It's a high pressure switch. It keeps the unit from running when the coils aren't being cooled, such as when the water pump is inoperative or blocked. It seems their next generation unit had low and high pressure switches. If it turns out to be the compressor, I will call someone, but why would I call someone to replace parts that probably cost $25 or less?
