GE Refrigerator Error Code F606

F606 means the fresh food door icemaker mold heater is not producing enough heat. Specifically, the mold thermistor did not detect a 3°F temperature rise within 90 seconds of the heater being activated during a harvest cycle. The refrigerator monitors this as a safety and performance check to ensure ice can be properly released from the mold.

The refrigerator's cooling and food preservation functions should remain unaffected by F606 since the error is isolated to the icemaker circuit. However, the icemaker will not produce ice correctly while the fault is present. It is safe to continue using the refrigerator for food storage, but you should address the fault to restore ice production.

A power reset may temporarily clear the code from the display, but if the underlying component failure is still present, the code will return as soon as the icemaker attempts another harvest cycle. Resetting is useful for confirming whether the fault is intermittent, but it does not fix a failed heater, thermistor, or wiring issue. A proper repair of the faulty component is required for a permanent resolution.

A knowledgeable DIYer can test the mold heater for the correct resistance of approximately 110 ohms and inspect door wiring connections for visible damage or loose pins. However, replacing the heater, thermistor, or icemaker module requires disassembling the door-mounted icemaker, which can be complex. If you are not comfortable with electrical testing or appliance disassembly, a technician is the safer choice.

Repair costs vary depending on which component has failed. A replacement mold heater or thermistor typically runs in the range of $20 to $60 for the part alone. An icemaker module assembly can cost $80 to $200 or more. Adding professional labor, total repair costs commonly fall between $100 and $350 depending on the diagnosis and your location.
