control lock is on cannot get off

HI. Is the control lock button not working? To lock and unlock the control you press and hold the end of cycle signal button for 3 seconds. The control lock light is on the left side of the control to indicate when it is locked and unlocked. Attached is the tech sheet for your unit. You can also try to put it into diagnostic mode, which may not work if the control is locked. What did you do to reset the unit? TO give it a good reset unplug the unit and take a screw driver and place it across the units plug terminals so that the metal makes connection between them. Now press and hold the start button and control on buttons for 10 secs. This will drain any memory or capacitance from the system. If the button is not working to unlock the control then you would need a new user interface. p# 8558756
