What does Gree Air Conditioner Rb mean?

For Gree air conditioner, it is impossible to know what the air conditioner fault is just by saying that the fault ** is rb. Because of the failure of Gree air conditioner**, the arrangement of different models of air conditioner is different and there is no rule. Therefore, if you know that the fault ** is RB, you should take the air conditioner model to search for the Gree air conditioner fault ** summary table to see which part of the fault is.

However, for specific and accurate judgment, it is necessary for professionals to inspect and measure on the spot, and sometimes it is necessary to replace components.

In order to fool users, Gree deliberately made up a lot of models of air conditioners, and made this meaningless name, what model of Gree air conditioner must be very poor, Gree's technology and management are too inferior, only rely on hype, the product is not good. The failure rate is high.

Through my personal experience, the quality of Gree electrical appliances is poor, and the service is even worse. Anyway, I won't buy Gree products in the future.

I have used two Gree products, a floor fan, and the cover is actually fixed with a one-millimeter screw nut, which is very inconvenient to disassemble and easy to lose. All other products have a very convenient way to fix the formula, and it doesn't need to be "unique".

A Gree air conditioner, the outdoor unit actually has a tail --- a sensor connected to an ordinary soft wire outside the machine. This kind of product design shows that the technical level of Gree's technicians and the entire team is so low. Mine was installed on the sixth floor, and it was bitten off by a rat in less than half a year and could not be turned on.

The angry thing is to report for repair, the maintenance staff received **, and told that it was the mouse that bit off the sensor line (the maintenance personnel can accurately guess that it is the mouse that bites off the line, which shows that the failure rate is too high to say), and I want to pay 200 yuan for maintenance. The next day, I complained to the local city Gree Branch (one of the largest cities in the country), and replied that it was a fault caused by my poor natural environment, and I did have to charge for it. I really don't know what to do if the "environment" is on the first and second floors and I buy a Gree air conditioner.

Later, I also reported the incident to the head office of Gree through Gree's official **, hoping to get the opinion of the head office. However, there was no feedback from the after-sales service of the head office.

However, I have used a certain brand of air conditioner, five years later, the fan of the external unit was broken, a dozen **, immediately to repair, free replacement of the fan, no more words.

The reason why the air conditioner does not heat up: there is a problem with the capillary or check valve of the air conditioner.

Capillary: The capillary network simulates the mechanism of leaf veins and human capillaries, and consists of a capillary with an outer diameter of about the wall thickness and a main water supply and return pipe with an outer diameter of 20mm (wall thickness of 2mm or more).

Check valve: also known as check valve or check valve. It is used in hydraulic systems to prevent the reverse flow of oil or in pneumatic systems to prevent the reverse flow of compressed air.

What to do if the air conditioner does not heat due to this reason: Replace the capillary pipe or check valve to solve the problem of the air conditioner not heating.

Summary. Gree air conditioner PL fault** means that the DC input voltage inside the machine is too low, and the air conditioner cannot work normally at this voltage. This fault may be caused by loose sensor pins or poor contact; Or the sensor is damaged and the resistance value is wrong; or the control circuit board is faulty, unable to receive and send control signals; Or whether the AC/DC converter is faulty.

Gree air conditioner PL fault** means that the DC input voltage inside the machine is too low, and the air conditioner cannot work normally at this voltage. The reason for this fault may be that the sensor pin is loose or the backup key is poorly touched; Or the sensor is damaged and the resistance value is wrong; or the control circuit board is faulty, unable to receive and send control signals; Or whether the AC/DC converter is faulty.

Excuse me, but please go into more detail?

1. When the Gree air conditioner shows PL fault, it is mainly due to the low DC input voltage inside the machine, 2. This fault prompt may be a temporary problem with the current voltage, turn off the air conditioner and turn it on again, if the air conditioner no longer prompts the **, you can continue to use. 3. This fault prompt may be caused by loose pins or poor contact of the Chai Ling Ku sensor, at this time you can check the loose place of the sensor to see if you can solve the adjustment. 4. This fault prompt may also be due to the fact that the sensor itself has been damaged and needs to be replaced, as well as the failure of the control circuit board.

Summary. The piping system is clogged. Refer to the pressure gauge to judge, eliminate, and re-process systematically.

Dust and fouling in the evaporator or strainer. If the pressure and temperature of the system are not constant, clean the evaporator or filter. The battery cover of the remote control should be opened, and the small hole of the switch lock will be marked on the top, just press it with a toothpick, and every time you press the remote control, there will be a lock mark on the display, so it's good.

Hello, I'm glad to answer for you Gree air conditioner shows that RL is the phenomenon of the compressor protection device jumping out. Compressor overload protection will trip, indicating that the system is too high-pressure, the pressure is too high, or the overheating current is too high. Causes and elimination of high pressure and overheating:

Too much refrigerant. Reduce the refrigeration dose appropriately. Poor heat dissipation.

Check whether the condenser pipe has dirt and dirt, and clean the condenser.
