According to some reports, about a third of the Russian air conditioning market is represented by the products of this company. Founded in the early 80s of the last century, products Haer quickly gained popularity due to the high quality of technology and the use of the latest technological developments. Now Haier is one of the hundred most famous equipment manufacturers in the world, one of the first among Chinese firms to officially enter the US market.
Common mistakes
Most often, the errors of the Haer air conditioners are caused by improper operation and illiterate attempts to repair the devices themselves.
Having studied the error codes for haier air conditioners, it will be much easier to figure out.
