This was a simple walk in freezer call that led to so much more.

    I'm an HVAC dilettante. The place I used to work had an HVAC store next door and I would wander in there and sometimes find something useful.
    I have fixed minor things on a few systems. Added freon, etc. Fortunately never messed anything up.
    Didn't know about receivers. Read more about them on the internet.
    The other day I pulled into a parking spot at a quick market. One of their refrigeration units was mounted low on the side of the building with the cover off. Because of this channel I was able to identify all the parts and explain them to my wife. She got bored.

    I really like you for not just flipping the disconnect back on soon as you saw it off. You never know, but there could've been a very good reason to have it off in the first place — running basic checks (looking for shorts and continuity at least) is always a good idea if you come across something that's been disabled before you got there. Most times, it'll be nothing; the one time it's something, it'll blow the entire board out of the box if you just blast it back on without thinking. 🙂 The entire point of troubleshooting is to assume that there's a reason something's the way it is — until you can clearly show evidence of it just being a freak occurrence. Everything happens for a reason.

  3. Egon Freeman says:

    Just one question… shouldn't that disconnect be secured off if it was done on purpose? Like, with a padlock, or at least a screw — so that it's clear it was done intentionally. When working on electrical systems where you've a full crew doing stuff (with check-in/-out logs and all), there's usually going to be a multiple-padlock system where each person going to work on something attaches their own padlock to the disconnect (or, as often, the lock on the switchboard case) — so that nobody can re-energise the circuit without removing all of the padlocks (each is keyed to a particular employee).

  4. Embermist69 says:

    Bit late to the party, but how much weight would it take for the disconnect to be flipped down. For I wonder if a brid with the right weight and landing could have turned it off since it flips down to cut the eletric.

    Heat producing device,that made me smile. When I lived in Canada trying to charge rooftops in stupid temps, I would never say we use our torches. We did sometimes if we had local power we would strap a crankcase heater to the can.

  6. K Z says:

    reason they shut it off because leak come out if valve screw in
    they think going cause more problems down road so they shut it off for reason for not danged ac or loss of pressure in tank but they should informed owner but they never did

    Wait during the pump down process the system was flooding back to the the compressor and the question is:Is it normal for the unit to flood back to the compressor.I ask this because I saw the pipe going at the compressor been ice cold.
