SB-130 alarm codes

I've got;

• 03 CHECK RETURN AIR SENSOR
• 04 CHECK DISCHARGE AIR SENSOR

I don't know how to clear them, anyone familiar with these? After I push just the clear button it goes away for a second or two and comes back. After messing with it I also seen something about "pre trip alarm" and "-28 alarm" I can clear the last one but still no go. I've somehow gotten it to start but it just idles. Seems rather fishy that both would go at the same time.

 

Yeah, figured I would call TK in the morning. Just hoping someone on here has had this before. Just dreading a dealer experience, if ya know what I mean, $$$

 

I stopped by a thermal king, and apparently it was just a bad connection on the board. They cleaned it up tested it and filled the refrigerant in my truck, was 2 pounds low. In all it cost me $150 bucks =(
