RBbonfire Posted November 18, 2022 Share Posted November 18, 2022 My heater won't change Modes. Stuck on the middle vents and won't change to floor or defrost. Anyone know what I am looking at in terms of repairs? Thanks. Quote Link to comment Share on other sites More sharing options...

Edp1 Posted May 3 Share Posted May 3 I have the same problem now with my sc430. All bottoms operate but the mode switch will not change the direction of airflow. It is stuck blowing on the window. Nothing changes when I send it to the floor or in my face. Quote Link to comment Share on other sites More sharing options...
