Need more information. OK, I will assume that the thermostat is set to heat and is set above current room temperature. First thing to try is switch the thermostat selector switch to off wait at least one minute switch it back to heat. If nothing happens check for a flashing light. Don't open or remove any panels at this point. Look for a little window on one or both cover panels on the front of the unit. Look for a steady or flashing light. If there is a flashing light (or two, some have more than one) count the number of flashes and remember or write them down. This is a fault code and will tell you what may be wrong with the system. Look for a decal on the unit that lists the flash codes and what they stand for. If there is not a decal on the outside of the unit look for the owners or service manual. There will be a page that will define the codes. Failing that shut down the system and take off one front panel at a time and look for the decal. Make note of the definition. If the fix is other than something very simple call a certified technician to have it repaired there isn't a lot that the do-it-yourselfer is able to do without specific tools and information. If you have the covers off if your unit has a small blower unit on the front that connects to a plastic or metal flue pipe that leads outside this may be the culprit. Very carefully try to touch the motor housing. If this motor is stuck it will be VERY HOT so don't just plop your hand on it or you will regret it. Without having more information that is about the best I can do.

Carrier super saver furnace keeps going on and off


Sounds like the flame sensor is dirty or bad. This sits in the burner flame when the burners are running. This usually has a single white wire connected to the back of it.

Gas valve lockout


It means that the furnace isn't igniting and for safety the control board is preventing the gas valve from opening. Turn off the power to the furnace for a few seconds then observe what the furnace does in heat mode. Some furnaces will run the blower for a minute after you power it back up. After that see if the furnace tries to come on. If you are still getting the code then one of you high temp limit or roll out switches has tripped. Now is the time for a service tech. Make sure that you check you filter and air flow too. Low air flow means the furnace may be over heating.
The other thing is the hot surface igniter. Look closely at it with the power off. Do you see a white spot on the element or a crack. If so the HSI is bad. It's an easy replacement but DO NOT touch the carbon element with your fingers and be very careful handling it as it is EXTREMELY fragile.

Furnace runs OK, but blower runs again a few seconds later


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.

Furnace runs but won't ignite.


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.

Carrier Weathermaker SX model 58SX060-CC Blower runs all the time


Remove all power from the furnace, it is likely the brain in the furnace is need of being reset, from the battery replacement, why did you change the battery, was there an indicator telling you to change it?

Many times just removing all the power to the furnace will do the trick with a reset, if not let me know and we will go from there, but it sounds like the main brain is confused or bad, more likely confused, so try the power removed first.

Than let me know wbwill@sbcglobal.net

Contact the company that installed the unit. Its new, under warranty, Anything you do could void the warranty.
