Termostat fan was set to ON.
I set the termostat to HEAT and FAN option to: AUTO.

Now it's not doing anything. Pilot on our furnace is burning, but
burners are not ignited.
What could be the reason for burners not igniting?


Thermostat is in the proper position. The pilot is heating a thermocouple
that says it is OK for the main gas valve to open. If the thermocouple is
bad, the heat will not go on. It is a safety device to assure the gas
valve does not open with no way of igniting the gas. They are generally
cheap and can be found a good hardware stores and home centers.


Are you suggesting that his thermocouple is bad?
