The possible reason is that the wire of the sensor is loose. Open the panel under the indoor unit, open the cover plate of the black electrical box, and plug in the wires again.

Refrigeration failure phenomenon of air conditioning pipe temperature sensor;

1. The resistance of the indoor ambient temperature sensor becomes larger, which leads to frequent startup failure of the air conditioner.

2. The resistance of indoor pipeline temperature sensor becomes smaller, which leads to the failure of the whole machine protection soon after startup.

3. The temperature sensitivity of indoor ambient temperature and pipeline temperature changes, leading to empty pit failure.

4. The change value of indoor pipe temperature is 0 Ω, which leads to the failure of remote starting of the whole machine.

Galanz air conditioning fault code:

E 1: The compressor current is too large, the compressor is overheated, the exhaust temperature is high, and the module is protected. Check whether the overload protector is disconnected and the compressor temperature sensor is short-circuited.

E2: indoor evaporator antifreeze protection.

E3: Short circuit or open circuit of indoor temperature sensor.

E4: Short circuit or open circuit of indoor evaporator tube temperature sensor.

E5: Indoor and outdoor communication failure. ?

F6 or FF 06 indicates PG motor failure.

F7 or FF 07 indicates that the room temperature sensor is faulty.

F8 or FF 08 indicates that the indoor pipeline temperature sensor is faulty.

F9 or FF 09 indicates that the outdoor pipeline temperature sensor is faulty.

Extended data:

Galanz air conditioner is positioned as "the largest specialized air conditioner manufacturing center in the world" and quickly enters the market from a high starting point. In September 2000, Galanz entered the air conditioning and refrigeration industry with 2 billion yuan. In the first freezing year (200 1), 500,000 units were produced and sold.

In 2002, it is estimated that the production and sales will be10.8 million vehicles, of which 600,000 vehicles will be sold domestically and10.2 million vehicles will be exported. In July 2007, Galanz Central Air Conditioning Co., Ltd. was established, and its annual sales in 20 10 exceeded 100 million, and the growth rate was obvious to all.

Galanz air conditioning series: V8, K8, Calm Bao, New Jubao, Q Ya, Smart Bao, Zunruifeng, Mengjingfeng, Zunmengfeng, Xiaokangbao, Chunfengbao, Ipoh, Zhipai and Yi Xuan.

As one of the outstanding representatives of China manufacturing and private enterprises in China, Galanz's 30-year history of steady growth and development is the corporate label of China's successful reform and opening up: before 10, Galanz started its business on a barren beach and built a textile industrial zone of 100 million yuan;

10In the second year, Galanz switched from the textile industry to the microwave oven industry, becoming one of the earliest township enterprises in China that successfully transformed and established a modern enterprise system, and quickly won the world champion of microwave ovens. 10 In the third year, Galanz began to build a multinational white goods group with microwave ovens, air conditioners, refrigerators, washing machines and household appliances as its core.
