What should I do if the elevator air conditioner is not refrigerated and the indicator light is yell

Check the remote control and cancel the timer function first; Then press the "mode" button repeatedly until there is a "snowflake" mode, make sure it is the refrigeration mode, and then turn it on, if it is not cooling, please contact the repair station. If you can refrigerate, there will be no problem.

Reasons why the yellow light of the air conditioner flashes and does not refrigerate:

1. First of all, it depends on whether it has just been turned on or has been running for a period of time, if it has just been turned on, it takes three minutes for the outdoor compressor to start;

2. If you have waited for about three minutes, the air conditioner still does not cool and heat, that is, the indoor and outdoor communication is not smooth or there is no refrigerant;

3. If it has been running for a period of time, it may be that the indoor temperature has reached the set temperature, and the outdoor unit will automatically stop first, and then turn on the machine when the indoor temperature is needed again.

Possible Causes:

1.The indoor or outdoor unit of the air conditioner is faulty and needs to be repaired or replaced.

2.Fluorine leakage occurs inside the air conditioning system, resulting in poor refrigeration and the need to add refrigerant. Trembling scum.

3.The air conditioner filter is clogged and needs to be cleaned or replaced.

4.If the power supply line of the air conditioner is faulty, you need to check whether the power supply line is normal.

5.The control panel of the air conditioner is faulty, and the control panel needs to be replaced.

It is recommended to contact a professional aircon maintenance personnel for inspection and repair.

The air conditioner indicator keeps flashing and does not refrigerate the reasons and solutions:

If the operation indicator of the Lingwan air conditioner flashes and does not refrigerate, it means that there are some problems inside the air conditioner, under normal circumstances, the air conditioner can be turned off and restarted, if it is still not solved after the shutdown, you can call the customer service of the air conditioner for consultation, or you need to find a professional to overhaul it, try to avoid disassembling it yourself.

If the dust mite lamp of the air conditioner is on, it means that the filter screen of the air conditioner needs to be cleaned, before cleaning the air conditioner filter, first open the indoor cover of the air conditioner, take out the filter, brush it with a clean vertical filter brush, brush most of the dirt attached to the filter screen, and gently brush the filter screen with a bottle brush after soaking, so that each filter hole is clear and transparent, without traces of dirt blockage, and install it on the body after drying and checking that it is intact.

Air conditioning power-saving tips: If the air conditioner is idle for too long, dust will accumulate, if it is not cleaned for a long time, it will cause poor heat dissipation of the external unit, and the evaporation of the internal evaporator is not smooth.

At the end of summer, if you don't continue to use the air conditioner, it's a good idea to clean the air conditioner once, then unplug it and cover it with a dust jacket. Before using the air conditioner, it is best to open the windows or wind for 10 minutes, and then close the doors and windows. Do not move the air conditioner while it is running, and do not put your hand in the air outlet.

1.Too much refrigerant. Reduce the refrigeration dose appropriately.

2.Poor heat dissipation. Check whether the cooling fan is rotating, whether the condenser pipe is dirty, and clean the condenser.

3.The piping system is clogged. Refer to the pressure gauge to judge, drain and flush and guess, and re-process the system.

4.Dust and fouling in the evaporator or strainer. The air flow becomes smaller, the system pressure and temperature are unstable, and the discrete type washes the evaporator or filter.

It could be due to the following reasons:

1.The air conditioner filter needs to be cleaned or replaced. If the aircon filter is clogged, the air flow will be restricted, causing the aircon to not work properly.

2.The air conditioner condenser or evaporator needs to be cleaned. If these parts are covered in dirt, they will not be able to absorb or release heat effectively, resulting in the air conditioner being unable to refrigerate.

3.The aircon compressor is faulty. If the air conditioner compressor is not working properly, it will not be able to compress the refrigerant into a high-pressure gas and thus will not be able to refrigerate.

4.Air conditioning refrigerant is insufficient. If the air conditioner does not have enough refrigerant, the air conditioner will not be able to control the vibrillation hall cold.

It could be due to the following reasons:

1.The inside of the air conditioner is faulty and needs to be repaired or replaced.

2.The air conditioner filter needs to be cleaned or replaced, resulting in insufficient air flow and affecting the cooling effect.

3.If the power supply line of the outdoor unit or indoor unit of the air vibrator is faulty, the power circuit needs to be checked for the collapsed beam.

4.The sensor of the outdoor unit of the air conditioner or the indoor group unit is faulty and needs to be replaced.

5.The air conditioner has insufficient refrigerant or leaks, and the refrigerant needs to be added or the leak point needs to be repaired.
