Why does it starts up then shuts off and all the lights start blinking

Hey friend, I appreciate your post!

I see that your Frigidaire air conditioner will start up then shut off and blink. It could possibly an issue with control panel or the power source of the appliance. I would attempt to perform a reset on the air conditioner which would be removing the plug and pressing the "Test" button, you will hear a click and the button will pop out. Then press the "Reset" button, you will hear another click then plug the appliance in. Those are the steps to resetting your air conditioner, if that does not successfully correct the problem please reply back. I look forward to your response. -Matt
