One of our church furnaces has been sounding – too much “sounding.” The noise became quite obvious these last few days – even with the furnace room door closed.
Apparently the furnace fan motor finally burned out. The repairman found that! Along with a shaft on the fan that appears to be a bit off center.
As he explained – the motor goes at quite a speed in order to power the fan. When the fan goes even slightly off, or the cage for the fan is not quite fastened tightly – the fan can start to shake. After a bit of shaking, it rattles and then it rolls (vestiges of a song here!!). Soon the motor is fighting the fan.
The fight ended today with the motor burning out. Now we will get a new fan and fan cage. And a motor. And all should be well.
At least, well enough that I won’t be listening for that horrible screeching that I heard so loudly the last while!!
