Carrier Heating & Cooling - Recent Questions, Troubleshooting & Support

Well without a model number, I can tell you this. On some models, F3 indicates fan speed 3, which is high speed.If you push the mode button, these units will switch between f1, f2, f3 and smart fan. No problem.
On others, F3 indicates a fan speed error, either something is keeping the fan from turning, or there is a bad or loose connection somewhere.
On still other models, F3 indicates a freon leak or problem in the refrigerant circuit.
If carrier made their own units, they would probably act the same, but they don't. Model number is important, since the unit could be a daikin, LG or Samsung under the skin...

FF code means blown or missing damper fuse. Replace damper fuse (inside equipment cover plate) and try again. If damper fuse blows again, find and fix the problem causing the fuse to blow.

-When a blinking light problem occurs, your air conditioning system often shuts off too, meaning warm air is blown. You can switch off the circuit breaker of your AC unit, wait for a few seconds, and then switch it on again. For some, the unit will start working normally again.

Do you have the model number/serial number?

Carrier Heating... | Answered on Feb 15, 2020

The limit switch on the inducer has tripped. There are two wires that go to a small disk about the size of dime that has a small button in the center. Push this little button and you will feel a littl snap and the unit should fire up. Check all the manual reset limits as well. If the unit still won't start, jump the two wires by bypassing the limit switch. If it starts, then replace the switch. Bypassing the switch is only temporary and could lead to death if it is used as a permenant fix.
