1. A cooking appliance comprising:
a first burner of a cooktop having a burner head, flame slots extending through the burner head, and a burner cap on top of the burner head;
a first sensor located proximate to one of the flame slots;
a processor receiving a first electronic input from the first sensor;
a first valve providing a valve input to the processor, the valve input is related to a valve position of the first valve, said first valve located intermediate the first burner and a gas supply selected from propane and natural gas; and
a second sensor proximate to the flame slots of the first burner, said second sensor directing a second electronic input to the processor;
wherein the processor evaluates a burner performance characteristic selected from the group of least one of flame level, temperature rise, time lag, and temperature level using the first electronic input compared to an anticipated performance characteristic of the first burner based on the valve position of the first valve; and then provides a first burner performance output to a user identifying a condition of the first burner; and
wherein the first sensor is located internal to the flame slots.
