Good morning everyone - we are experiencing 120V compressor issues. Last night we arrived in St Augustine, FL and I noticed the supply pressure was down to 60lbs and the compressor was not running. Checked and it was very hot, like it had gone into thermal overload. So I left it off until this morning. Turned it on, pressure charged from zero to 105 and then stopped as it should. When pressure dropped to 70 I thought "it should be on by now ..." went out and checked it and it was hot and felt like it was buzzing, like the start capacitor had failed or the compressor has seized.  It is the Thomas compressor with the Spartan Scientific (Viton) pressure switch/regulator.

I like Richard's idea of replacing the Viton switch/regulator and will likely do this when I get the coach back home. However, in the meantime we would like to continue our road trip. I see some people have suggested replacing the Thomas with a small all-in-one unit from Harbor Freight - is this something that could be a full time replacement? it looks a little light duty for the coach, but it's self contained, only needs a 120V feed, and it's inexpensive.

Is there any issue running the coach without the 120V compressor? As I understand it's major function is to keep the coach level when the engine is not running - the 12V compressor can handle the doors and potties when parked overnight (have to work on finding level spots!)
