Wrong sensor. The code is for the AMBIENT temp sensor. What is strange is, they rarely fail and the OP states he replaced it about a year ago. He needs to check his Ambient sensor and how it plugs into the upper control board. Doug
I know the code says ambiant sensor but for some reason I have found to many times the freeze sensor fixes the issue
And it is the white wire that goes into the coil and plugs into the box in the ceiling
