If the Diagnostic Mode is entered with the Climate Control Drawer Lock enabled, it will be permanently enabled (hard-coded) on that Main Board upon exiting the Diagnostic Mode. If the Control Lock is accidentally left on when entering the Diagnostic Mode, the Main Power Control Board must be replaced to correct the condition.<br /> <br /> As a side note, after exiting the diagnostic mode, ALWAYS briefly unplug or turn off the breaker to remove the unit from power, then restore the power. Failure to cycle the power will result in NO COOL due to the main board not starting the compressor. http://repair2000.com/forum/viewtopic.php?p=8117#8117 Virtual Repairman Sat Apr 03, 2010 5:02 am http://repair2000.com/forum/viewtopic.php?p=8117#8117
