I pressure fan speed 1 button on front of cooker hood. was loud bang & nothing works. Looking inside hood behind where the on/off & fan speed Control Board PCB holding the bulbs is & the glass part of one bulb had totally blown off. Please let me know if the Control Board PCB in the hood has a fuse inside that may have blown or is the fuse located in main PCB located in the Chimney Hood ?
