The consequences of long-term use of range hoods and the direction of repair!

The range hood is one of the necessary equipment in restaurants now. The range hood may not cause major problems in the short term, but after long-term use, failure is inevitable. Today, Hong Kong Junhong Electrical Appliance Repair Company received a case of repairing Whirlpool range hoods. Troubleshoot minor faults one by one.

1. The indicator light does not light up

The indicator light is often caused by a sensor problem. If the sensor surface is stained, it may cause the sensor to malfunction. Therefore, the master who repairs Whirlpool range hoods will directly remove the sensor, and then wipe and clean the internal grille and the dirt on the sensor surface with anhydrous alcohol. Generally, the fault can be eliminated in a long time. If it still cannot be restored, That means the sensor is aging and needs to be replaced.

Second, the sound is loud and the casing is hot.

The loud sound may be caused by worn shafts and loose parts. Generally speaking, Hong Kong Junhong electrical repair masters will remove the fan blades and check whether the rotating shaft is shaking. If it is loose, it means that the rotating shaft is just short of oil. But if it is loose, it means that it is seriously worn and needs to be replaced directly. The reason why the casing is hot is because the power is reached, but the work is in vain.

Third, the effect of smoking oil smoke is poor

1. There are many different reasons for poor results. Exhaust ducts are the number one reason. Therefore, you need to first check whether the exhaust pipe is too long or the pipe is damaged, and then check whether the direction of the outlet is blocked. Or it may be that the connection between the exhaust pipe and the device is leaking, causing insufficient suction.

2. If the voltage is relatively low, the power may be damaged. You can check the current with a multimeter. It may be caused by leakage during operation or a certain fault in the power strip. Just change the plug-in position.

Four, unable to start

There are only two possibilities for failure to start. The first is that the power supply fails. This has been said before. You only need to ask Hong Kong Junhong Electrical Repair to conduct a survey on the power supply to find out where the problem lies.

Another problem is caused by poor contact, or short circuit. Of course, there may also be a problem with the computer board. Therefore, the master needs to check starting from the circuit. If it is the computer board, the computer board can only be replaced.

Of course, the problems with Whirlpool range hoods are not limited to the above points. After all, the above are relatively common problems. Therefore, if you want to thoroughly inspect and repair your Whirlpool range hood, you must ask a professional maintenance team to handle it!
