Why dose my furnace go out at night by its self and not try to start it seams like it could be a roll switch if I take the cover off then push the black switch in it works fine for a while again and then dose it again with in a day what could it be??

Sounds like the unit is "locking out", and removing/replacing the access panel is interrupting/ restoring power and cancelling the lockout. Does the unit have a status LED behind a clear viewer on one of the front panels? If so, observe and note pattern (if any) of blinks next time the unit locks out. Do so BEFORE opening front panel.

Overheating,flame failure, are the two most common issues.

Check inside the access panels, or on the circuit board, for service legend.

The concord 80 + is olny about 4 years old

Three blinks usually means pressure switch code, but if you look everywhere on the furnace the codes should be listed somewhere. Neve seen won without them. They would also be listed in your instulation manual if you have it.
