Hi
I have a 4 years old York Diamond-80 furnace/ac unit. Its blower motor(1HP) went bad and was replaced under warranty by contractor who installed the unit when the home was build.
When the mechanic was replacing the motor I noticed he pulled a little probe type rod (about 5" long and .150" thick) from the old motor casing and when he tried to slide it into new motor casing he had hard time. He then decided to connect one of the wire to a stud on motor casing instead of the rod where it was connected before(since there is no rod anymore). System operates and works fine but I like to know,
Is it safe or I should call them to put the rod/probe back?
Is that rod/probe is for ground only or it works as temperature sensor too? (I'm concerned about overheating)
Any help will be greatly appreciated.
Thanks
Dhaniyal

Exactly what color was the wire he connected to the case that previously was connected to this rod he didn't replace?

I'm not sure; there was so much going on and very quick.
What I will do now open the cover and use a mirror to check the color (it’s a horizontal unit and the blower casing installed upside down).

I have a feeling it will be a green ground wire. I have never seen a motor with any type of long probe sensor. The tech may have been working with the long thin bolts that hold the motor case ends to the middle motor case.
If the wire color is other than green, post the motor make and model.
