Emerson Climate Technologies White-Rodgers Hot Surface Ignitor 120V

SKU CH-NSYG-7F7WY

Silicon-carbide hot surface ignitor for LP or natural gas systems at 120 volts with spiral tip and mounting block

  • Silicon carbide element resists thermal shock for reliable ignition
  • 120 V operation matches standard furnace and boiler supplies
  • 5-1/4 in. overall length fits common mounting brackets
  • Spiral tip design increases surface area for faster heat-up
  • Includes mounting nut, spring clips and PG9 adapter for quick installation

Hot Surface Ignitor 120V

The White-Rodgers hot surface ignitor operates at 120 volts and uses a silicon carbide spiral tip to light LP or natural gas systems. It is built as a direct replacement for M-style mounting blocks in heating equipment.

Included Mounting Hardware

The package supplies a mounting nut, spring clips and a PG9 adapter sleeve so the ignitor secures to the existing bracket without extra parts. Armored cable leads measuring 36 inches with split-spade terminals simplify the electrical connection.

Simple Swap Installation

Installers remove the old ignitor, fit the new unit using the supplied clips and nut, then attach the spade terminals to the control board. The low-mass tip reaches temperature quickly, reducing the chance of delayed ignition on startup.

Questions about this item

How often will the silicon carbide hot surface ignitor need replacement?

Silicon carbide ignitors typically last several heating seasons before the tip degrades and requires replacement.

What is the first limitation that appears during continuous furnace operation?

The 120 V spiral tip reaches its maximum surface temperature quickly, so sustained cycles are limited by the element's heat tolerance.

How much heat and noise does the ignitor produce when the furnace runs all day?

The ignitor itself is silent and only radiates heat during the brief ignition sequence; it adds no continuous noise or heat once the burner is lit.
