Hi, this is a code telling you that something on the furnace has failed. You will have a chart with a list of codes and the amount of blinks fast and slow that will tell you what the problem is and what you can do to solve this. The chart may be glued to the panel, or on the control module it self. The code might be a 33. It might be a roll out switch has tripped and needs to be reset, or what ever, you will need to look for what it is saying. To reset when you find the problem, unplug power or shut off breaker, and turn back on in a minute or 2.Let me know the out come.

I have a Carrier Infinity 96 gas furnace with no heat


That means that the furnace is throwing a code to trouble shoot whats wrong. Most of the time, furnaces will have a code list on the inside of the door cover to explain what each code means, some of them don't. Its hard to say what it could be without knowing where to start. However, answering a few questions with someone knowledgeable over the phone if possible could help speed things up, but it would involve you being at the furnace and seeing what happens before it throws the code. If you do have a code list, this would help tremendously.

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.

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 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).

Carrier Infinity Control Thermostat SYSTXCCUID01-B


Your old stat is wired for a traditional thermostat and not a communication stat like the new infinity you have. There is a module plug on the furnace board that will need to be connected to the new thermostat for it to work. The wires that are wired now are from a terminal strip inside the furnace. Please contact your local Carrier dealer. They may be able to get that harness for you
