Product review (2 stars): Although Zephyr offered to replace the control board they will not cover the install with their recommended installer that I use
Warning....Zephyr policy post warranty.  I just had the main control board replaced on my zephyr hood.  The new control board stopped working 1 month after install.  Although Zephyr offered to replace the control board they will not cover the install with their recommended installer that I used.  So although they will cover the $100 part, they will not cover the additional $150 it will cost to install the part.
