Product review (1 stars): this unit needs to go back after install in a home that needs to be sold.
Worked fine upon install 2 days ago, now will not work and has just been plugged in with no use.  Light, fan, was fine on install, now neither works and the units hums so loud it can be heard anywhere in the kitchen dining and living room so I can not leave it attached to try and sell the home.
I need to return this unit. which is a big headache.  If the seller will not ship another overnight, the home can not go on the market.  this costs money not to be on the market.  I will review further regarding seller response.  I am pissed
