So last night as the big storm was ending and our power had just come back on my CA shut off and allegedly made a very odd sound.

I say allegedly because my wife claims the monitor top did it, and it sure sounded like it came from it but I'm not entirely convinced. I don't see how it could have......
It seemed like it shut off and made a WHOOOSHHHhhhhhhhhhhhh sound similar to when an air compressor shuts off and unloads. It was quite loud and lasted probably a good 5-6 seconds.

We were all in the kitchen and it was enough that it made me stop talking and say "What the hell was that??!??!" Her response being "That was your fridge".

It cycled many times after that and seemed totally normal. I can't really judge the frost pattern as we've lost power a few times and it's pretty raunchy looking.

It's been running for a while now chattering a little, I believe I need to bleed some NCG but haven't gotten around to it. It's a cap tube conversion and was never bled and has been running since July of 2015.

I can't imagine what would do that....unless the intake valve was stuck open for some reason?
Last time I checked my CA wasn't equipped with a reversing valve and that's the only thing I've heard sound like that.

I honestly don’t know what would cause that. All mine does is go bloop bloop when it’s off.
	I have to keep telling myself that this is a healthy addiction! It is all in the name of preserving and enjoying these wonderful machines.

If the inlet valve was stuck, the compressor would spin backwards upon power loss; and make a puttering or freewheeling sound, not a whoosh.

Don't forget about the unloader.

So today I bled, and bled, and bled and bled.
I then did a hot water bag in the evap and got it good and warm to drive any oil out. I kept feeding it trays of hot water and kept it running a long time. By the end of this the entire condenser was good and hot as was the top of the cabinet and the bottom of the float was warm. The strainer was hot.

My power consumption is back down to the mid 150w's. And I'm almost positive my frost line is back where it belongs.

However, it's still chattering.

It starts off normal and then slowly gets louder which is the opposite of how it was for years. It used to get quieter as it ran.

I don't know..

I tried blocking the condenser for a while and then tipping it a little to try and help more if it's an oil issue. No change.

Here's a short video of it's sound. It's not horrible in person, just a hint if the tinny rattle going on. Also...I have no idea if it's normal but the capillary tube vibrates.

Maybe I'm nuts but after 5 years you get used to how something sounds and this has changed.

Like if you hold your finger on it while the machine is running?

So after the bleeding on Saturday and more on Sunday as well as the hot water trick and I tilted the fridge a little to the right side while running things seemed worse on Sunday.

Monday evening they were greatly improved until I put some bottles of water in the freezer, then it got a little louder again. Once things cooled down it quieted back down.

Now I notice it's 80% normal but occasionally I hear it get a little louder. Hmmm.
