The recharge gauge said that it was in the charged range. The compressor kicks on, but continuously runs. I ran it for a half hour and it never kicked off. I put some dye in the system, but could not find any sign of the dye for a leak. I bought a set of manifold gauges and a vacuum pump, today. Tomorrow I will test the pressures properly.I have all the parts to replace the compressor, dryer, and orifice. just want to make sure it really needs it.
