OEM Carrier Hot Surface Igniter for PG95SAS42100CBAA Gas Furnace

The hot surface igniter in your Carrier PG95SAS42100CBAA is the element that glows red-hot to light the burners at the start of every heat call. When the thermostat calls for heat, the control board energizes the igniter; it draws current, heats to roughly 2,000°F, and the gas valve opens onto the glowing element. Igniters are the single most common failure point in a 95% furnace because the brittle element is thermally cycled hundreds of times per season. When it cracks or burns out, the burners never light — you get the inducer and blower running but no flame, no heat, and after a few failed trials the board locks out and flashes an ignition-failure code. A failing igniter may also glow dimly or take far longer than the usual 17-45 seconds to reach temperature. This is a hot surface igniter. Silicon nitride elements (used in most current Carrier service kits) are far more impact- and thermal-shock-resistant than the older brittle silicon carbide style. A healthy 120V igniter typically measures roughly 40-90 ohms cold across its terminals; an open (infinite) reading means a cracked element that must be replaced. OEM matters here because resistance and glow temperature are matched to the board's timing. Generic igniters with wrong resistance either won't glow hot enough to reliably light gas or pull excess current that shortens element life and stresses the board's igniter relay. Install difficulty: 2/5. Tools: 1/4" nut driver, Phillips screwdriver, and a multimeter for the ohm check. Handle the new element only by its ceramic base — skin oils cause hot spots that crack it. SAFETY: shut off the gas supply and kill the furnace breaker before servicing. Ships same business day from our stocked warehouse on orders placed before 3 PM CST.

Compatibility

This part is compatible with Carrier model PG95SAS42100CBAA. Always verify the part number against your unit's data plate before ordering.

Why Choose OEM?

OEM parts are manufactured to the exact factory specifications for your unit. Generic aftermarket alternatives may fit physically but often use lower-rated components that reduce equipment life and void manufacturer warranties. When the cost difference between OEM and generic is $10-30, the OEM part is always the smarter investment on a system worth $5,000-$15,000.
