Thanks Rick for pointing that out. I should mention that several months ago that only after several other checks, including shooting temps on the compressor and coils, confirming no leaks on the door seals and pulling the unit from the boat cabinet to assure I had sufficiant air transfer did I make the decision to tap into the freon circuit to attempt to charge it.My thinking was that for $150 I didnt need a professional to tell me there was no way to charge it. At $1100, and it not working anyway, I didn't have much to loose. I added freon and the fridge worked a couple of months. And cooled better than it had new.
When I got the boat late friday PM I had gathered supplies and was ready to try this again. I used the sniffer in the upper and lower cabinets, showed no leak, then sniffed near the compressor and my recently installed saddle taps. No alarm.
I promptly hooked up my borrowed gauges and proceeded to accidently overcharge the ststem, I turned it on and the compressor came on line for about 2 seconds and stopped. The fan continued to run and 30 seconds later the compressor fired up again and stopped again same as before. A few more tries and the same result and I realized I had WAY too much freon (true).
I pulled the line from my freon tank and cracked both the Hi and Low valves and allowed the excessive pressure to escape (true). It soon became clear that my saloon was beginning to fog up with the bleed off. Interesting enough- I felt the ambient temperature around me start to rise and the water in the toilet in the front head rose about an inch (BS). Climate change maybe?
I'm not sure, but I opened the stbd door and put a fan near it to let it escape.
I was very tired by then, so I went on to bed. Woke up around 6:30 refreshed and the first thing I noticed drinking my Community Coffee was that I had charged the unit with R22 (should be 134a). I had the 22 there to freshen up my front AC unit (true). Dammit!
Needless to say, I put the fan by the stbd door again and proceeded to evacuate the entire system. I shot some 134 in and evacuated it again. Another shot, kicked the compressor on, then back off again and after evacuating it this time I charged to the correct pressure with 134a, where it is cooling great (true)! Ran it all night and all day today and everything appears to be fine. Say Rick, where can I get one of them there "dial-a-charges" at. Just in case (BS)?
