Good Morning. I am Kevin, one of the tech's here on JA.
Can I get the model number of your furnace?
you should find that label in the burner compartment
there should be a letter, number then three letters. such as g9mae,n9mse.
is there a pattern with short flashes, followed by a pattern of long flashes? If so, can you read those?
ok, in the burner compartment, with the service switch to the furnace shut off, I want you to find a small device with two wires connected to it. There may be two of these, they are usually located "just above the burners" where you can see flame. In between these two wires maybe a reset if it is a manual reset. See if you can locate these. I cannot tell you much without a good model number, the c9, doesn't show me anything either.
did you get a click or anything when you depress the button in the center between the wires?
have you retried the furnace?
so we have ignition?
have you had very high winds?
is your blower running at all?
do you have a "fan on switch" on the thermostat?
turn to on, and allow to run, does the blower continue to run without any problem?
do you have air conditioning as well?
ok, with the fan switch on the thermostat in the "on" position, you should have air blowing from the vent's.
ok, this could be your problem. We need to go to the furnace now. problem is in the furnace, most likely in the blower circuit.
do you have a service switch on the side of the furnace?
great, remove bottom panel...........
accessing the blower compartment
carefully, place your hand near the motor (follow the wires going to the blower motor), if you start feeling heat, don't get any closer, but if you don't see if you can touch the motor...... is it hot?
then now we need a volt meter to test....... do you have one or do you have a friend that has one, and knows how to use?
It sounds to me like you have a defective relay on your circuit board. what needs to happen on these boards, is a call for heat, (low voltage section through limit switches, high limits, pressure switches), back to the board to send power to the gas valve. All this is usually a "timed cycle", after that "timed cycle" has been reached, a relay on the board, turns "high voltage" power to the fan motor. This does not appear to be happening based on what you are telling me. The blower motor is not running. This will trip the high limit in the circuit, and never allow the home to heat, because you are not moving air over the heat exchanger.
