I found the codes and wiring diagram inside the panel but cannot locate the part "high limit device". I do not know what it looks like either. The furnace model# AUD120C954K2. The fan runs but there is no heat. I replaced the filter; they were totally clogged but no change. I am an electronics tech but not an electrician or HVAC tech. Any help appreciated. Thanks, John
