So after fighting with the A/C u it for the past 4 Days I am stumped. I used Barnicle Buster on Friday and let it sit and bust loose all the crap for 6 hours before I restarted the unit and to my surprise, it made absolutely no difference. The unit in my guest bedroom will run for 2 minutes and shut off. After 30 seconds it restarts the compressor and immediately shuts back off. It will do that for a total of three times and then display the "low/ps"
I also removed the water intake and out going lines from the unit to make sure that we had good water flow and we noticed that the copper line coming from the unit was a little squished, so we rounded it back out and that made no difference. I have very good water flow from the discharge thru-hull.
On Sunday A buddy of mine came down to throw some gauges on the unit and see if we were low on R22. We were showing 60 PSI. Here is what we found weird. It appeared that the reverse valve was stuck in the middle and wouldn't fully open or fully close. We tapped on it and and got it working after about 20 minutes of tapping and messing with the wires. So when we cycle from hot to cold we were getting hot and cold air like it should. But, it was still shutting off after it ran for two minutes. We also tried bypassing the high and low pressure switch and that made no difference at all. (all we did was used a jumper wire between each terminal and not sure if that actually bypasses it)
What we did notice is that the low pressure line on the top of the compressor is not getting cold but the line to the condenser is getting ice cold when we are set to cold. My A/C guy is saying that the line on the top of the compressor with the fill fitting on it should be getting cold when the A/C is on.
I also tried swapping the SMX 2 control panel with the one from the salon and that made no difference.
Does anyone have any idea what could be causing the issue or does it sound like it is time to kiss this unit good bye
Thanks in advance
