Norcold 621 Refrigerator AC malfunction
Works fine on LP! Was working fine on AC until a few days ago. Tries to start up on AC on shore power or genset, doesn't start, displays error code "A." At that point the GFI at my house pops off...

From a remark by a tech named Doug on another heating element thread, if you cannot get the failed one out, you can put the new one into another "slot" on the cooling unit. Last time I worked on one, the 120VAC element was very hard to remove but I finally got it out. The fridge was a Three Way, which adds a 12VDC element to that extra slot. But most of these fridges are only Two Way (LP Gas and 120VAC) leaving that extra slot.
The 120VAC element is two wire and there should be no continuity to its metal shell. If it develops that continuity as it heats up, it'll trip GFI. If it develops continuity (less than specified resistance of around 40 ohms) then it'll blow the 5A fuse.
