If your furnace isn't kicking on right, or it's cycling too much, a bad limit switch could be the culprit.

This is a brand new, generic replacement switch that's designed to work with many Goodman, Amana, and Janitrol furnaces.

It's the L150-45F model, which directly replaces the older part number B1370115.

The part number on this specific piece is 3692.

It's a safety device that monitors the temperature inside your furnace, so getting the right one is important.
