HAVE A NEW 2454  DOMATIC 3 WAY REFRIGERATOR THAT WAS INSTALLED BY AN AUTHORIZED AIRSTREAM DEALER. WORKED FINE UNTIL SAT WHEN I UNPLUGED TRAILER FROM 30 AMP POWER WITH REFRIGERATOR ON AC POWER. WHEN PLUGGED BACK INTO AC POWER , REFRIGERATOR  HAD CHECK LIGHT ON AND NOT COOLING. I SHUT REFRIGERATOR OFF AND THEN BACK ON. WILL RUN ON DC AND GAS BUT WILL NOT SWITCH TO AC, EVEN USING AUTO MODE. CHECKED ALL CIRCUIT BREAKERS AND SWITCHES. CHECKED PLUG IN RECEPTICLE  , ALL OK. PULLED CONTROL BOARD COVER AND CHECKED 3AMP AND 5 AMP FUSE .STILL NO AC OPERATION. BOARD AND HEATERS BRAND NEW. I SAW  SOMEWHERE THAT THERE IS A FUSEALE LINK WIRE TO THE HEATER. PLEASE ADVISE .

HOW DO YOU REMOVE THE BLACK COVER FROM THE FUSE PANEL. I REMOVED THE TOP CENTER SCREW AND I DONT SEE ANY OTHER SCREWS. DOES THE LOWER COVER SLIDE OR PULL OFF?
