The dryer is one of the commonly used appliances in our family, but sometimes it may break down.The following are some common dryer failures and their solutions:
1. The dryer cannot be started: first check whether the plug is plugged tightly, and then ensure that the power switch is turned on.If all these are OK, you can try to replace the power cord or check whether the fuse is damaged.
2. The dryer has no heating effect: first check whether the bulb inside the oven is on, if not, it may be caused by the bulb damage.In addition, check whether the fuse and temperature controller work normally.If all the above are OK, it may be that the heating element (such as the heater) is faulty and needs to be replaced.
3. The drying time is too long: first make sure to clean the filter screen and exhaust pipe, and ensure that the air circulation is smooth.In addition, check whether the exhaust pipe is blocked or bent too much, resulting in poor air circulation.
4. Porcelain lining broken: when you hear a sudden noise and find that the clothes stop rotating, it is likely that the transmission belt is loose or broken.The solution is to remove the old drive belt and replace it with a new one.
5. The dryer makes noise: if the dryer makes abnormal noise during operation, it may be caused by bearing wear or motor failure.It is necessary to disassemble the dryer housing and check whether the bearing or motor needs to be replaced.
No matter what problem you encounter, it is important to disconnect the power supply first to ensure your own safety.If none of the above methods can solve the problem, it is better to ask professional technicians for maintenance.
The electric fan has been used for a long time, and it is normal for it to fail.But what should we do when the electric fan fails?Xiao Bian has sorted out some common troubleshooting methods for electric fans for your reference.Common fault handling method of electric fan 1. Ensure that there is lubricating oil in the fan shaft, or the motor with fan blades on it will not be able to drag.If you are at home, you can choose to turn off the power, and then move the blades. If the rotation is stiff, there is basically no lubricating oil.2. Wear caused by long time use.If a fan is used for a long time, the motor will be lost, and the shaft sleeve of the motor will be easily burned off after being worn.3. The fan does not rotate due to overheating.There is a motor in the fan device. There will be an overheating circuit breaker in the motor. If there is a short circuit in the coil winding, the heat will increase in a short time. In this case, the motor will not move.4. The starting capacitance is reduced.When the fan is used for a long time, the capacitance capacity will be reduced, resulting in a smaller starting torque of the motor and unable to drive the load.5. Many times, the reason why the fan blades do not rotate is poor maintenance.If the fan blade rotates stiffly by hand after turning off the power supply, some lubricating oil should be used to drop into the rotating shaft so that it can be lubricated, so as not to affect the motor to drag the fan blade.6. The simplest way to prevent the blades from rotating due to wear is to replace the parts, especially the shaft sleeve, which is easy to burn off after wear.7. If the fan does not rotate due to the reduced capacitance, you can remove the capacitance and replace it with a new one of the same model. It is recommended to choose a capacitor 20% larger than the original one, which will have better rotating effect.8. If the axial clearance of the shaft is too large, you can choose to remove the motor and adjust the shim.However, remember that when installing the motor back, the rotor must be concentric with the bearing. The lubrication screw should be slowly tightened diagonally. Later, knock the shaft with a wooden handle to ensure that it is concentric.9. If it is due to electrical failure, check each line of the wiring, sometimes the wire is damaged, and repair the problem.The latest quotation of floor fan Floor fan is the most common type of fan. Most household fans buy floor fans.The price of Midea floor fans is generally between 100 and 150, and that of slightly better floor fans is around 200. Generally, the price is not very expensive.The electric fan, also called fan or fan for short, is a kind of household appliance that uses a motor to drive the fan blades to rotate to accelerate the air circulation. It is mainly used for cooling, relieving heat and circulating air.It is widely used in homes, offices, shops, hospitals, hotels and other places.The electric fan is mainly composed of fan head, fan blade, net cover, control device and other components.The fan head includes motor, front and rear end covers, shaking head air supply mechanism, etc.The main components of the electric fan are: AC motor.Its working principle is: the electrified coil rotates under the force in the magnetic field.Electric energy is converted into mechanical energy. At the same time, due to coil resistance, it is inevitable that some electric energy will be converted into heat energy.The common household electric fan is essentially an axial flow fan, that is, the flow direction of the wind is parallel to the rotation axis of the fan blade.After reading the common troubleshooting methods of electric fan introduced by Xiao Bian, you now know how to deal with the fault of electric fan.However, I think it would be better to ask professional personnel for maintenance if we really encounter a very difficult problem.
Provide drying system equipment, which can be used for fly ash, slag, river sand and other materials that need to remove water, as well as common dryer system failure handling? 1. Why is the air vent of fluidized bed boiler often burned, the pulverized coal burnout is low, and the coal consumption is high. 2. The dryer vibrates too much, the tire wears too fast, and the barrel wear is solved. 3. Bag pasting, burning, fast wear and other problems of bag type dust remover.
Troubleshooting temperature method for temperature sensor of Cygnet dryer: 1. The fault of the temperature probe cannot be eliminated by pressing reset. It is the hardware fault of the temperature sensor probe. Check whether the probe is damaged (broken, bent, etc.). It is generally installed in the heat source heat exchange vent pipe or drying box. 2. It may also be caused by the insecure signal wiring from the probe to the temperature controller. Check whether the probe hardware is damaged first, and then check the probe wiring
If the broken line bottle dryer fails, if you want to remove the surgery for elective repair, you can have a set screw at the top and the edge. After you can remove it with a screwdriver, it is easy to disassemble Brother Zhao for internal maintenance
1、 Turn on the power, the computer version does not light up? Answer: 1. Check whether the fuse is burned out (GW401D computer version has its own fuse on the back, which is used for 35 and 50 baking) 2. Check whether the temperature controller is unblocked by electric heating dryer 3. 12, 16, 20, 100 dryness check whether the transformer is in good condition 2、 When the machine starts, the drum does not rotate? Answer: 1. Check whether the contactor is closed 2. Check whether the fuse is burned out 3. Check whether the thermal protection works normally 4. Check whether the belt is loose 5.
