Hi, I'm Robert. Welcome to JustAnswer. I'm reviewing your question now and will post back with your reply momentarily.
When you are in Auto and plugged into power the fridge should always want to run on AC power, if you loose the AC power it should default to LP. IF all the lights are flashing it could be putting out a code. I would need to know the make and model of the fridge to start, should be a sticker inside the door with that info, most are going to be a Norcold or Dometic but the model number will help on this.
I am around daily so if you need more time to get the model number no worries, I check in daily and respond WHEN I can.

I got the model number, you are saying on AC power ALL the led lights are flashing but they do not flash on LP?
Robert
Stand by let me check something.
Robert
This sounds to me that you have a faulty circuit board, there is a relay on the board that passes the AC power to the element. What I would do is verify the outlet the fridge is plugged into has voltage. The fridge uses DC power to turn on so if you were missing the AC power at the outlet the fridge would still turn on and work. Also under the outside access panel is a circuit board, on the board are some fuses. Make sure the fuses are good. UNPLUG the fridge before checking the fuses you do not want to grab the AC fuse when it is plugged in.
Finally I would ohm out the AC heating element. Below is a service manual for you that talks about the fault codes and points towards a faulty circuit board, I would however check the outlet, fuse on board and ohm heating element out before replacing.
Robert
No problem at all, below is the link for the service manual, let me know if you need more help.
