IF the RED LED light on recall box was lit.......you would NOT be able to restart fridge by just turning it OFF and then back ON. When the RED LED comes on all power is shutoff and you have to reset the recall box to reestablish power.
Both ON and GAS LEDs flashing..........does this happen when in 'AUTO' mode, when in 'GAS' mode and doesn't matter....happens either mode?
Have you check the spark electrode/wire for continuity/
Gas valve solenoid resistance......79-85 ohms
Gas valve solenoid wires for continuity
Check voltage at terminal board between GV and GV GRD
I suspect a intermittent voltage problem vs the propane regulator.
Turning fridge OFF/ON would have no affect of regulator
