Hey guys I have a RFG297
and I've recently had to patch a small hole in the evaporator pipe. After filling it with freon, I noticed a little oil leaked out when I was evacuating it. I'm not exactly sure how much oil, but i'm guessing no more than 5ml. Well, I filled it back up with freon till the pressure read roughly 115 on the high and 0 on the low. I was not able to get the exact amount of freon that I put in because the pressure started to rise too high before I could put in the 5.39oz that the rear of the unit specifies. However, I do not trust my scale, especially since it's measuring a small can of freon with a fat hose attached to it. Anyway, the fridge seems to be working well. I'm not sure I'm reading the temperatures accurately as I don't trust my temp gauge at 0degF, but in the fridge, it's about 3-6 degF off of what the digital setpoint reads.
My main concern is that the compressor always seems to be running, and makes this intermittent shudder/vibration noise. Does anyone know how much oil should go into that unit? The manual says it needs Freol @ 15c... idk what that means. Is there a way to tell how much you have in there? Is there a way to remove the oil in there and add a new charge?
Someone on this forum told me the pressure should be 0 and 105 on the low and high respectively, can anyone verify that?
