SGP/MFRSR/E38 - Heater controller failure

The heater board failed on 20120101 @ 0200 UTC.  There were very slight hints of the 
impending failure the prior month, but the mentor elected not to include those days in this 
DQR as data should not have been affected.  Maintenance on 20120124 resolved the problem by 
replacing the heater board.
