Fridge Status : Fridge is warming up.
Base temperature unstable issue: After initial LHe transfer, The base temperature keep going down, hit 7.5 mK and then bouched back to 1.3K. This might indicate a mixture ratio tuning.

Prof. Paul said if the transition is not within MC , we wont see anything lower than 20 mK.
I tried lowering the circulation rate by closing the VT valve, it seem to be coming back to 7 mK range. Stability still needs to be checked.
Transfer stick O-ring issue: After 2nd transfer, tranfer stick was leaking badly at the joint and transfer wont start.
Replacing o-ring seem to be helping.

No LHe transferring issue: Cant start a LHe transfer now. Either there is lot of frost build up inside Main Bath or other issue.
Initially suspected LHe level meter is faulty. Didn't find any broken wires on the slot and it doesnt change values when I jiggle the cord at the joints.

After letting a transfer go for an hour, tried to start 1K pot, no pressure. Added exchange gas to IVC, no exhaust buildup, which indicates no LHe inside Main Bath.
