Sub-Zero 561 Refer. Condenser Fan Motor problems

7 posts in this topic

Hello oh Wise Ones,

 

Newby here looking for assistance. I have a Sub-Zero 561 that has a Condenser Fan Motor (CFM) Problem. The fan motor is not rotating regularly. I noticed it not spinning and gave it a flick and it started spinning and cooloing the condenser. i watch for 10 min and continued running. Then checked agin and it was stopped. Flicked again and it ran for a while, slowed down and stopped. Flicked again and it runs. I am no rocket scientist, but I am pretty sure I should not have to flick this fan to make it opperate. 

 

I have ordered a new CFM and it is being shipped. In the meantime, could ther be another issue with either the Starting Relay, Running Capacitor, Overload Protector or even the Defrost Timer? I found it a bit strange that the fan sometimes ran very slowly. Is this a multi speed fan or just one speed?

 

I have a multimeter and the knowhow to use it, but am not sure what to check.

 

Any help would be much appreciated.

 

Thank you in advance,

Set your mind at ease...the course of action you're on is the correct one...if ya wanna mitigate any possible damage to the compressor/relay/ol ,as well as improve condenser sub-cooling, a small desktop fan blowing across the compressors until your replacement fan comes will do a fine job.

Dean ,  nothing to worry about , you do have a bad fan motor

the single bushing that the motor drives on get's dry and the motor does just what yours is doing

if you want , and can do , you can drill a small hole in the silver metal cap on the back of the motor ( not to deep just enough to break trough )

and put a little electric motor oil in there , don't soak it , it will take a little while to soak in to the bushing , this may get you by until your new motor comes in

New condenser fan motor will takes care of you problem.  Kit should come with everything you need.  Make sure to have a stubby phillips head screwdriver and 5/16 nutdriver handy.  Might be good idea to have gloves or a towel to protect your hands.  The surrounding tubing and old fan motors gonna be pretty hot.  Be sure condenser coil is clean.  Even if it looks clean shine a flashlight through it to be sure.

Just a heads up, those condensor coils can get really clogged up! When we service them we blow them out with Nitrogen. The dust and grime on the coils can get really caked on there. I have never tried it before, but maybe keyboard cleaner or something of the like would be a good diy substitute.
