We have the Broan Allure III range hood, had it about 2 years. One of the bulbs went out so we replaced it, the next day it blew that bulb. Took it apart to see what was going on, put new bulb in checked it before putting it back together both bulbs were working. When we got it back together turned it on and now the other side isn't working! !!/?@#! So now what, any help would be great. THANKS
