## Questions & Answers

**Q: Will this work for Sub Zero 532?**
A: Yes, I believe it would work on 500 series Subzero

**Q: Will this work on freezer sub zero 501 f?? thank you**
A: It should.  I would recommend looking at your existing part and make sure the connector pins match the photo.  The plastic housing looks different, but the screw holes should line up.  Good luck.

**Q: Will this fit a sub zero 632?**
A: This is a very common part. Not for sure. I would bet it will.

**Q: Will this work 550 sub zero**
A: It should work just fine, however to be safe, I’d pull the timer and check the original part number. It’s up top (behind the large grill) towards the center. Not too difficult to remove...probably more of a challenge to get it lined up and back in place.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Works in my Sub Zero 561
*by E***E on January 24, 2025*

Easy to replace my old timer which was making a loud grinding noise although it still worked.The part spec for the Model 561 says that the 3081180 is a 6 hours / 21 minute timer (i.e., 6 hour cycle, 21 minute defrost). The spec on the Supco is 8 hours / 20 minutes. It doesn't seem to make a difference - the freezer performs well. In fact, the old timer that was in my Model 561 was a 3081110 (24 hour cycle) - I guess it was replaced at some point in the distant past?

### ⭐⭐⭐⭐⭐ Save your money…on professional repairs
*by G***K on May 22, 2024*

This unit arrived the next day and fit perfectly.It took less than 5 minutes to install.Don’t waste your money or time on the Maytag man for this oneIt has been doing what it’s supposed to do now for several weeks..my 32 yo fridge is chill

### ⭐⭐⭐⭐⭐ Saved my Subzero!!!
*by P***Y on December 11, 2023*

The media could not be loaded. And at a FRACTION of the price of the OEM part. It has worked FLAWLESSLY for 2 years now with no indication of any trouble. Meanwhile, I have friends who haven't done well with the genuine OEM part. It's rare that you get a better product at a fraction of the price, but this is one of those rare moments. I highly recommend it. It's been great for me!
