Will not work electric or propane. Any ideas?? First camper new member

If display works for just a few seconds it's most likley not a fuse or power supply. If display board also has controls, it could be a bad connection in cabling between boards. Next either board could be bad not recognized during start up. If in a pinch you can always connect A/C direct to chimney with a switch for manual control, not for long however.
