AC Heating Elements
Norcold AC Heating Elements/ AC Heaters for sale! (N610, N611, N621, N622, & N641)
The heaters below fit the N611, N610, N621, N622, and N641 model refrigerators. There are two different AC heating elements made for these model refrigerators. They both operate in the same way and both have the same technical specifications. The only difference is that older model N6XX refrigerator cooling units have a different diameter AC heater slot than newer model N6XX refrigerators. To determine which will work with your refrigerator, you'll need the cooling unit serial number. This number is located on a white decal on the cooling unit itself.
If you have an N610, N611, N621, N622, or N641 model refrigerator and your cooling unit serial number is below 11231023, you need:
- AC Heater 621702. Click the link to the left to view that product.
