    This was a video I did last spring thats been sitting on my computer for a while. Here is the link to the Pin removal tool kit I bought. I got this larger one because I wanted the best chance of getting the needed sizes. As always thanks for watching and supporting the channel. amzn.to/3HI8BCS

    Haha nice man. I spend 50% of my week on these Carrier RTU’s and when you said there was a call for cool but contactor wasn’t pulled in, I was yelling “go to the economizer plug!!” at the screen
    Those wires to the economizer tend to short out on the blower housing a lot of times too

    On the schematic, the jumper plug is shown between the plug and the economizer. For some dumb reason, some are male, and others are female. Leve it up to Carrier to screw up a wonderful idea.

    The BAS should be controlling the economizer, that's how I set it up on most of my buildings. I was surprised to see a jade controller in there. Alternatively you can setup y2, on a carrier rtu y2 will activate mechanical cooling if free cooling can't keep up.

    • @HVACRSurvival
      @HVACRSurvival  7 місяців тому +1

      You’re right on y2, a lot of people don’t understand they need a two stage thermostat for a single stage AC with economizer. This place has a cut rate budget, is why the economizer control is on the unit. like I mentioned, we literally took thermostats and put them in the return air ducts prior to this, and had to go on the roof to adjust them. This is in a secured building that couldn’t allow the thermostats to be available to the occupants below.

    When you checked in between r and c it only showed 24 volts and the control transformer is wired for 240 when it needed to be tapped for 208v I think you said you swapped them at the end of the video but whoever butchered that economizer needed to be fired lol

    • @HVACRSurvival
      @HVACRSurvival  7 місяців тому

      You’re correct. I like a little more than 24.0v if possible. I’ve seen more issues with lower voltage. 26v-27v is normal. Normally the circuit boards cut out at 29-30v.

    BAS does not appear to be controlling the economizer.... would have checked Jade economize module before checking signal at economizer. Possible that Jade was not configured correctly or a bad sensor leading to no free cool or mechanical cooling? Always should leave factory jumper with the economizer, I put jumper wires through econo plug.

  • @zashbot
    @zashbot 3 місяці тому +1

    I had one with a failing outside air sensor and of course no jumper plug. You can use thermostat wires and just shove them in the empty plug in the right spot. Just look up what the jumper plug looks like.

    The terminal release tools are pretty nifty, especially those ones on the ring, real easy to carry around. Not the biggest fan of the molex plugs that are completely open and exposed. They’d be better off using weatherpack connectors like machinery and cars do.

    Would you know what a capital B suffix after the horsepower rating on a direct drive blower motor means? For example Hp-1/3B. I don't believe it stands for insulation class as that information is usually elsewhere on the motor data tag.

      👉Here’s what I found.
      Design Letter (DES, NEMA DESIGN, DESIGN). NEMA defines four motor designs (A, B, C, and D) in terms of torque and current characteristics. (see tables below). Most motors are design B because of their comparatively high efficiency and torque characteristics. Design A motors may be more efficient but are used infrequently because their relatively high starting current can cause nuisance tripping of motor protection circuitry. Design A motors may also require larger than standard size starters.

It's a Lennox 81G5001 and you would think if you matched it up any replacement motor it would work. But it doesn't. (Emerson K55HXJJS-2903) Well, a Dayton doesn't work. Maybe Lennox is proprietary?
