A range hood with features for monitoring the temperature of a cook top located below it is provided. In one example, the range hood includes one or more temperature sensors positioned over the cook top for measuring temperature of the heating elements below. If the measured temperatures(s) exceeds one or more predetermined temperature levels, either with or without a time delay, a notification and/or other remedial response is provided to a user of the appliance. The notification can be, for example, a visual warning projected onto the cook top and/or an audible alarm. Different warnings can be provided based on different temperature levels as measured by the temperature sensors.
