If you have checked for ice in your water lines and made sure your Frigidaire ice maker shutoff arm is in the right position, there is another easy bit of troubleshooting you can try. Follow the water hose from the fridge to the sink area. The hose connects to a valve under the sink. This is called the supply valve. Check this valve to make sure you have enough water pressure. Open up the valve more. Ice maker parts usually work on a cycle. If enough water doesn't fill up your ice maker's mold before the cycle is complete, the result is very small cubes or none at all. Your Kitchenaid ice maker parts require that steady water pressure to work properly.
