Subzero RFD361 Freezer not properly cooling

[jjbodean1970]

Hi all,

 

I have a Subzero RFD361 thats actually in pretty decent shape, but recently started having an issue cooling the freezer side. Thermometer indicates a temp around 26 F but there are warmer areas of the freezer that aren't keeping things frozen properly. Interestingly, the fan doesn't seem to be operating at all, though the light switch operates normally. 

 

I have attempted to take some items out of the freezer to improve airflow without improvement.

 

Thoughts?  Thank you in advance!

Well if the fan is not running that may very well be the issue,  most of those units have a separate switch for the fan then the light,  so look at the door switches,  try pressing them manually and listen if it runs when switch is pressed

thanks, my unit seems to have just a single switch at the top of the door opening to control both light and switch. switch pressed results in light turning off but no change in fan operation, stays off

Well, in that case sound like you might have a bad fan motor,  check for 120v at the fan motor to confirm

fan motor works, but only seems to be coming on intermittently, no rhyme or reason, blades spin freely, doesnt seem to be binding

could the defrost timer be bad?

so i had an appliance repair guy come out and the final diagnosis he gave is a restriction in the sealed system somewhere. cut power to the compressor, he said the pressure dropped to 20, brief hold, then 15, longer hold, before dropping to between 0-5. he said this indicates a restriction. sound plausible?

 

estimate to replace the sealed system estimated to be $1500-$2000, waiting on the final estimate still.

What was the final diagnosis/repair. I am having the same problem. My fan stopped running, could only get temperature down to 30's. I killed power at the breaker to reset the fridge and the fan started again, freezer cooled down to 20's but couldn't get to freezing. The temperature says it is 0degrees but water is not freezing.
