The furnace is working good as far as I can tell,But my Infinity Control shows these codes 12,32,and 43.
In early Jan. I had a bad regulater on the lp tank outside and the gas was cut off for a day or two and the furnace was not,this may be one of the codes.
When the heat is on the Infinity shows the Inducer RPM changes a lot I have watch it go from 2100 to 1950 to 2200 to 2400 to 1800,just every where between 1800 and 2400,BUT it was doing this before the fault codes,( I was going to ask about that before this happen ,but never got a round to it).
Thanks
Bill
