Questions & Answers

For Frigidaire Dishwasher Main Control Board (Part Number: OEM18981690)

1 Answer

Hello Dick, If the unit is running into the cycle that long, I would suspect a water heating issue. Pull the tech sheet from behind the kick panel and check the components of the heating cycle and you will most likely locate the issue. If you require further assistance, please post the model number next time so we can concentrate on your specific model.

Hi. Look behind the lower kick plate or behind the control panel to find the tech. sheet that shows how to put it in a diagnostic mode. This will allow you to see which cicuit needs attention. Use a volt/ohm meter part # MA-DM1 to assist you in your diagnostics. Let us know what parts we can assist you in getting. Thank You.

Hello Rich, The ER error code is defined in the service manual as follows: When the control verifies that any of the pads on the membrane switch has been closed for one minute the failure will appear in the display. This will be the console assembly 154791806 causing the code.

Hello. You will need to remove the inner door liner and then remove the cover off the old control board. Make sure the power is disconnected before doing this. Then remove the wires and the old baord from the unit. Install the new board 5304514670 in reverse order.

Pam, You're on track, The issue is most likely a keypad/control panel issue 154639207, based on your post description. Since certain cycles can be selected and operate, it's not likely a control board issue. Thanks

Hello Peanut, I would probably check the harness with my test meter TJMA-DMT3 for proper continuity, (no resistance). If the harness is good, since you replaced the dispenser already, the control will have to be the problem. Of course, you could try the dispenser assembly again since you still have part warranty on it.

Hello Peanut. Try removing the ribbon cable from the control board and cleaning the ribbon cable with a pencil eraser. Then re-install the ribbon cable into the control board making sure it is good and dry. If so, and the problem continues, it sounds like the control panel 154639208 is bad and will need to be replaced on the unit.

Hello Ran. You will need to test and see if there is power coming to the control board. If so, and nothing works on the unit, you will need to replace the board 5304514670 in the unit. If the lights work, but the unit won't start, you will need to test the door switches and see if they are good. If so, replace the control panel 154791803. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html
