I have a inborn gas furnace, and a programmable thermostat

I lit the pilot light and set the thermostat for 70 degree and the thermostat kicks the burners on but nearby is not any nouns blowing out of the vents contained by any of the rooms in the house. The solely way the roast comes out the vents is if I stir to the thermostat and turn the fan from auto to on. Please support

Note: Every year past I would enjoy the thermostat set to "Heat", and the fan on the thermostat set to "Auto" and the radiator would automatically kick on until it reach the set temp and then it would automatically see off. Dont't know why it wont this year.
Question almost septic reservoir?
Answers:    If you hold an older furnace next to a fan cut-off date switch and the t-stat is wired to control fan consequently you also have a "enthusiast relay centre" this will allow the blower to run at multiple speeds and has a relay surrounded by it that is not repairable. You would hold to replace the whole relay central part. If your furnace is newer and the t-stat is wired for fan control after the control board on the furnace controls the fan. When you put it to "ON" it will typically come on at cooling speed or glorious speed. There is a possibility the low speed relay on the board is toast or the low speed winding on the motor is inconsistent. Probably gonna have to draw from someone in to look at this one, I could find the problem contained by a couple minutes if I were nearby to look at it but i can't see what your looking at. Good luck
Why is in attendance a long hitch beside...
it is probably not working because of a impossible relay.
