Is it possible the drain is plugged? The newer furnaces have a moisture drain and will shut down if they are blocked., shutting them down and restarting will reset fault, but will come right back if not fixed.
I need a little more info I feel certain I can solve the problem I need to know a couple of things. 1- Model # of the furnace, take off the top door look to your right or left you will see a little metal data plate on the top of the plate you will see the model # If it is a horizontal furnace the data plate will be on the same side the controls are on . 2- Is the furnace a natural gas, LP gas, fuel oil or electric? 3- Does it do this when the temperature is above freezing? 4- If you could list the parts replaced it would be helpful. A furnace properly maintained can last upwards of 25 years.
There is a pressure switch near your draft inducer motor that needs to close when draft inducer motor is running. Verify that the switch is closing. If it is not closing, you might have a problem with either the switch itself, or there could be some sort of blockage in your flue. I would start with the switch first. This switch has to "prove" before it will allow anything else to happen. The loud click could be from your switch or your gas valve. If the switch is closing and nothing else is happening, it could be a problem with your gas valve or HSI.
Could be a defective thermostat in the plenum.
When a gas furnace shuts down the fan(blower) will run until the plenum cools to the safe range. Usually 1 and 1/2 minutes.
Intermittent operation is a defective thermostat or relay.
Error code 12 is blower on after power up. Meaning: after you turn on power to the furnace for aprox. 60-90 seconds the blower will run. The blower should then shut down and the furnace should go through the start up process, providing that the thermostat is set for and calling for heat. If the furnace fails to start after blower shut down there should be a new fault/error code. However if the blower continues to run longer then 90 seconds and continues with the same fault code more then likely the circuit board is bad. Please let me know if this was helpful and give me a rating. Good luck.
SOund like you heating element has a open limit or the sequencer is bad. Another thing that it may be is the element wire has broken. Either way it sounds like you need a technician to come out and repair.
Hi and welcome to Fixya. I believe that the wind is affecting the draft. What I would recommend is to install a cap on the flue that is similar to a weather vane in that it rotates to block the wind from creating a downdraft in the flue. Some times depending on the direction and strength of the wind it will come up over the roof peak and then down the flue. A regular fixed cap may work too. You should be able to purchase one at your local hardware store. Please let me know if this was helpful. Good luck.
