Product review (5 stars): For subzero 532
This 6 hour timer is a replacement for the timer that failed on my 20 year old sub zero 532. My freezer was icing up and not defrosting, making ice maker not work and also not getting to sub zero temps. After researching the internet I troubleshooted by advancing back wheel on existing timer till it clicked. Once i saw in 30 minutes that no defrosting had taken place I ordered this new one. Shipped extremely fast! Probably because I live in same state as company, CA. Simple to replace. Directions were quite easy to follow. Connected the weird extra wire to number one. This makes it continuous application. took a half hour for the defrost to start then a couple days for my freezer to finally get back to 0 degrees. But works perfect now and saved myself an expensive service call!
