Clare CHU 072 NH3A problum
I have a Clare model # CHU 072 NH3A Natural gas furnace that has run mostly problem free for the last few years. Last winter the furnace would cycle but no "whoosh" and no heat. Called repairman and they changed a "vacuum pod looking thing in the front and away we went. Worked great all winter. Then in the summer we used the central air with no issues. Tried to turn on the heat this fall and again it is cycling with no start up and no heat. Any Ideas?? thanks.

Check to see if the vacuum pod(pressure switch) is closing.

yes it makes a clicking sound when you apply vacuum or blow you here a click sound and a click sound comes from somewhere inside near the upper part of the furnace. But still no whoosh sound or heat. Thanks anyways. :)
