What sites code 12 mean please enter description with code then I can help

that is a code of power was turned off and then on during a call for heat. Let the blower run 90 seconds and then post either a new code or what happens after the 90 seconds. OR you read the code wrong and it is 21.

It a limit open. Check filter and ac coil. If both or one is dirty can make limit to trip. I also check if you have vents closed.:thumbup:
