I have a R-22 WFAH-16 with a 3 knob switch that is acting funny. From what I remember the "start" position would also start the march pump and it no longer does that (will start march pump on "run" though). The other two units (one is fine, one will be a seperate post) will start the march pump on start. Back to the 16- "start" starts only the fan, but "run" is fan and starts the water and there is a LARGE drain on the electrical (2 30A/120V) that slows the fans/dims the lights considerably. When switched to run, the compressor unit will make one heavy click sound and when switched back to start will do the same click again. Is this a frozen compressor or should I be looking at something else? If it's a frozen comp, will a WJAH16 be an easy swap (can get one on ebay for one more day). Thanks for your insight and let me know if you need anymore info.

When I take the old unit out, what should I do to drain out all the old lines to prevent contaminating the "new" unit?

Got it on ebay for $228 and hope the hookup goes smooth and it runs.

I share a building with a HVAC company that will do my old capture and new charge. Just wondering if there is any trick to a marine unit as opposed to a residential system.

The replacement arrives today. Is there a way I can bench test thie unit before installing it on the boat?

What about on the HVAC bench? Or should I just get the filter drier put on and then hook it to the boat and hope for the best?
