ON LED flashing 1 every 3 seconds indicates that the fridge is operating in BOS (Backup Operating System). That means 'thermistor' is not communicating with controls....either due to loose/bad plug connection at lamp assembly OR thermistor is bad.
BUT that should affect both electric and propane operation :H
Now if the ON LED is lit and it's the GAS LED that's blinking 1 every 3 seconds....that is an AC Fault Code.
Good AC power at outlet
Good AC power at lower board connection
Good 5A Fuse
Good AC power THRU that 5A fuse????? Clips holding fuse tight...AC on both sides of fuse??
IF Fuse good......Clips are good.......board is bad/AC power track
