Hi ronio,

I'm Harvey the Master Plumber.

Your problem is: After the power went out your Zephyr hood lights and fan don't work at all. There is a faint glow on the digital display but the fan and lights don't respond to pressing the control buttons.

First check the circuit breaker. If OK then check the transformer in the unit. It's next to the fan motor. If no power on the high side then you have a loose or broken connection. If you have no power on the low side the you have a bad transformer. If OK then you have a bad control board.

Feel free contact me again!
