Yes, many residential kitchen range hoods feature an internal thermal fuse or inline electrical fuse designed to protect the blower motor and control board from overheating. When excessive heat from the cooktop below builds up inside the range hood housing, this thermal fuse melts and breaks the circuit to prevent electrical fires. You can troubleshoot power loss safely using a digital multimeter set to continuity after unplugging the unit. You can verify that your corrective action is successful when testing continuity across the fuse and replacing a blown thermal fuse restores full electrical power, lighting, and fan operation to the range hood.
