Most water and ice dispensing systems will allow you to choose chilled water, cubed ice, and crushed ice. But it’s important to know how the Refrigerator Water Dispensers operate as well as potential problems you can encounter. Now first we will know how the Refrigerator Water Dispensers actually work, first The home’s water supply line connects to the refrigerator’s main water inlet valve, which requires water pressure between 20 and 120 pounds per square inch to operate properly.
When you press the water dispensing lever or button, a switch or switch allows voltage to travel to the dispenser solenoid, and the water filters solenoid if applicable to the model,
the filter solenoid may be on the main inlet valve or on a secondary valve. The solenoids open the valve system, allowing water to flow through the filter, if applicable, into the water tank and through tubing to the dispenser spout.
Common problems that can occur with the Refrigerator Water Dispensers include
- water dispensing too slowly,
- the water not shutting off properly,
- or the water not dispensing at all.
If the water dispenses too slowly or won’t shut off properly. The cause could be insufficient water pressure, a restricted filter, or a defective water inlet valve.
If the water doesn’t dispense at all, the cause could be a defective inlet valve or water dispenser switch, you can test both the valve and switch to determine if the components are functioning properly.
Refrigerator Dispenser Checked Work
The ice produced by the ice maker collects in the ice dispensing bucket when you select cubed ice and press the dispenser lever or button, a switch or switches are actuated, allowing voltage to travel to a motor that drives the ice auger and to a solenoid which waits for a rod that opens a door at the front of the Refrigerator Water Dispensers bucket. As the auger rotates, it pushes the ice out of the dispensing bucket and down the chute at the front of the dispenser.
When you select Crushed Ice, the door at the front of the dispensing bucket remains closed. This diverts the ice cubes through a crushing blade system before the ice is dispensed down the chute on some models, the AGA will rotate in the opposite direction to push the ice cubes through a crushing blade system. You should inspect the dispenser, lever, button and shoot the door to determine.
if any parts have failed. You can also inspect the dispensing bucket and or assembly for worn or damaged drive components. The components appear undamaged, hold the door switch while pressing the dispenser lever or button and observe whether or not the or-go motor coupler is rotating. If the coupler is not rotating, you should test both the auger switch and the door switch for continuity to determine if there is a continuous electrical path present in the parts.
Fridge Dispenser Not Working — Refrigerator Troubleshooting
If your refrigerator, ice, or water dispenser is not working, here are the top seven and most probable causes.
Faulty Dispenser Switch
The switch actuated by the dispenser level could be faulty. Depending on the model, you may be able to use a multimeter to test the switch for continuity with a continuous electrical path present in the switch.
Defective dispenser control button
If the dispenser functions are not working properly, the control board may become deactive. While the board cannot easily test it, you can inspect it for signs of burning or shorted-out components.
Malfunctioning door switch
When the refrigerator door is opened, the door switch turns off the water and ice dispensers. A malfunctioning door switch may prevent the dispenser from operating even when the door is closed. As with the dispenser switch, Because you can use a multimeter to test the door switch for continuity if you want to know the switch was failed electrically.
Faulty water inlet valve
the refrigerators’ water Inlet valve opens to allow water to travel to the water dispenser and into the ice maker. The valve can fail mechanically and electrically. The Mineral deposits could cause a mechanical failure. You will prevent the valve from opening, If this happens, just replace the valve with the new one. To determine if the Inlet valve has failed electrically, use a multimeter to test the valve solenoid coils for continuity. The Inlet valve should be replaced if one or more coils fail to test positive for continuity.
Low Water Pressure
The water inlet valve requires at least 20 water pressure per square inch. To help determine this, They shut off the water supply and disconnect. The supplies line from the mud valve and hold the line over a bucket. Re-connect the water supply and check if there is any water coming out of the line. A low flow is a sign of a problem in the water supply valve or water line.
Frozen Water Supply Tube
A frozen water supply tube leading to the ice maker tray, or the water dispenser can also impede dispenser functions. The supply can be cleaned and heating with hair. A frozen supply tube usually means that there is insufficient water pressure or a defective Inlet.
A defective main control board
Although it’s not a common problem, a defective main control board could result in the ice or water dispenser not working. You can inspect the mainboard for signs of burning or a shorted-out component and replace it with a new one, provided all of the other dispensers parts are working properly.
