18V15 over temperature error

Hello,
'Bought two 18v15 and got them working using analog input mode.
Things were OK for a few days, then suddenly one of the units always gets an “over temperature” (the temp is always 148.6C)
error on power on and the motor won’t start. The error happens immediately on power up, even if the motor is not connected. Any idea what happened? Is there a component I can repace?

Thanks!

Hello.

I’m sorry you are having trouble with the Simple Motor Controller 18v15. Does the board actually feel hot? (Be careful not to burn yourself.) What VIN does the Simple Motor Control Center report, and is that correct?
