1. sounds like the control board. i cannot confirm this as i am not able to come sit in front of your furnace. please have a tech come to sit in front of your furnace and figure it out!!

Hi check out the pressure switch clean the air filter and check out the fan control see if this is clean

small dual gas turbine and use electric heating and supplies your home also ....

Sounds like a bad thermostat or stuck motor control relay. Turn off the breaker at the unit or in the electrical panel to kill the motor and see if cutting power, if relay is bad, cycles off and stays, but you should leave power off and call for service right away.

There is a switch, activated when you open the service panel, that kills most power to the unit, including the DI Blower motor. Your furnace should also be equipped with an exterior kill switch, or there's always the good old breaker box. Good Luck!

Check the relay for that motor. Follow the wires back to locate the relay. If the relay clicks when you advance the thermostat then check the relay contacts with a multimeter. If there is continuity and a low resistance value on the contacts then look at the motor itself. There is a hi limit safety klixon switch that may be holding voltage from reaching the motor too. The wiring diagram should be on or inside an access panel.

The "mother board" or integrated control module is essentially the brain that controls the sequence of operation in your gas fired furnace. It is located, generally, in the blower compartment. That is the bottom of the two compartments of the in the furnace. It looks like a circuit board with all the wires of the furnace leading to it.

What Light???? More informaton needed.

I would first check the blower to be sure it is ok. If so then the control board would need to be replaced.

Does it run if youn pull the thermostat from the base?

Thermostats go for 20 to 40 bucks at Home Depot . You may need to make the investment.
