Can you give me the complete model number on the furnace?

If furnace is not coming on or does not stay on , there should be an error light flashing on the control board in blower compartment to indicate what has failed. If you can locate this and tell me the pattern of the flash, that will point us in the right direction for troubleshooting.
Also let me know if you have a multi meter for troubleshooting.WE will go from here.

I'm not home at the moment. But I dont remember the light flashing. But I can check it later, is there codes you can send me?
Customer reply replied 7 months ago
I Just had my wife check for flashing light, it stays green. Could it be just batteries in the thermostat?
Customer reply replied 7 months ago
I will change the batteries in the thermostat and try it later.Thank you!
HVAC Technician: airheatman, HVAC Technician replied 7 months ago

If it is thermostat, it should not start but lets change batteries and see, You can also bypass thermostat by jumping R and W on furnace board to see if furnace will run.https://i.imgur.com/JprQdYv.png
