Question from user rbfking at hvacadvice at reddit.com.


Answer:

Do you have a multi-meter? Is there 24 to 28vac between the W and R terminals. If not, then you need to see if the furnace has 24vac at the R and C terminals. If it doesnt the furnace may not have power, or the transformer making the 24vac power may have failed.


A standing pilot can stay lit while the furnace loses power. Once the pilot light heats the thermopile, it will keep the pilot valve open indefinitely.
