JA: Thanks. Can you give me any more details about your issue?
Customer: I went up the ceiling and I can see the furnace glowing but it turns on and off. the red light is on steady

Turn off power to furnace and then back on. Go in attic and observe. Sequence. Should be that the small fan starts for a few seconds,ignitor glows for 10 seconds and gas valve opens. Watch and let me know if gas valve clicks. Russ

I turned it off and on, the fan turned on for maybe a minute then it glowed then I heard a click followed by the burner fired, all of them and it kept goin. I set the thermostat to 75. When the thermostat reach 71, the hvac stopped even the set temp is 75. Usually it doesn't stop until it reach the set max temp.
Customer: replied 1 year ago.
But It still blowing heat though, I check each vent and warm air coming out, but the temp doesn't go up higher than 71

Check the filters to see if they are blocked. If so replace. When this goes off check the flashing led at fi=urnace and count the flashes. This will tell us the problem area. Russ
