GE Touch Control Radiant Cooktop Hot Indicator light stays on

My hot indicator light will not go off on Left front burner. Took cooktop apart checked wiring, everything secure.
Ran Tech Mode, checked codes, and it indicated to replace the main logic board. Ordered part from GE, just received and changed out the main board, it still stays on?

Doe anybody know what else I can do. I called GE Parts and they do not have all of the codes. Displays F161 when I do a Tech Mode diagnostic test. In addition, LF! diaplays 0880 Celcius reading while all of the others show 26Celius in test mode.
Not sure what to do before returning the main logic board. (cost me $350.00! But GE has a 30 day return policy.
