Description
Replace the rear EG3 three-way power supply board in a compatible Norcold absorption refrigerator with factory part 618666. This board is for the EG3 control system; it is not the two-way EG2 board.
Manufacturer-documented applications
- Norcold 600 Series: EG3 versions of the 653, 663 and 683 models, including the listed 663IM and 683IM ice-maker configurations. Norcold parts list 619704 identifies 618666 as the EG3 power-supply board for the 65, 66, 68, 66IM and 68IM model groups.
- Norcold 6000 Series: the documented three-way 6053, 6063, 6083, 6163 and 6183 models.
- Earlier board reference: 61647622 is listed as the earlier EG3 power-supply board replaced by 618666.
Choose the correct control generation
The two-way EG2 board is 618661; it is not interchangeable with 618666 simply because the connectors look similar. Confirm the refrigerator model, whether its original controls are EG2 or EG3, and the original board number before ordering. This listing is for the rear power-supply board only, not the separate eyebrow/display assembly, ignition module or wiring harness.
