Icemaker Not Making Ice

Before diagnosing any appliance repairs, disconnect your appliance from the electric, gas and water supply before you begin any work! Wear gloves! The insides of appliances can be sharp! 

First, check the freezer’s temperature. In order for the icemaker to produce ice efficiently, the temperature must be between 0-8 ºF.

If your icemaker is newly installed, it will take about 24 hours for the temperature to adjust to around 15 ºF before it can begin producing ice.

If the temperature is below 10 ºF, make sure that the feeler arm, which can either plastic or metal, is in the “down” position to ensure icemaker is not at fully capacity and can continue producing ice.

If the temperature inside your freezer is above freezing, check the evaporator coils behind the freezer panel for ice accumulation.  If you find that the evaporator coils are covered in ice, then there might be something wrong with the refrigerator freezer’s defrost system. You will have to troubleshoot and fix it before it's cold enough for your icemaker to make ice.

Next, check that the water supply line that connects from the back of the refrigerator to the home’s water supply. Inspect this part for any leaks of loose connections.  

If there is not a leak in the water supply line, there may be low water pressure caused by clogs in the line. You can check the water supply line by removing it and blowing air through to clear any potential clogs. 

You can check the water pressure by shutting off the water supply and disconnecting the line. Place the line in a bucket and turn the water supply back on to observe the flow of water. If there is a sufficient flow of water through the supply line, then you have a defective water inlet valve and it will need to be replaced.

How to Test and Replace a Water Inlet Valve.

The water inlet valve is an electro-mechanical valve with solenoids that open and releases water to either the icemaker or dispenser. If one of the solenoids is defective it might not let water flow to the icemaker unit. You can test the water inlet valve for continuity using a multi-meter. If defective, the water inlet valve might not be letting water flow to the icemaker. If so, replace it. Shop for Water Inlet Valves 

Next, check the water filter. Water filters can become blocked and need to be replaced. You should replace your water filter every six months or sooner, according to use.
