Try to see if the limit switch has a reset push button in the center of the back of the switch. If not you will have to replace the switch if defective. The switch tripped for a reason. There is a wiring diagram on the back side of the blower door to assist you with finding the switch.

Make sure of these.

Air filter new or clean

All registers open

Cold air returns not blocked

If the problem persists you may have to call for professional On Site service.

I will not be able to post back right away since I am leaving but I will check your post later in the day.
