This Gree Air can be repaired once on January 10. It seems that the F2 code was issued that time. The master came here and said that it was repaired. He charged 60 yuan and left. At that time, I also sighed that the maintenance was cheap, but it seemed that it would take two months before it could go again. The current fault phenomenon is that the external unit will stop after starting heating for about two minutes, and the control panel will display F4 for a few seconds, then the display temperature will resume. After a while, the external machine will start again to start heating, and then stop to display F4, and so on repeatedly.
After checking on the Internet, F4 should be the fault of the exhaust sensor of the external machine. It costs less than 10 yuan to buy a sensor on Taobao. But I'm not sure whether it's OK to replace this sensor. Besides, the external machine is hung on the outer wall of the sixth floor, so it's not easy to dismantle it. If I could take a ladder and dismantle it, I would do it myself.
At 12:12 at noon, Gree 400 reported for repair. At 12:25, he received a local after-sales call to arrange a master. At 13:4, he received a call from the master because he was still on his way home and asked the master to wait. At 13:24, the master was notified to come over. At 13:32, the master arrived. At 13:57, he scanned the code and paid 150 yuan to finish the maintenance. The reason why I wrote the time point so clearly is that I think this report is efficient. In January, my wife reported for repair. It seems that it took two or three days for a master to come
The master came to replace an exhaust sensor of the external machine, which took more than 20 minutes and was delivered. I don't think the fees are too expensive. After all, before I reported for repair, I thought that if I had to pay more than 100 yuan for repair, it would be in line with my psychological expectations. But I was still a little unwilling. After all, if I did it myself, it would cost me ten yuan. Finally, I can only comfort myself, without risking going downstairs, and I don't know the specific location of the sensor before the master dismantles it. In fact, the master didn't know the specific location when he disassembled it, because he couldn't see it. He only knew to disassemble the shell in front of the external machine before replacing it.
A hundred and fifty is a hundred and fifty. It's worth it if I can stay safe for a few years. Master scanned the code and saw that my air energy was purchased in October 2014. How time flies!
By the way, I asked the master about changing the magnesium stick. The master said that he had not changed the magnesium stick for so many years in his career. He said that the water quality of Chenxi was OK, and it was generally unnecessary to change it. I asked how I knew to replace the magnesium rod. The master said that there would be a code, but the fault code I found on the Internet did not contain anything about the magnesium rod, nor did I know whether it was a trick. Forget it. One day when you are bored, try another one yourself.
