Invincible RS -3 flashes on status light

[Invincible RS]

I purchased a used Harman Invincible RS, it will start up and runs fine for 15 minutes before it has the 3 flashes on the status light, reset it a few times. I replaced the ESP, with another black wire one (dip switch 5 is off) and it still has the 3 flashes... I then replaced the room sensor as well, and still the 3 flashes... It appears the control board has been replaced before, part #3-20-06142C is now in it. Any thoughts, on what to try before I purchase a new control board? Is there any special settings on the dip switches, like #7 & 8 that I read control temp. Parameters for the ESP? Thanks for any help.....

Sounds like it needs a manual reset
Unplug the stove wait 5 min and try again
Do you have a manual for the stove if not
you may find one on line

I did do a few manual resets as stated, but didn't work.

Well took a chance and broke down and bought a control board, and that fixed it!
