    Incredible buy!
  

*by J***L on Reviewed in the United States on April 30, 2020*

This item arrived faster than anticipated and works great! Our furnace broke and this was the replacement part needed to become operable again! Thank you Amazon for such fast shipping!

    Short life
  

*by D***. on Reviewed in the United States on December 9, 2020*

Bigger than expected and died after 9 months. Purchasing now from a big box store I can return/replace with for just a few more dollars.
