haier | air-conditioner Error Codes: Troubleshooting, Fixes & Prevention Tips explained below.
What Does CH25 Mean?❓
CH25 appears when the voltage falls below the minimum operating threshold required by the AC unit. This may occur during high-demand periods or when the home’s electrical wiring cannot maintain a stable supply.
air-conditioner - Causes of CH25 Error
- Low voltage from power provider
- Faulty or old home wiring
- Overloaded power circuits
- Loose power cable or terminal connection
- Using a long extension cord
air-conditioner - How to Fix CH25 Error❓
Restart the AC
- Turn off the unit and unplug it for 5 minutes.
- Plug back in and restart to see if the issue resolves.
Check Input Voltage
- Use a multimeter to test your wall socket.
- Contact an electrician if it’s below the recommended level.
Avoid Extension Cords
- Always plug directly into the wall socket.
Inspect Home Wiring
- Hire a licensed electrician to inspect for faults or overloading.
Use Voltage Stabilizer
- Install a stabilizer if your area experiences frequent drops.
air-conditioner - Helpful Tips
- Install a surge protector and stabilizer.
- Avoid running AC during known low-voltage hours.
- Don’t use multiple high-load appliances on the same circuit.
- Schedule an annual inspection of your electrical system.
- Make sure your AC has its own power line.
Frequently Asked Questions❓
- Question: Can I use an extension cord with my AC?
- Answer: It is not recommended. Long cords can drop voltage further and trigger CH25.
- Question: Is CH25 dangerous?
- Answer: It protects your AC, but repeated voltage drops can wear down components.
- Question: Do I need a stabilizer?
- Answer: Yes, if your area has frequent voltage drops or spikes.
