Sanyo Electric Co., Ltd. is a Japanese electronics company that was a former member of the Fortune 500 Global. With headquarters in Moriguchi, Osaka prefecture, Japan the company had more than 230 subsidiaries and affiliates. Founded by Toshio lue back in 1947 the company has made a great mark on the world. However, things took a turn when in 2009 Panasonic purchased 50.2% stocks of Sanyo making it a subsidiary of Panasonic. In just two years Panasonic purchased 100% stocks making it the sole owner.
Sanyo started its journey with Japan’s first plastic radio and pulsator-type washing machine launched in 1954. It was not until 1970 that Sanyo introduced audio equipment, car stereos, and other consumer electronics.
Sanyo might be a high-ranking company, but from time to time customers have complained about system errors. Fortunately, most of these errors can be fixed on your own. So rather than ignoring the error codes, your appliance is showing its time to note down the Sanyo air conditioner error code and get to the bottom of the problem. To help you out we have listed down the most common error codes of Sanyo air conditioners.
Since the indications cover various units, the corresponding parts listed below may not be present in some models.

Troubleshooting
If your air conditioner does not work properly, first check the following points before requesting service. If it still does not work properly, contact your dealer or service center.
| Trouble | Possible Cause |
|---|---|
| Air conditioner does not run at all. | 1. Power failure. Restore power. 2. Leakage circuit breaker tripped. Contact service center. 3. Line voltage is too low. Consult your electrician or dealer. 4. Batteries in remote control unit have run down. Replace batteries. |
| Operation lamp blinks and air conditioner does not operate. | Trouble in system. Contact service center. |
| Compressor runs but soon stops. | Obstruction in front of condenser coil. Remove obstruction. |
| Poor cooling (or heating) performance. | 1. Dirty or clogged air filter. Clean air filter to improve airflow. 2. Heat source or many people in room. Eliminate heat source if possible. |
| Clicking sound is heard from the air conditioner. | In heating or cooling operation, any plastic parts may expand or shrink due to a sudden temperature change. In this event, a clicking sound may occur. This is normal, and the sound will soon disappear. |
| Operation lamp lights but outdoor unit will not run. | The use of cellular phones near the air conditioner may cause disturbance to its normal operation. 1. Turn off the power then restart the air conditioner after a while. 2. Consult your dealer. |
