Product review (4 stars): works great once you figure out the correct wiring diagram
It did what it was supposed to do after trying all three wiring options. Took several days to find out but I got it. Defrosts every 24 hours so after 2 days of no defrost I finally got the 3rd try correct. Oh BTW I work in electronics for a living. Definitely if self installing, have patience or a degree in EE. All is well,  just wish directions were more clear
