its the relay inside that controls which speeds the hood works at this connects to the switch speed control
SOURCE: Zephyr Milano hood fan and lights stop working. Power is on.
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!

unplug the fan then remove the batteries from the remote then plug the fan back in and, reinstall the batteries; this resets the fan control
SOURCE: what controls the speed of a range hood fan? ,
You will need to check inside the button contacts to identify if the control of current is by a series resistor or by the coil winding.
Since the high speed is working it is possible that the series resistor coil is open.So check for loss of contact continuity in the switch, if not you can use the present model of electronic fan controllers to give you a variable fan control. This can be connected to the main hi speed connection.
Tip: Identify the wattage and buy the regulator according to the specs.(42 inch type)
