Toshiba Air Conditioner Error Codes

Toshiba air conditioners have become a trusted choice in Singapore due to their high efficiency, durability, and advanced inverter technology, which suits Singapore’s humid and warm environment. These are the top units of Toshiba air conditioners that many Singaporeans love:

• Toshiba RAS-24S3KS-V is the top-buy air conditioner among homeowners due to its superior energy efficiency and powerful DC Hybrid Inverter system.
• Toshiba RAS-N4KCVP is also one of the top-buy air conditioner inverters among Singaporeans due to its ultra-quiet operation and robust cooling performance.
• Toshiba RAS-13SKV-E3 is a top seller for small apartments and offices across Singapore. 

Although Toshiba is known for its quality, that doesn’t mean that you won’t experience a few issues down the road. All air conditioners, even those made by reputable companies like Toshiba, will naturally run into a few problems.

But the good news is, your unit can display an error code to tell you what’s going on. Here’s a list of Toshiba aircon error codes, as well as their corresponding meanings.
