What is the maximum amp draw for a 120v hot surface igniter?

In the context of hot surface igniters (HSIs) used in gas heating appliances, the maximum amp draw generally falls within the range specified for performance and operational efficiency. For a 120V hot surface igniter, the maximum amp draw is typically around 3 amps. This level is important for ensuring that the igniter can initially heat up adequately to ignite the gas without exceeding safety and operational limits of the appliance or causing undue stress to electrical components.

Hot surface igniters require a certain level of current to generate sufficient heat, and at 3 amps, they operate effectively for most standard applications while remaining within the design specifications of the equipment. Understanding this allows technicians to choose appropriate replacement parts and diagnose operational issues, ensuring safety and optimal performance in gas appliances.
