I have a 2100H that had a similar problem.  There is a transistor on the
bottom side of the board near the power module.  Two leads are soldered to
the board.  The tab is soldered to the circuit board.  The solder connection
looked OK, but once I resoldered it, no more intermittent problems.  The
heat gun and freeze mist program narrowed the search to that component......
