Your readings sound normal. The board supplies 120V between the AC HI and AC LO heater terminals, which is what you're seeing, so it's sending power to the heater. If the AC heater code shows up after that, the board is saying the heater isn't drawing current, which usually means the heater is open or its connection is bad. Check the heater's resistance with it disconnected. If it reads open, the 618872 AC heater fits the 1210IM and is in stock.
