Reasons and solutions for non-rotation of air conditioners:
Reason 1: the remote control pattern is incorrect. Check if the remote is set for refrigeration mode。
Solutions: use air-conditioning remote control to adjust the pattern to a state showing "refrigeration" or "snowflake" at temperatures of 26 or less。
Reason 2: power is out. Check the power circuit. Indoor and outdoor machines are connected by means of a contact point, through which the power is delivered, and when the contact point is damaged, it means that the outdoors and compressors cannot receive the power and that the outdoors cannot perform normal work。
Solutions: observe working sound (including outdoor fans and compressors). If the outdoor fans function, this means that the control circuit is largely normal. The compressor should be observed if it is activated and if it is not activated, the power should be checked for normality。
Reason 3: computer plate failure. The operation of outdoors is controlled with a computer panel, which may also fail when it is not。
Solutions: check whether the computer boards are working properly and if anomalies arise, examine the repairs by professional maintenance staff。
Reason 4: component damaged. When the air conditioner component is damaged, it also results in non-working of the air conditioner outdoors. Air-conditioning compressors are activated, the compressor is damaged so that the outside air-conditioning room is not rotated, and the outside air-conditioning room is disabled。
Solutions: an air-conditioning compressor will need to be repaired or replaced when the air-conditioning compressor's electrical capacity is damaged or the air-conditioning compressor's damage renders the air-conditioning outdoors inoperable. In the case of damage to the exterior air-conditioning unit, the replacement of the exterior fan is required, and the exterior air-conditioning unit is functioning normally。
Extension reading: air-conditioning fluorine correction methods
The methodology is as follows:
1 air-conditioning fluorinated fluorine may be caused by: fluorine leakage due to poor speakers; overlapping of speakers ' mouths; tilting of pre-expanded cutting tubes; unequally thick piped walls resulting in unequally thick horn-making walls; too small or too large horn-making; cutting of inner walls; hair punctures in the extended mouth; cracks in the speakers ' mouth; and bruises in the inside of the speakers ' mouth。
The solution is usually to make the horns, which are strictly in accordance with the requirements of the amplifier process, smooth on the surface and even on the surroundings, so as to avoid squeezing out the small horns, making the seals too small, and to keep the lines flat and to keep the uncorrupted bends and uncorrupted connections closed for extended horns。
The reasons for fluorine leakage in air conditioning are many, and it is important to find technicians to maintain it, and if it is determined that it is, it is necessary to identify the missing points. There are two simple methods of checking, one in a pressurized form and the other in a vacuum。
Both indoors and outdoors are to be separated and checked by tightening the three valves of the two sizes. If they can't find out, they'll have to be tested with water. In any case, it is important to identify the missing points before refrigerants can be added。
Some of the friends who bought the new air conditioner found that it was fluorine-free, which was a problem with the quality of the air conditioner, probably a leak caused by the damage to the parts, and probably a broken copper screw of the air conditioner. It's very unlikely that the copper screws at the plant will be able to slip. It's possible that the copper horns will be broken when the copper screws are screwed. This will require a new horn mouth, which will be fined with fluorine。
Air-conditioning fluorine detection methods
Thermometer measurements. An average thermometer may be used to detect the temperature of the vent and the vent, respectively, and to compare it with a temperature difference greater than 8°c, indicating that the air conditioner is functioning normally; leakage of fluorine is possible. After all, how much of the freon air conditioning directly affects the cooling, heating effect of air conditioning。
Ii. Observations. This method is more suitable for the summer by keeping air conditioners under cooling conditions, setting temperatures below approximately 8 degrees celsius in the room, and observing the presence of frosts in the outer air-conditioning room high pressure tube (minion tube). In the event of severe frost, which suggests that air conditioning is less fluorinated, users are advised not to operate air conditioning. Otherwise, it would lead to thermal protection of air-conditioning compressors。
Iii. Soap-based testing. With a wet rag, the soap is poured and air conditioner connections are tested for bubbles。
