What is the reason why Yuba is not hot?
1, the thermostat is always on or the thermostat is turned on too early, which makes the refrigeration system go through a large cycle too early and the outside temperature is very low. Especially when the car is running, the cold wind will soon cool the antifreeze, the engine water temperature will not come up, and the warm wind will not be hot.
2. The water pump impeller is damaged or lost, so that the flow through the warm air small water tank is not enough, and the heat can't come up.
3. There is air resistance in the engine cooling system, which leads to poor circulation of the cooling system, resulting in high water temperature and lukewarm air. If there is gas in the cooling system all the time, it is likely that the cylinder pad is damaged and the gas leaks into the cooling system; If the inlet pipe of the small heating tank is very hot and the outlet pipe is very cold, this situation should be that the small heating tank is blocked and should be replaced.
How to repair Yuba without heating?
1, motor or fan failure
Yuba's lack of hot air is generally caused by motor or fan failure. You can ask brand service personnel to come to your home for repair. In self-inspection, you have to cut off the power supply and remove all the warm bulbs, which are usually threaded and can be removed directly by rotating them in the opposite direction. Then remove the decorative board, there is a buckle at the back, which can be removed as long as it is pushed to the side, and then turn on the power supply with other patch panels to turn on the fan function.
If the blade does not move, it may be a motor problem; If the power is turned on, it may be a fan blade problem. You can call the brand official after-sales to consult the warranty and expenses of related parts and take corresponding maintenance measures.
2. The heating element is disconnected.
Focus on checking the zero line of the heating element of Yuba. Because of the high power, manufacturers are used to cutting corners and connecting the zero lines of all components with a single terminal, which leads to serious heating of the zero line and finally oxidation.
3. The switch is broken
Check the switch. If the switch is broken, replace it with a new one.
The above is the introduction of the maintenance method of Yuba without heating. Generally speaking, there are many reasons why Yuba fails to heat. When we find that Yuba can't give off heat, we first need to find out what causes it, and then we can take the right way to maintain it. If we can't solve the problem that Yuba can't heat itself, then we can ask professionals to come to our home for maintenance, but it will cost us a maintenance fee!
