What are typical low and high side pressures? I'm getting 4 PSI on the low side and 210 PSI on the high side after 30 minutes of compressor running.

If I unplug the fridge, and let it sit 15 or 20 minutes before reconnecting, it funs fine for a day or two. Then ice starts melting again. When it happens, the air coming out of the evaporator feels cold to me, but apparently not cold enough to freeze water. Both fans in the freezer, condenser fan and compressor are all running the whole time. Evaporator is not iced up. Condenser is clean. I hooked up gauges and I got the above pressures. Does high side sound too high?
