    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

    looks like a more compleate picture is in order. first of this is a reheat system in a commercial bld. that means coils in the air flow throughout the bld that heat air supplied by a large vav air conditioner. There are about 35 coils per bld. These are three story buildings with all the...

    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

    So if you saw my earlyer thread I am having problems with a hydronic system getting clogged with solids. I got a lot of good advice and now I think I have a handle on what is causing my problem. The second company who tested the feed water said it was to hard and also had a little bit of iron in...

    Closed loop hydronic lots of solids

    I Have a system that is called a reheat hydronic system for building heating and cooling. It has a Laars 1million BTU boiler with a boiler loop pump. This drops onto a large loop with one grundfoss pump. The building has small coils throughout that heat air to diferant zones as needed. The...

    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. I have trane machines that use the percentage that the economizer is open. I did have a building that was getting over pressured even with...

    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...

The unit is two stage with two compressors and twop condensor fan motors. both motors and fan blades are the same. its a york and they gave me a discription of the motor. so I know I have the right...

    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...

    GE motor running very hot

    I have a small ge moter in a packedge heat pump that is running 190 F. This is the third moter in this unit. Its a 230 volt single phase condensor fan moter. checked and double checked every conection. Amp draw is 3.7 and the name plate rates the RLA at 4.8. This seems way to hot. Also GE has a...
