SOURCE: Furnace Blower cycles on & off
check out the fan switch on the unit and make sure that its the correct one. it should cycloe on @ 120 degrees and cycle off around 100 degrees. Someone may have put in a different one and that is not the approve one.

There should be a reset button in the upper chamer next to the fan motor. In the middle ,push in on the center red button to reset it, this tripps because it says I,m not gettig enough air flow due to a plugged or dirty fliter located on the front cover or door.

Hi, you first of all replace the thermostat which can sometimes be the cause of the clicking noise. Since you have changed the limit switch and the blower motor, consider changing the thermostat to see what happens and if the clicking continues, you have no choice than to change the circuit board..

Hello, have you checked the orifice or gas tube for any blockages? Sometimes dust and spider webs can block the flow of gas.
