    Sears Roebuck Condenser Tonnage?

    This is for my HVAC brother, so I have not seen the unit.
    But he wants to know the tonnage of the a/c as he wants
    to install it tomorrow.

    (And he's too lazy to read HVAC-Talk. :)

    He says...

    Okay, back from my day. The heat pump was the first call, about 7:20am, because the lady
    had said it made the dreadful noise only when it was cold. I got there and ran around to the
    heat pump...

    Yeah, I was thinking that were there a problem with it being STUCK in defrost,
    they would have likely complained about the poor heating. They didn't. Of course,
    they DID say it would stay on for...

    Trane Heat Pump troubleshooting.

    Model 2TWR1030A1000
    Serial 30750WL4F

    This unit had only a schematic and some charging charts,
    nothing too useful.

    Elsewhere on the forum, I read that Trane heat pumps tend to
    use an outdoor...

    Gas valves with obvious vents.

    (The Search did me no favors.)

    I know a lot of gas valves on condensing furnaces, especially the ones
    with sealed burner boxes, had/have vents on their gas valves, but would
    it be a mistake to...

    Thanks for the heads-up. It won't let me edit, so I flagged my own post.

    Maybe your browser cached my old profile?

    Anyway, thanks again.

    Thanks for the attempt, Rundawg.
    The address in my settings is correct.

    I've never seen one of these units before.
    The ignitor was in a big separate cannister, not on
    the main board. The...
  11. One ignition attempt before lockout. Install manual, Bryant 577BNW024040 gas pack.

    I was troubleshooting it this past week and noticed it goes into
    lockout after just one FAILED ignition attempt. Lots of dip switches
    on the thing, but customer was not given manuals for it. (Not...

    I first noticed something was wrong when I heard the compressor's internal
    pressure release in heating mode.

    Then I switched to cooling mode and this time watched my

  15. Likely restriction cause on an unopened package heat pump.

    We didn't do the install and we've only been caring
    for it for six months--it is an 05-- so I'm not absolutely certain
    this package heat pump was never opened, but let us
    suppose it wasn't opened,...

    My brother does HVAC, but not this forum.
    He had a problem with high superheat.

    dry humor so I'm thinking the ice cube stuff is...

  19. Where to get replacement heads for Mastercool Hydra Swage?

    I screwed up and broke my 3/8" today.
    It is probably the one I use most.

    But I am suprised to not see any replacement heads
    sold separately from the whole kit, either from the manufacturer
    or...

    Is this a Ruud evaporator coil?

    The outdoor unit and furnace were Ruud-labeled.
    But the evap coil only had a few markings on its label.
    Curiously, it had no model number but DID have
    a serial number:
    3/4 38107

    The top line...

    But the circuits cannot all be flowing the same refrigerant. They must be separate.
    How is that accomplished? A diagram would be good.

    Sounds like a variable speed motor.

  24. How do multi-zone ductless mini splits achieve multiple circuits, heads?

    My google and search skills are not turning up anything about how these
    things work in regards to multiple heads. I'm thinking they don't
    have a compressor for each head/circuit, but I have no...
  25. Carrier 581BEV102125ADAA gas package, Low ambient control gone awry.

    I was rushed so I didn't really pause to check the schematic for clues
    on this, but this unit--which has two compressors and two condenser
    fans--would periodically stop one or even both of the...
