So the mom and pops campground I stayed at had 240V going to the 120V outlet. Both hot and neutral were 120V. I got that fixed but didn't realize it until the fridge got zapped. It is running off propane fine. I replaced the fuse on the control board and the entire main control board itself. When i switch it from off to auto the green light comes on for about 3 seconds and then flashes 3 times and it automatically switches to propane. I've checked voltage to the control board and it's 120V. The 12V DC supply is working to operate the igniter for propane. Any ideas?

Troubleshooting manual in the Files section is your friend

Flashes 3 times every 3 seconds indicates an electric heat fault.

Get you ohmmeter out and measure the resistance of the electric heat element. If open, replace. If grounded, replace.

Heater resistance should be 38-53 ohms.

240V whacked the circuit board and most likely the heater

You already replaced the Circuit Board...now it's time to check the heater
