Emerson Thermostats 768A-815 Hot Surface Ignitor

Excelente funcionamiento, maximizó la potencia de la flama

There was a marking on my existing ignitor, D343692. This ignitor is identical to that, the connector and metal bracket are a perfect fit. I would say it's the equivalent to IGN00145 / D343692. Works in my American Standard (same as Trane) furnace. EDIT: the ignitor failed after 2 months

The hot surface ignitor (HSI) is an important part of your gas furnace that can fail. The way the HSI works is that it is heated to a high temperature. When flammable gases come in contact with HSI they ignite and generate heat. How do you know if HSI is working? The HSI heats and when it does it glows. It glows brighter that a 40 watt incandescent lamp filament. And you can see this from the glass hole. If you don't see the glow before the furnace fires up, perhaps this part has failed. I replaced mine as part of preventive maintenance. The last one was nearly 6 years old, still going but the ones before had failed every year or so. Every time it failed it was $300 to the company that replaced it. This time it was much less with the Emerson clone. It took about 10 minutes to get the job done. I have the old one still saved up in case this fails and I have to order another one. All in call happy with the purchase. How long it lasts is another story.

Used this to replace a White Rogers 768A-15 and worked perfectly. We had a tech from Atlas Trillo come out and told us the ignitor was bad and quoted $2300 to replace it and the gas valve but recommended we buy a new furnace as 'the ignitor was difficult to get and even if we replaced that there would probably be other issues in the seven stage ignition process'. Well there were other issues, he had unplugged the High Limit switch so after I replaced the ignitor I had to reconnect one wire to that which had been removed and tucked behind another part before the burners finally lit. There was no issue with the gas valve and I've no idea why he wanted to replace it.

This fixed my gas furnace problem. It replaced my prior ignitor 768A-15 that measured 1.6 k-Ohms, indicating a fault (and it also wasn't working). Before installing I measured a resistance of 16 Ohms. It worked upon turning on my furnace and having the thermostat call for heat, successfully igniting the gas into flames for my furnace.
