I have a Bryant Gas Furnace. From the sticker, the furnace was made in 1991. The model number is: 373LAV036055.

The furnace has electric ignition.

When turning thermostat from off to heat, the following happens:

1. small fan starts and 10 seconds later I hear a faint relay click
2. Relay clicks and gas releases
3. Small relay click 20 seconds later
4. Relay clicks and gas releases
5. Small relay click 20 seconds later
6. Relay clicks and gas releases
7. Small relay click 20 seconds later
8. Furnace stops attempts and never attempts process without me toggling thermostat.

Please help ASAP. Interior temps were 65 Degrees Fahrenheit last night.

 

Appears the culprit is the igniter.



How can I source one of these ASAP as a consumer?

Model: Norton 271M

Link to site selling one: Online ordering - Hot Surface Igniters

 

You should be able to get that from almost any HVAC store or maybe even an appliance parts place.
