I would say that the relay switch that takes the signal from the thermostat to the furnace is almost gone. When the house temp. comes down to where you have it set, the relay tells the furnace to come on. If that switch is faulty, it could make the furnace turn on & off too often.
I hope that helps.

don't you love smart aleck answers. The intelligence is just oozing.
Take the cover off the thermostat. You will see a round dial with a metal tab. the round dial will have numbers in increasing order clockwise. This is the range of cut on/cut off. You want that number to be as high as possible, or maybe a little lower.
So, let's say you have it on 68 with the range of 2 degrees. The furnace will not cut on until 66, but will cut back of at 70.
Not sure if all thermostats have this.....
Also, make sure the mercury glass is reasonably level.

I assume that you must have forced air and not a hot water radiation system? If it is a radiation system and it is kicking on and off...you need to call a service man soon. If it is a forced air system....you need to call the service man to have the thermostat adjusted. It can be adjusted to change the range of temperature that causes the furnace to kick on and off. If the range is too small, the furnace is constantly going off and on.

If you had said what kind of furnace, it would be easier to suggest remedies, but if it is a gas- or oil-fired unit, I'd guess a limit switch is opening for some reason, and then reclosing when whatever tripped it goes back to normal. Could be a bad (marginal) limit switch, too.
A dirty return air filter can cause the plenum high heat limit to trip, if it's a hot air system. That's a common cause of "cycling".

Propane, like organic gasoline furnaces have flame protection and flame proving gadgets which will close down the unit in the event that they the two do no longer sense flame in the wonderful place and could close it down in the event that they sense flame in the incorrect place. Over & above that, your furnace calls for each year cleansing and repair. (some require it to enforce the guaranty) call a propane qualified service outfit to furnish your gadget a iciness music up. Your life is worth around $seventy 5 bux, staggering?

usually this happens because of air restriction,...dirty filters, dirty evaporator coil, possibly blower moter is weak or wrong speed. what is happening is the furnace is heating up and air flow isnt sufficient so you are tripping limit switches. i recommend a professional tech.

You have a temp setting...when the heater heats the area to the desired temp..it turns off so it won't get hotter. When it cools down, it turns on so it won't get cooler...GET IT??
