I have an American Standard gas furnace (approx 10 yrs. old) that has a slight case of delayed ignition lately. I have only removed the flame sensor to scuff off the buildup and brushed dust out of the burners (after removing them), but those are the only parts I have touched and after putting the burners back it seems there is a slight delayed ignition which causes a sound as the gas ignites. I know this is probably not a normal function but everything was put back exactly as it was before removal so I don't know what else could be causing this issue. I've read about it as much as I could find but mostly old burners are mentioned as the cause and that replacement would fix the problem. This didn't exist before I took them out and cleaned the dust but I thought maybe someone would have some suggestions. The burners look fine as far as I can tell, the HXs don't appear to have any cracks, and the filter is changed regularly. Anything else I can check (with a meter, etc.) to figure this out? Thanks for any help.
