Hi All
My dash AC worked when i got it (topped off by the PO in 2017). It was converted to 134 years ago. I was tired of sweating everywhere we went (OK, we're in VT not everywhere) so I paid to have it leak checked. HUGE leak in the condenser. So, I ordered a exact condenser, and the dryer and i managed to twist the hose that went to the dryer (I expected a different part to spin), put it all together, borrowed a vacuum pump, got the whole pressure manifold things, pumped it down and it held!
Then I filled it with duracool i ordered. I can't remember how many cans- somone said put in X cans to the GMC motorhome. It was the end of the year, it worked and we were happy.
This year we only took one trip and I noticed that the AC blows cold but cycles, cold for 30 seconds, off for ~30 seconds. So I thought I should add some more refrigerant.
I did, and am at the top end of the duracool dial that came with the kit (I didn't put the whole manifold on). At the top end of the "green" zone it still cycles. It was certainly good enough; kept us cool but I'd like to have the right amount. Do i go by the duracool gauge? what pressure should I have? Could I have put too much oil or something else in it?
The yellow zone ALERT starts at 45 (pounds?) Filled is 25-45. I am at 45 and cycling.
thank you
