    New thread old question; GE motors

    I have a thread that I posted about a GE 3/4 HP condensor fan motor running hot. It was the third motor that had been in the machine. It has run for almost a month but it also failed.The amp draw is fine, the fan blade is right, the capacitor is new, the coil is clean, and all circuits are...

    water softener in a hydronic system

    Thank you both. As far as using distilled water for feed I had thought about that but it would take a lot of distilled water. When we flush the strainers wich we do about twice a year at this point it uses about 400 gallons. and the boiler and feed water systems are on a rooftop well accesable...

    water softener in a hydronic system

The second company who tested the feed water said it was to hard and also had a little bit of iron in...

    Rooftop Barometric Relief

    I work with large VAV air Handlers frequently. All of the machines I work with use powered exaust. This can be controlled by a diferential presure switch.

    Apartment Building Dryer Exhaust

    Dryers dont shut a damper or stop air flow when they turn off so you are going to get air flow at all times through the duct. You want to use a explosion proof motor though with the exaust fan. Dryer lint can ignite easily and when it does it flashes. I would put spring loaded lead element fire...

    GE motor running very hot

    Thank you for the replies I think there is a misunderstanding about the nameplate abreveations. LRA Stands for locked roter amps and RLA stands for rated load amps unless I was taught wrong. I will check that. As far as checking with GE that has been the most frusterating part of this. GE lets a...

    GE motor running very hot

    This is a sealed bearing motor and I am mesuring the sidde of the motor case in the middle with a wire thermister taped to the side. This is not very acurate because the fan is blowing over the thermister if I shut down the unit the temp runs over 200 deg because the fan stops and of course the...
