Xinke air conditioner is a product developed and designed by a wholly-owned subsidiary of Jiangsu Fengrun Group. It has been established for 20 years. Whether it is a household air conditioner or a commercial air conditioner, its configuration and appearance design are unique. It has reached the most advanced level in the world. The annual consumption of Xinke air conditioners has also increased by more than 250,000 units, and is increasing day by day. After we purchased it, we used Xinke air conditioners more and more often. However, as the frequency increased, Xinke air conditioners would inevitably become unusable.
If the Xinke air conditioner breaks down at home and needs repair, most people will immediately contact after-sales service and then have a repairman come to repair it. In fact, this is also the correct method. It is not recommended that you check the fault yourself if you don’t understand it, unless you have professional knowledge. However, it is better for everyone to know some common sense about electrical appliances, because daily maintenance is also very important.
Causes of Xinke air conditioner failure:
1. Insufficient refrigerant. You can easily perform a self-test to identify whether there is a fluorine leak.
2. Four-way valve cross-gas. The heat pump type Xinke air conditioner switches between cooling and heating states through a four-way valve. Some of the refrigerant that should participate in heat exchange returns directly from the compressor outlet pipe to the return pipe at the four-way valve, resulting in less refrigerant participating in heat exchange and a decrease in heat exchange efficiency, resulting in insufficient heating capacity.
3. The one-way valve (also called check valve) is leaking. The pressure difference between the high and low pressures of the refrigeration system decreases, the temperature of the outdoor heat exchanger increases, and the heat obtained from the outside decreases, resulting in insufficient heating capacity. By detecting the pressure when the system is running, it will be found that the pressure on the low-pressure side increases and the pressure difference between the high and low pressures decreases.
4. The defrost controller fails. If the Xinke air conditioner cannot enter defrost operation in time, frost will appear on the evaporator during heat pump heating, affecting the heat exchange efficiency of the Xinke air conditioner, resulting in insufficient heating capacity or even shutdown. We should focus on observing whether the defrost temperature sensing device is misplaced, the contacts are sticky or have poor contact, the fan impeller is slipping or the air duct is blocked, and the solenoid valve or starting relay is ineffective.
5. The auxiliary electric heating function fails. If the electric auxiliary heating control circuit or the electric auxiliary heating equipment fails and cannot work properly, the Xinke air conditioner will not be able to heat enough when the ambient temperature is relatively low, or even the Xinke air conditioner will not heat at all when the environment is harsh.
6. For heat pump-assisted electric heating type Xinke air conditioners, if the ambient temperature is high (above 5℃), the heating is normal, but the ambient temperature is low (below 0℃), the heating capacity is insufficient or does not control. If it is hot, you should suspect that the electric auxiliary heating control circuit or the electric auxiliary heating equipment is faulty. During maintenance, you should focus on checking these two parts.
7. Environmental factors.
Caused by all or part of the refrigerant leaking,
Troubleshooting: Find the leaking location, repair the leak, re-evacuate the refrigeration system, add refrigerant, etc. It should be repaired by professionals.
Cause 2. The filter is clogged.
Troubleshooting: The filter can be replaced, the refrigeration system should be re-evacuated, refrigerant added, etc., and should be repaired by professionals.
The compressor cannot operate.
Cause 1: Power failure.
Troubleshooting: Use a multimeter and electric pen to check and troubleshoot. If the fuse is broken, replace the fuse; if the wire is broken, replace the wire.
Cause 2: The power supply voltage is too low.
Do not use a multimeter to measure the voltage, and use a power supply voltage stabilizing device if necessary.
Cause 3: The wire connection is loose or broken.
Troubleshooting: Check the wire connection parts. Loose connectors should be re-inserted and tightened, and should be repaired by professionals.
The fan cannot operate.
Cause 1: The main control switch has poor contact.
Troubleshooting: Use a multimeter to measure the contact resistance of the main control switch. If the resistance is too large or zero, it should be repaired or replaced.
Cause 2: The fan motor coil is damaged.
Troubleshooting: Use a multimeter to check and replace the fan motor with the same specifications and the same speed.
Cause 3: The set screw between the fan motor and the blade is loose.
Troubleshooting: Tighten the set screws.
Cause 4: The fan capacitor is open or short-circuited.
Troubleshooting: Check the capacitor and replace it with the same specification.
The compressor starts and stops frequently.
Cause 1: The room temperature control value is improperly set.
Exclusion: Appropriately increase the difference between the indoor control temperature and the original room temperature.
Cause 2: The ambient temperature is too high.
Exclusion: Improve the working environment, such as setting up grilles to avoid direct sunlight, installing Xinke air conditioners in a well-ventilated environment, etc.
Cause 3: The condenser is too dirty.
Troubleshooting: Clean the condenser and remove dust on the outer surface of the condenser.

If Xinke air conditioner fails to heat, If it cannot be cooled or cannot be turned on, there must be its own solution. Before we send it to after-sales service for repair, why not try to do it yourself? You can also avoid the repair price. After repairing the Xinke air conditioner, we must restrain ourselves in use. Even if the weather in summer is too hot, we cannot let it work 24 hours a day. We must give our Xinke air conditioner a "holiday". To prevent it from being "overworked" and damaged again.
