We had 2 identical Hampton Bay ceiling fan with 4 lamp lights installed in our rental property. Both only have 2 of the 4 lights working. One of them had all 4 lights working for a couple months, but then 2 quit. The other has only had 2 of the 4 working since it was installed. The fan works fine. Trying to figure out if it's a possible wiring issue or if it's just strange luck to have 2 fans with this issue.
