Jim for Model Number LG, LFX33975ST ICE MAKER NOT DUMPING ICE, UNLESS I HIT TEST BUTTON. FREEZER IS NOT KEEPING ICE CREAM FROZEN. HAS A FAULT CODE OF "F" UNDER REFRIGERATOR AND "DH" UNDER FREEZER ON THE FRONT OF FRIDGE CONTROL. THANKS
Answer Hello Jim. The DH error code means it is taking too long to try to defrost. Or the evaporator isn't rising to the temperature is supposed to reach. It sounds like you may have a defrost problem with the unit. Check and see if there is any frost build up on the evaporator coils in the freezer. If so, you will need to test the defrost heater and the defrost thermostat. They should read closed for continuity when cold. You can test this with a multi-meter TJMA-DMT3. I will include a link at the end to assist you how to use the multi-meter if needed. If both parts are good, you will need to replace the main control board. Once the problem is repaired, you will need to thaw out the ice on the coils before the unit will operate properly. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html Read More...
