    This, by far, was the craziest thing I've ever worked on.

    Ok, so more dye was put in the system. Went back the next day to find the evap full of dye. Perfect, the evap is shot. Just before I'm about to condemn it, something tells me to check around a little more - why is there dye on the floor of the freezer? And maybe I've been watching CSI too much, because I see - a spray pattern on the evap?

    Pump 'er down again, ramp the nitrogen to 300#. All the sudden PSSSSSSS - out of a braze joint right by the solenoid that runs behind the evap - spraying a pretty picture. Drop the pressure to 200 and literally NOTHING. Spray soap shows tiny bubbles. Ramp it back up to 300, blows the soap off the joint. I've never seen anything like this in all my years.

    Rebraze joint, vac and recharge - returned two days to a full sight glass.

    Perplexing, for sure.

    Good head scratcher. Now you need to go to church and repent for all the foul language you used on that unit. lol

    I worked at the county jail also. One of the reason we cannot served at the Jury. We might ended up seeing each other at the jail .

    Could be a king valve has happened to me before

    I had an issue where one of my king valves was bleeding off refrigerant once the pressure got about 250 psi. I would check the valve and see if it bleeds once the pressure on your nitrogen bottle starts to get around 250 + just close the valve completely and see if it holds. If it does than it's definetley the valve.

Told customer to run down to hardware store and pick up buzz bulb. Which I installed for her. She called following morning. She said it went off at 9:00 PM caught next door neighbor's kids with a bag and a piece of hose. Neighbor paid bill.

    It screws into a standard light socket and buzzes when you turn it on.

    What does a buzz bulb look like ?

    Is "buzz bulb" a standard term for this item?

    Does it look like a light bulb but makes a noise?

    How loud is the noise?

    I am sure that I have never seen or heard one. Or even Heard of one - before now.

    I have not seen one in a few years. But it was shaped to fit in a light fixture with a speaker on the end. Last time I saw one was in Lowes. Check amazon.com.
