Its not producing ice anymore.

As long as the ice trays are filling with water, it's not actually the function of the ice maker to make ice. Ice simply forms because the freezer compartment is cold.

The icemaker's function is to sense when ice is formed in the trays and to dump the ice into its container.

This requires the use of a thermostat to sense the water/ice temperture and 'tell' the icemaker when it's time to dump the ice.

During the dump cycle, a heater briefly comes on as the arm swings through the ice cube compartments to assist in loosening the ice cubes and make them easy to dump.

If the icemaker is filling with water but you get no ice, I suspect that either the control circuit (thermostat, relays, and wiring) is not 'telling' the heater to come on, or the heater is burned out.

Some units also have a timer circuit such that both the timer contacts and the thermostat contacts must be close in order to initiate a dump cycle (i.e., it must be time to dump and the water in the cubicles must be frozen).

A skilled homeowner could make these repairs, but if you don't feel comfortable taking your icemaker apart and testing the components, I advise leaving the job to a qualified repairman.

I hope this helps. Good luck.
