Emerson 768A-845 Hot Surface Ignitor - 80V Silicon Nitride Furnace Ignitor

About This Product

If your furnace isn't igniting and you're hearing the click but no flame, this Emerson hot surface ignitor is likely what you need.

The 768A-845 model is one of the most common replacements for residential furnaces, and the silicon nitride construction is more durable than the older ceramic types.

It's an 80V ignitor with those white Teflon-coated leads that resist heat damage, and the 2-terminal AMP receptacle makes installation pretty straightforward if you're comfortable with basic electrical work.

The key is handling it carefully - these things are fragile before installation, so no dropping or rough treatment.

The replacement process usually involves just a couple screws and electrical connections, but definitely turn off power at the breaker first.

Once installed, it should glow bright orange when the furnace calls for heat, then the gas valve opens and you get ignition.

Having a spare on hand is smart too - when these fail, they usually do so without warning, leaving you without heat until you can get a replacement.

The quality is OEM-grade, and it's compatible with many furnace brands that use this style of hot surface ignition.

For the price compared to a service call, it's worth learning to replace yourself if you're handy.
