The original fan motor had 1100 rpms and the new one is 1075 could this be the reason why the fan motor keeps quot;amping outquot; after a minute of running or is it something else.
This is going to be the indoor fan motor Correct? You need to check the amp rating on the old motor versus the new one. This is a very common problem when replacing the blower motors, some people do not take in the effect that the amp ratings are very crucial. The RPM being only 25 under will not cause this. If you give me the model and serial number of the unit of the model # or Part # of of the old motor I could check to see if you indeed did get the correct motor
need to know if this is inside fan motor or outside fan motor...that little difference in rpm will not affect your motor amp load....what will make a difference is bigger fan, broken duct work allowing it to blow to much air...wrong voltage....just need more info...what was wrong with original motor...when and why did it start amping out...was new motor same hp and amp load of old motor(this will make a big difference especially if old motor pulled more amps than new motor)....you can email or im me and i will discuss this with you..
you will desire to have the capability to take heed to the comressor run. It makes a different sound. you additionally must hear a hissing noise from the evaporator coil (interior the homestead on the furnace blower) That noise is the equipment pressuring up. the lines additionally must be distinctive temps. the better line would desire to be cool and the small line heat. If thats no longer the case call a restore guy. a sparkling condenser will value around 900$ to 1200$ put in gazing the scale performance or maybe in the experience that your evaporator is compatable.
The speed is not a problem. Did you replace the run capacitor? That is what it sounds like. If the capacitor is good check the wiring to make sure it is right. Make sure the fan is spinning the right way.
