Ice maker question. A while back, my icemaker went nuts and made way too much ice and then quit completely. From internet searches and browsing your site, I determined that the sensor boards were faulty so I replaced them and also the metal ice tray as the slick coating was trashed. Now I have what appears to be accurate LED operation from the board (which it was not before) but icemaker will not cycle and fill. I have attempted to run the troubleshooting diagnostics from the documentation supplied with the sensor kit but cannot get the main unit to fill with water or enter "harvest mode" and cycle the tray actuators. I cannot see how both the motor unit and sensor kit could fail at the same time. Could a bad motor cause damage to the sensors (or vice versa)?
ANSWER Hello Steve,
It is possible that the icemaker motor or the emitter board could cause the other to fail. The way to put into a test mode. Take the front cover off of the icemaker. Put a jumper wire between t and h. Remove power to refrigerator for 30 seconds then reapply power. The jumping from t to h will allow the unit to bypass the thermostat and will allow to cycle. Check for water when fingers get to the 11:30 positon. If no water then check the fill tube to ensure that it is not frozen. If this is ok then cycle again and check for power to water valve when the icemaker calls for water. There should be 120 vac to the water valve when it calls for water. 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
