I have 1200 LRIM Norcold four door refrigerator
Replaced both heating elements and refrigerator working, ran for a week
Shut off refrigerator and started 5 days later and the fuse popped and replaced fuse and ran refrigerator on propane and working
When to put it on electrical it pops fuse again
Just one heating element causes all this
It is a new one
I put the wires back into the same location on circuit board
Any ideas what is causing this
Thanks

2 different styles of heating elements used based on Cooling Unit S/N so
which did you order?

Older style...90* bend ((618872) CU below 11231146
Newer style...45* Bend (630807/638372) CU above 11231146

Leads on each element connect to alternating terminals on circuit board
AC_LO & AC_HI
(AC_LO2 & AC_HI2)

With all 4 leads removed...new fuse
Connect ONE element leads to circuit board
Fuse doesn't blow
Connect OTHER element leads to circuit board
Fuse blows................
Unplug leads...new fuse and reverse which element leads you connect
Fuse blows same element....bad element

Fuse only blows when 2nd element leads are connected...then bad circuit on circuit board

Thanks for responding It is new circuit board
Have the right heating element
As I said it was working on electrical, shut down for couple days started it up the fuse blew, did nothing to refrigerator while it sat there
Just doesn’t make sense
Thanks again
