My condenser polarity is correct.
Heat exchanger has labels which i followed when installing it last year. And the same is the case for the air condenser. i just made a mistake in schematic.
sight glass
I have bubbles but large voids of no liquid(i feel) but liquid is clearly flowing. It never completely turns into pure liquid with no bubbles.
I am assuming its locked rotor. compressors trying to start but not starting. As compressor tries to start, I see 40A on the AC mains panel. Now that i have a 10A circuit breaker, that trips within 1 second. with old 20A circuit breaker, I would shut it off about 1-2 seconds after I see the 40A on the dial. I never let it run drawing 40A to find out if old 20A breaker would trip. I was very cognizant of this and I made it a point to observe every startup. (PITA but wanted to make sure i don't ruin the compressor)
King valve on side of receiver
Cracked so I can
monitor high side. 50psi on startup, but rises up to 75psi. Air temperature is still chilly in RI. 50s, and ocean
water is 45F. Refrigerant line exiting compressor is very hot. And by the time it leaves both condensers its basically 45F. Maybe i'm running too cold?
suction line accumulator is connected backwards ?
Checked for the 10th time and it is correct. There is an IN label and that's where line from evaporator comes into.
4. The orifice inside TXV than a one O and preferable OO.
I have to check this.
5. Also report back the location and attachment method to suction line
see pics, and let me know if you need more.
6. Also report temperature of TXV 30 minutes after compressor start up. see pics.
Using IR thermometer that I calibrated against my skin, I had 0F all along the bottom of the freezer plate and at exit of TXV. prior to frost I might have had lower temperatures -10F i think but i will check at next cycle.
22F at top of freezer plate and at the exit of the bulb. I don't want to take off the bulb
insulation. Could frost be insulating my real temperature?
Ice cream is solid, so i am in dream land right now. Its just a matter of finding the root cause of floodback.
