Thanks for all the help, guys.
Right now, I'm going to enjoy the state of denial. I have -5° in the FC and holding for two days, compressor is cycling. I have peace restored in the house. I know Murphy is waiting, but I may put off the ultimate fix as long as I have to. I appreciate the confirmation on 7015780. That's what I really needed, as I'm pretty sure it's on the low side, especially with a leak of 3 oz or so every 2 to 3 months. I know I'll have to face it sooner or later. Having components in hand when the time comes will be a big help.
