Question:

But after 3 minutes on the machine, there is no electricity, what's the matter?

But after 3 minutes on the machine, there is no electricity, what's the matter?

Answer:

At first glance, under cooling state, adjust the temperature controller to the user, set the temperature 6 degrees lower than room temperature time temperature to 8 DEG C in 15 minutes after running, the normal air conditioning in the indoor machine hydraulic pipe should be no frosting phenomenon, if this phenomenon if there is leakage of fluorine failure. If there is a hydraulic pipe connector of indoor machine oil, which also shows that air conditioning has produced fluorine leakage phenomenon.Followed by touch, touch the air conditioning after the condenser shutter fan, if the hand temperature is not changed, and the compressor at work, which means that the fluorine has been run. Because the compressor is working, there is no heating or cooling.If you find that the compressor has been working since it started, there is no vibration of the compressor, and the sound of the compressor self shock is larger than that of the newly purchased air conditioner. This may be the abnormal sound caused by leakage of fluorine.Finally, temperature measurement. Find a thermometer, close to the air outlet, look at the thermometer indicates whether 6 to 8 DEG C lower than room temperature, as shown in the temperature lower than the indoor temperature less than 5 degrees even at room temperature and not much difference between, continues and the compressor work, it shows that air conditioning fluoride may have leaked.
If you can't open the circuit check all the best hit the table of capacitance, resistance to clamp type table file, two probe and two terminal capacitor contact, began to pass, slowly not normal. The frequent capacitance of the switch is easily damaged by current. If there is no problem, it may be where the leakage of fluoride, or Freon is not enough. If the system does not leak, the difference is only fluoride, that is, fluoride will be OK, if the leak, then a little trouble
First of all, I suggest you make sure the compressor has no work and listen to the sound. No words starting with his hand to open the machine shell surface of compressor, see is not hot, hot water is available as the compressor cooling after the boot, if opened, let him run for a period of time, or if that is automatically shut down the compressor overheating protection. There are many conditions that cause overheating protection. The main points are normal and abnormal. Normal is when the air conditioning works in very harsh conditions, such as very high ambient temperature, refrigeration, and press load is too large to protect. Non normal, mainly the system problems, such as Freon shortage, the pipeline blocked, the fan does not turn, and so on, according to the specific circumstances of the decision.
