Mini Split Shake

[Fueler]

My outside unit has developed a shake.
I assume a fan bearing.
Is there anything else in the way it operates that would cause a shake?
Thanks

How bad is it ?

Make sure the fan blades are fine, motor mount, etc.

Are you sure the vibration is not coming from the compressor ?

 

[Fueler]

Not sure of anything. That was my first guess based on visual and sound.
I did ask what else can cause a shake so I would have a clue as to what is next.
What causes a compressor to shake or cause shake.

Thanks

Grab the fan and see if is there is some slack play.

Normal operation will not cause it to shake.

Normal operation will not cause it to shake.

Of course.

 

[Tracs]

Of course.

Then don't ask if there is anything else in the way it operates as to why it would shake.

Mini splits can't get Parkinson's. Something is out of balance or it's resonating.

Check fan blade for cracks and even missing pieces. I have seen a lot of fan blades on units that have developed cracks. More problems with them than compressor shakes. I have seen compressor internal mounts break, and unit shake and make noise on starting and turn off.
