This is a gas furnace Luxaire TG8S080812MP11A about 10 years old. For the last three mornings this furnace has been blowing cold after pulling temp up just a couple of degrees. When I cut pwr to unit and wait a minute, she behaves normally and will be good for the rest of the day maintaining 68F, but it's that temp pull up from an overnight 63 to just 68 (930pm--0646am) that messes something up. What do I do to fix?

What error is it failing on?
Cycling power is resetting the error that the furnace is off on.
What is the model number of the furnace?

It’s likely a limit but we need to be certain.
What air filter are you using and is it clean? All vents open in the house?

For the sake of doing SOMETHING, I removed the panels, blew some compressed air to dust it out, polished the flame rod with emery, changed the filter and harvested a pound of cobwebs. This morning the unit is behaving normally. I wish I knew what it was I did that helped.

When was the last time your furnace had a preventative maintenance?
This equipment needs yearly maintenance to run properly.
