We just had a baby and our our AC stopped working.

Our carrier infinity system is throwing codes for.

71-thermal cutout low stage.

56- temp sensor out of range.

74- no 230v to compressor.

72- thermal cutout in high stage.

Anything I can check for?

Answer:

I'm sorry to hear that your AC system is not functioning properly, especially at a time when you have a new baby. While I can provide some general troubleshooting steps, it's important to note that HVAC systems can be complex, and it's usually best to contact a professional HVAC technician to diagnose and fix the issue. Nevertheless, here are a few things you can check:

1. Power supply: Ensure that the AC unit is receiving power. Check the circuit breaker or fuse box to make sure the circuit for the AC is not tripped or blown.

2. Air filter: A clogged air filter can cause various issues with the system, including temperature sensor problems. Check and clean or replace the air filter if necessary.

3. Temperature sensor: The out-of-range temperature sensor error (Code 56) indicates that the sensor may be faulty or disconnected. Locate the temperature sensor and check if it's properly connected and not damaged. If possible, try resetting or recalibrating the sensor according to the manufacturer's instructions.

4. Compressor voltage: The error code for no 230V to the compressor (Code 74) suggests a potential electrical issue. Check the electrical connections leading to the compressor to ensure they are secure. If you have a multimeter and are comfortable working with electrical components, you can check if the compressor is receiving the correct voltage.

5. Thermal cutout: The thermal cutout errors (Codes 71 and 72) suggest a potential overheating issue. Ensure that the unit has proper airflow by checking if the vents and registers are unobstructed. Clean any debris around the outdoor unit and ensure that it has enough clearance from walls or other objects. Additionally, make sure the indoor and outdoor units are not covered or obstructed in any way.

However, please keep in mind that these are general suggestions and may not address the specific issues with your Carrier Infinity system. It's highly recommended to contact a professional HVAC technician who can accurately diagnose and repair the problem. They have the necessary tools, knowledge, and expertise to handle complex HVAC issues safely and efficiently.
