Thank you for your question on the model 763N exhaust fan/light. There are two white wires, a single black and a single blue wire inside the 763N. Make sure that when you are wiring the 763 that you connect both white wires to the house neutral wire. If you are sure the unit is wired properly and still not working, you can always remove the fan assembly and light assembly from the unit housing and try plugging them into an electrical outlet to make sure they are working properly. Please contact the Technical Service Department at 888-336-6151 if you need further assistance.
