A Whirlpool air conditioner displaying error code “22” usually indicates a problem with the indoor fan motor. Here’s a breakdown of what that typically means and what you can do:
Possible Causes for Error Code 22 (Whirlpool Air Conditioner):
- Faulty Indoor Fan Motor: The most likely cause is a malfunctioning indoor fan motor. This motor is responsible for circulating the cool air throughout the room. It could be failing due to age, wear and tear, or electrical issues.
- Wiring Issues: A loose or damaged wire connection to the fan motor or the control board can cause an error. This could be a broken wire, a corroded connection, or a wire that has come loose.
- Control Board Malfunction: In some cases, the problem might be with the control board itself. The control board sends signals to the fan motor, and if it’s malfunctioning, it might not be sending the correct signals or detecting the fan motor’s operation correctly.
- Capacitor Issue (for models with capacitors): Some older Whirlpool AC models use a capacitor to help start the fan motor. A failing capacitor can prevent the motor from running correctly.
- Obstruction: Although less common, check if something physically obstructs the fan blade inside the indoor unit. This could be debris, a foreign object, or a bent fan blade.
Troubleshooting Steps You Can Try (with Caution):
Important: Disconnect the Power! Before attempting any troubleshooting, please turn off the air conditioner and unplug it from the power outlet or turn off the circuit breaker.
- Check for Obstructions: Inspect the indoor unit for any visible obstructions blocking the fan blade. Remove any debris you find.
- Inspect Wiring Connections: (If you’re comfortable doing so, and only after disconnecting the power) Open the indoor unit carefully to access the fan motor and wiring. Look for loose, damaged, or corroded wires. If you find any loose connections, try to re-secure them. If uncomfortable working with electrical components, skip this step and call a technician.
- Restart the Air Conditioner: After checking for obstructions and wiring issues, plug it back in and turn it on. See if the error code clears.
When to Call a Professional:
- You’re uncomfortable working with electrical components: Air conditioners involve electrical wiring, and it’s best to leave the repairs to a qualified technician if you’re not experienced.
- The error code persists after trying the troubleshooting steps. This indicates a more serious problem that requires professional diagnosis and repair.
- You suspect a faulty fan motor or control board: Replacing these components requires specialized tools and expertise.
What a Technician Will Do:
A qualified HVAC technician will:
- Correctly diagnose the problem: They’ll use specialized tools and knowledge to pinpoint the exact cause of the error code.
- Test the fan motor: They’ll use a multimeter to check the motor’s windings and ensure it’s receiving the correct voltage.
- Check the capacitor (if applicable): They’ll test its capacitance to ensure it functions correctly.
- Inspect the control board: They’ll look for signs of damage or malfunction on the control board.
- Replace faulty components: If necessary, they’ll replace the defective fan motor, capacitor, or control board with a new one.
- Ensure proper operation: After the repairs, they’ll test the air conditioner to ensure it works correctly.
In summary, Error code 22 on a Whirlpool air conditioner points to an issue with the indoor fan motor or its related components. While you can try some basic troubleshooting steps, it’s often best to call a qualified HVAC technician for proper diagnosis and repair.
