    It's interesting how the motor doesn't have some sort of radiant heat barrier to protect the motor from overheating since the heat exchanger right there but it is an engineering thing. As always keep up the great work you do and very useful information as always. 👍

      I was thinking the same thing. I feel that the metal plate isn’t sufficient enough to shield the motor from the heat generated by the heat exchanger. I’m glad you enjoy the videos.

    Good morning, I would check amp draw with the the panel door close to read appropriate 👍🏼

    Interesting, haven't seen that yet. Nicely done

    I did that same exact thing a year ago. Lucky there was an identical unit close by . Tried the other motor on the malfunctioning one and first thing I noticed is a good motor will run faster. If they die they spin a bit slowly causing hi-limit to open .

      Great idea to test with a known good fan from
      another unit. You get a 👍🏻 from me. But Carrier / ICP gets a 👎.

    I had a similar issue with one of these couple years ago. Replaced motor and thought all is well. Limit tripped again few days later. Found there is a technical bulletin from Carrier on intermittent high limit fault. Basically they send a new switch and you have to do a little rewiring. Maybe your outcome will be different. Thanks for the videos!

      That's interesting, it seems like that wouldn't have locked out the blower though.

    The company I work for installed about 20 of those at 2 schools December of 2022😬 this is good to know!

    Thanks for the video. I've not run across that style fan and it helps to be prepared. Be well...

    Nice work Nighthawk.

    A snap to replace. However, motor burnout looks like it could be a common problem due to the fact that it was designed to sit much too close to the heat exchanger for my liking.

      I’d have to agree with you. Maybe some better protection then a metal plate.

    Wonder if all the brands will use this type of blower? Thanks for videos!

    I hate seeing them going to this type of motor since centrifugal blowers are still more efficient and it costs more to develop and manufacture these high-flow axials.

    Where did you get the low voltage information from.Thanks

    You’ll know…, next time. No worries

      Literally the easiest blower to remove and I do it the hard way. Lol.

    What kind of stupid design is that? A propeller fan to push air through a system? That type of fan is not designed for higher static pressures. Not to mention it’s an ECM and we all know about the reliability of those. Then locating it directly over a heat exchanger, seriously? I realize the equipment manufacturers are trying to squeeze as much energy efficiency as possible but in my opinion this is a very poor idea. I bet that fan motor is mighty expensive too.
