Norcold Ice Maker no ice

The only problems we have had with our ice maker, when it would not make or dump the ice was freeze up in the valve, or the power had been cut and thawed bit, and refroze everything up. I turned the power to it off and using a hair dryer thawed up everything and dried it out good. hearing the motor trying to dump the ice and not able to was first clue. Once the ice melted sufficiently it would dump water and ice in the ice maker. I've had to do this a few times. When disconnecting make sure your generator is running or that the refrigerator/freezer is on propane and DC and....and the water pump is on,and batteries have or have been switched off when unit is being serviced...and they neglect to tun it back on before, it thaws just bit.
In 15 years o problem that turned out to be the valve at the ice maker other than freeze up.
