Okay guys, new member, long time lurker. The missus and I finally bought ourselves a 5er, a 2004 Terry Quantum Ax6. It's huge and we have had it out a couple times. Got a great deal on it and we lo...

Since RV A/C, like room A/C and appliances such as Fridges and Freezers, are all Charged then Sealed:
1. If it ever ran and ran right, there can't be "too much" refrigerant. No way to get in and overcharge it.
2. If the compressor is getting sticky internally, The RLA (Running Load Amps) will go ABOVE the spec on the compressor tag. But this can also happen if the coils are dirty, fan(s) aren't working, or weather is really hot.
3. If compressor RLA is BELOW the label spec, then the refrigerant charge may be low, OR the compressor's valves could be weak. Low refrigerant won't cool well, but it may show up as icing on the Evaporator Coil. Poor Valves will show up as poor cooling, long run times, and a compressor that CAN start right after it's been running and shut down. The WHY is, the Head Pressure that normally has to bleed down before a re-start, is not as high in an A/C that has a compressor with weak valves.
