Connector Cleaning / Checking Unplug the unit Open it up Remove the ribbon cable from the keypad to the control board at the control board. Clean the edge connector. If it is the type where there is not a connector just the insulation is removed, it can be cleaned with a pencil eraser. Do not use an ink eraser as it is too abrasive. Check the tracks in the ribbon cable for hairline cracks. A magnifying glass helps here. Would not hurt to clean the connector on the board. Use electronics contact cleaner or isopropyl alcohol and a tooth brush. Be gentle and do not reconnect till all the solvent evaporates. Reconnect everything and give it a try. |

The directions were consise and made me able to complete the process w/o damaging the unit. This was, however, not the problem as it turned out (it's never this easy for me!) but I now have a clean connector ribbon! Thank you very much for your time.
