Here is the tech sheet for the unit http://www.servicematters.com/d...0Sheet%20-%208558722.pdfTry to get into the diagnostics. I would check the door switch just because the light works does not mean that the Normally Open contacts in the switch are closing. By looking at the tech sheet you should get a beep when the door is closed. Check that you have 120 volts at the board P1-2 to P1-5 |

If the control board is getting the correct power and the keypad checks out OK then the control board becomes the prime suspect especially if you get no beeps at all.
Unfortunately this is a crap shoot, I have never been able to find schematics of the boards so you cannot do any real on board troubleshooting. All you can do is check the board for obvious problems re: blown components.
So the troubleshooting technique becomes if everything else is OK it must be the control board. |
