I have a Bryant heating/cooling w/ heat pump - E3 error on thermostat and the house is 61 degrees and smells of burnt air


I asked Mr. Google " carrier e3 error code", and I found this.

The outdoor thermostat is in error, not connected, or shorted out. This code is displayed only if auxiliary heat and/or cool lockout feature is enabled.

What this means is that your o.d. unit has a component failure. The smeel you have inside is probably you electric heat elements that are energized. And if they haven't been energized in a while, its burning off some debris.

Carrier Gas Furnace runs fine randomly stops blowing LEDs flash


That blinking light may be the diagnostic light. Count the blinks next time it fails. Carrier units will have two different blinks depicting the error code such as one blink followed by a pause than 3 blinks giving you an error code of 13. Then look at the wiring diagram, it will have an error code chart telling you where to start with your diagnosis. You already know that if you remove the cover it erases the error code, so look thru the small window first.

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.

Error Code E3


I have the same type of Aprilaire humidifier unit with automatic temperature sensing control. My unit also displayed the 'E3' code. The HVAC technician was on site today and replaced the temperature sensing unit that is located outside the house. The humidifier is functioning normally once again.
