it beeps differently than before. the display lights up but there are dashes instead of zeros. i am unable to program anything and there are no other indicators lit on the display. i've unplugged/replugged, hit the reset button and no dice. any ideas?

under the plastic cover is the motor and wires. unplug the plug with 9 wires. colors are red yellow orange green grey white etc... on the front right side with the power on. unplug and plug it back in and it should work.
