Hisense AC Error Codes List and Fixes

Hisense is a multinational white goods and electronics manufacturer based in China. It is the largest television manufacturer in China since 2004, yet offers a wide range of other electrons and appliances as well. Offering its products under a range of brands such as Sharp, Toshiba, Hisense, Ronshen, Kelon, and Gorenje. While the brand name may vary, the products are designed and manufactured by Hisense.

Apart from TVs, the second focus Hisense has is on air conditioning units. These units are available for home and office use, and can easily match your requirements. With a wide range of selections, you cannot go wrong with the one that compliments your space. However, like any other electronic appliance, Hisense ACs are open to errors and issues. Fortunately, most of them are minor and easily fixable.

To help you out we have listed down some of the most common error codes for Hisense ACs. Start by noting down the error code, and match it using the list below. Once you have the error code you can easily find out which area of your air conditioner is acting up, and how to best deal with the situation at hand. Rather than letting someone poke through the system, you can ensure a quick and easy fix.

Troubleshooting

Hisense Air Conditioner Troubleshooting

The following cases may not always be a malfunction, please check it before asking for service.

Trouble: Does not run

Analysis:

  • If the protector trip or fuse is blown.
  • If the plug is not properly plugged.
  • If batteries in the remote controller exhausted.
  • Please wait for 3 minutes and start again, protector device may be preventing unit to work

Trouble: No cooling or heating air

Analysis:

  • Is the air filter dirty?
  • Are the intakes and outlets of the air conditioner blocked?
  • Is the temperature set properly?

Trouble: Ineffective control

Analysis: If strong interference(from excessive static electricity discharge, power supply voltage abnormality presents, operation will be abnormal. At this time, disconnect from the power supply and connect back 2-3 seconds later.

Trouble: Peculiar odor

Analysis: This odor may come from another source such as furniture, cigarette etc, which is sucked in the unit and blows out with the air.
