I have Hampton Bay ceiling fan Winward ||
I replaced a lamp there. Now I cannot turn on the light.
The fan itself works fine.
I use the remote control unit to operate my fan.

Test the old bulb, chances are it is OK too. Try holding down the light button on the remote for 10 seconds. This should cycle the dimmer feature and take you back to full light. Does this fan have pull chains and have you tried them?
