Welcome to Just Answer, my name is ***** ***** I will do my best to help you with your issue. First I’ll need some more info so I have a more complete picture of your situation.

What is the flash code on the control board LED?

Would that be the ds1 led?
HVAC Technician: Rick, HVAC Supervisor replied 7 months ago

I never noticed any LED designation. Do you have an LED that's flashing a sequence?

It's staying solid
HVAC Technician: Rick, HVAC Supervisor replied 7 months ago

Steady on is normal operation. If the furnace isn't doing anything try this; jump the R & W terminals on the thermostat terminal strip on the control board. Then power it back up. Does the draft fan run?

The fan runs
HVAC Technician: Rick, HVAC Supervisor replied 7 months ago

The draft fan runs and you have no heat and a steady on LED? If so cycle the power off wait a minute then turn it back on. Tell me what happens.

The igniter lights up for around 11 seconds then shuts off, and there is no flame
HVAC Technician: Rick, HVAC Supervisor replied 7 months ago

Ok, you should be getting a failed igniton flash sequence. You need to test for 24 volts AC at the gas valve when the igniter is glowing.
