The tray fills up with water and freezes but won’t dump ice into the bin. Model LFX28978ST/02. The unit adds more and more water to the tray that is already filled with ice, so water runs out the door, down the side, and puddles on the floor. When I push the reset button the tray does INDEED turn, so the motor works. If I melt the ice block with a hair dryer and remove it from the tray, the icemaker seems to work in that it fills the tray with the right amount of water, it freezes, and then I can dump the normal cubes into the bin manually, using the reset button. If I don’t dump the ice manually, though, it never gets dumped, more water keeps getting added to the tray, the tray fills up to overflowing with ice, and I get water on the floor again.
Icemaker Mold Thermostat If the ice maker is not working the icemaker mold thermostat might be defective. Inside the control module of the ice maker is a thermostat which monitors the temperature of the ice mold (ice tray). Once the mold reaches the proper temperature the ice maker starts a harvest cycle by ejecting the ice cubes and refilling with water. If the mold thermostat is defective the ice maker doesn’t advance. The thermostat can be checked for continuity. (See if it is closed). Replace it as needed.The freezer temp should be between 0-5 degrees for optimum performance. Icemaker Switch If the refrigerator ice maker is not working, check the icemaker switch. This switch frequently gets turned off by accident. If the switch is turned on but the ice maker still doesn’t work, check the switch for continuity with an Ohm meter. Replace as needed. Ice Level Control Board If the ice maker is not working the ice level control board might be defective. This refrigerator is equipped with an infrared light beam to detect the level of ice in the ice bucket. As the level of ice reaches the top, the beam is interrupted and the ice maker shuts off. As ice is used up and the level of ice drops below the beam, the ice maker starts up again. If the ice level control board fails, the ice maker will stop making ice. Door Switch If the refrigerator ice maker is not working, the door switch might be defective. When the freezer door is opened the freezer door switch does two things, it turns on the light in the freezer and turns off the ice maker and dispenser. If the door switch fails the dispenser will not turn on. The switch can be checked for continuity with an Ohm meter. If it doesn’t have continuity it should be replaced. Icemaker Module If the ice maker is not working the icemaker module at the front might be defective. The module has a motor that cycles the ice ejector arms around to push the ice cubes out when the ice maker thermostat closes. It also has contacts in it for the mold heater and water inlet valve. The motor or contacts of the module can fail. Usually there are test points in the module that a service person can use to determine if there is a problem with it or one of the related ice maker components.
So here’s my story - I don’t think it’s represented here. The icemaker has a sensor in it that it won’t dump unless the temp is below 9 degrees in the compartment. In my case it was 30, so cold enough to make ice but not cold enough to dump. That’s basically an early warning indicator that the temp differential is problematic - which is a compressor problem, ultimately, because it can’t keep pace. In my case the evaporator coil and the compressor have to be replaced - $1200 in parts for an $1800 machine.
I’d suggest that the bar that suppose to be in the down position is either in the up position or the switch in the back of the fridge is broke,look to c if there’s a way to get to the switch and put a tester on it and c if the tester light comes on when the bar is in the down position if not then it needs replaced. That would be the first thing to .
my ice maker makes crush ice, not block ice. i have noticed that the device that kicks out the ice works fine (rotating one direction) but will NOT kick out the ice (when rotating the other direction)
i have an lg lfx25974st fridge and having ice maker issues. it makes ice but wont dump the trays unless i push the button inside to drop them. Also the black rubber door that opens to drop ice will not close thus letting cold air out all the time
