Three usual causes in Murrieta homes: a blocked water supply line from mineral scale ($95 to $150 cleaning, often solves the problem entirely), a failed water inlet valve (the solenoid valve that opens to fill the ice maker tray, $150 to $220 replacement), or a failed ice maker module (the mechanical unit that ejects ice cubes and cycles the water fill, $180 to $320 replacement).
Diagnosis follows the water path: check line, check valve, check module. Starting with the module and replacing it when the actual problem is a blocked line is one of the most common misdiagnoses this service corrects on second-opinion calls.
