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.

If you're sure the igniter is good and the controller is sending voltage to gas valve to open, but not to the igniter then, yes, the controller is bad. The only way to know for sure is to remove the igniter's molded plug from the board and test voltage directly at the board. You should get about 100-120 vac to the igniter.

It says RW closed. How can I fix it??


This is the roll out switch located on the burner. Its a small disk with 2 wires and a small button in the middle. Depress this button to reset.

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.

Carrier Weathermaker SXI Model 58SX8100LG Code 12


Code 12 I believe is power up after power off and a call for heat from the the thermostat. If you have a weak door switch that may be vibrating and going on and off it would cause this as would any thing that causes the power to drop low or out then reapply its self. try holding the door switch in while watching the board and after 2 or 3 minutes the furnace should go on to lite and the blower cycle off. If it stays in this mode try turning the thermostat off (heat - OFF -cool) and then push in the door switch nothing should happen except the lite on the board come on and stay on. If it does this than have someone turn the thermostat to heat and see if it starts or put the door on and set the heat and see if *** goes through the normal cycle of heating. If however it goes right back into the blower mode and shows the 12 code your problem is still with you. So next remove the wire on the "W" terminal on the board. Retry power to the door switch and now nothing should be on except the red lite. If it tries to start the 12 code and blower up again Im pretty sure you have a bad ignition/blower control board.

Furnace wont run


First of all when you flip the switch, it goes thru a startup sequence. THEN it turns on the Igniter (notice the red glow). Then the gas turns on.

Now at this point check the idiot light and it should be giving you a code of 34. That 34 (3 shorts 4 longs) says that there was a problem igniting the furnace. After it cycles thru at least 4 times and fails to ignite all the blowers, then is when you get a code 14 (1 short 3 longs)

NOTICE what's happening with ALL the burner Tubes each time it attempts to ignite. If only one or two are running....then this is your problem.
To fix all you do is take out the burner Tubes, look for debris, blow them out (blow from the front where all the jets are), and replace them in sequence from left to right (the tabs overlap).

(HVAC) Furnace Not Igniting Quickly


Make sure a back draft in the flue is not happening. Wind can blow it out until the flue heats up. The flame sensor may not be close enough to the burner flame. It may be weak and need to be replaced or if its an optical one it may be dirty and not see the flame very well. Its not wasting much gas but it puts extra wear and tear on the gas controls, is noisy, and, as you said, blows cold drafty air. A gas control system that has issues of any kind is not real safe. It needs to get fixed.

Carrier 58MVP; Blower on, no heat. Themosta at 75, temp at 69 and furnace still does not come on. Fault code 12


A code 12 is "Blower on after power-up" Try resetting the furnace with either the Emergency switch or circuit breaker. If it continues, you may need a new control board.

Carrier Weathermaker gas 8000 will not ignite


Your hot surface igniter may be bad. It may be cracked which would prevent it from starting the burner flame.

Carrier furnace weathermaker 8000


. Several times of recyling power normally brings the furnance up. Though the failure code has always been 31, there are several different behaviour when the blower starts after reset :
a. blower simply creases.
b. there is an attempt to start the heating unit (I hear the high pitch noises), then everything stops.
c. there is an attempt to start the heating unit (I hear the high pitch noises), once I see the orange glow from the coil, normally the gas is lit up and the unit starts working.
