Smile furnace keeps kicking on/off

my old honeywell gas furnace keeps kicking on and off every 5 or so minutes even when the wall thermostat isn't below what it is programmed to kick on at is this a problem with the thermostat on the furnace itself?

It can be a numbers of things.

The burning going on and off while the blower stays on whole time?

or

Burners are going off, then blower shuts down and starts over?


How is the air filter?

I just replaced the air filters, burners are going off then the blowers shut off then about 10 minutes later it fires right up again even though the wall thermostat is set at 63 and it is 65 inside

Does the furnace fire off when the t-stat switched over to off?

Is there a hole in the wall behind the t-stat? Maybe it's has a small draft to give the t-stat a faulse reading. Pack the hole with insulation.

Make and model of the t-stat?

It almost sounds like it's the t-stat.
