Customer Question
I have central heating...

I have central heating in my home. and a Lux thermostat. I turn off the heat at night and turn it on in the morning. As usual this morning I turned it on with the temp in the house at 58 and set the temp to 70. No heat came out of the vent just air. I waited and reset the thermostat but still no heat.

Contractor's Assistant: Did you double-check the thermostat's settings? And what about the filters?

Filters have been cleaned in Sept of this year. Thermostat setting was overridden to 70 degrees bec. temp inside house was 58. Mode- ON -HEAT

Contractor's Assistant: Do you plan on doing the work yourself?

Trying to find out what is wrong first.

Contractor's Assistant: Anything else we should know to help you best?

Air conditioning is working.

HVAC Technician: airheatman, HVAC Technician replied 2 months ago

Can you give me complete model from inside furnace in burner compartment so I can provide guidance with this specific unit.Model will be on a label just above burners on right or left inside panel

Then look in blower compartment and see if we have a control board with a blinking light.If so tell me the pattern of that flash.That will indicate what is wrong and tell us where to start troubleshooting.

I am at work right now so I can't do it on real time. Control Board is under our house.
HVAC Technician: airheatman, HVAC Technician replied 2 months ago

Will you have internet access when there?

HVAC Technician: airheatman, HVAC Technician replied 2 months ago

The control board will have an led flashing to tell us what has failed. For example if issue is an open limit we may get a 4 flash code or if pressure switch is issue we may get a 3 flash code. I can look it up bu model.There may be a legend on furnace telling us the flash code and that will tell us what direction to go in troubleshooting.
