Carrier Weathermaker SXI Model 58SX8100LG Code 12

When I wake up in the morning the furnace is out and Code 12 is flashing which is blower calibration lockout. I turn off the power which resets the computer and the unit restarts and runs fine but the Code 12 reappears and it goes out again.

The unit is 19 years old.

What do you suggest?

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.

    Look inside the door for a legend of the codes. I don't remember what a 44 is but seems Ive seen it before.

Heat exchanger replacement for carrier weathermaker 8000


After 18 years of service, it is not cost effective to just replace the heat exchanger. Go the complete replacement route. There may be a utility company incentive to do it.

Code 24 on carrier weathermaker 8000ts


Turn power off to unit. Open air handler and take a picture of the low voltage (tstat) wires and where they are landed. Remove all thermostat wires from control board. Then replace the 5 amp fuse that is likely on the board. Fuse likely looks like one for a car (blade style). Put a jumper (small piece of wire) from the R terminal to the G terminal and turn power back on to unit. This should bring on the indoor blower. Let me know how that goes!!

I have a carrier 58RAV050-12 and my furnace won't turn on. It was working earlier today but it just stopped. Any suggestions as to why?


Check the pilot lt. If its out shutdown your furnace and call a repairman. If the pilot light is on, the flame sensor might have gone out. It's a long silver sensor that sits in the pilot light flame and senses when the flame is present. If it isn't working the furnace will automatically shut down.

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.

I have a Carrier Weathermaker SXi. Furnance will not turn on. I shut power off and waited ten minutes and tried to restart. Codes flashing are 12, 31, 32, 33, 41, 42. Can this be started in emergency mode?


Emergency heat is made for this kind of situation.So yes you can.
now for the codes.
code 12= Blower on after power up
code 31=High heat pressure switch or relay didn't close or reopened
code 32=Low heat pressure switch or relay didn't close or reopened
code 33=limit circuit fault(Flame rollout switch is open)
code 41=board fault
code 42=control lockout

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 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
