Hello friends, today we will repair a heater This is Oaks Let's see the label on the back Oakes then this power is 2 kilowatts Not big in size but still quite powerful Now its problem is that it can blow air outside But the wind that blows out is natural wind not hot air Now let's take it apart and examine it After taking it apart, I found that the inside was very dirty I lightened it with a hair dryer Then there is still dirt on the fan let's just leave it alone Let's take a look at its internal structure is very simple This is a temperature switch Then this is a gear switch Then it's a heating wire this is the fan It's like being in our house It's the same hair dryer you use to dry your hair. But it has more power Its working principle is very simple. when we heat this up And when all the fans are on The heating wire in front is hot after fever Then the fan blows the hot air blow him out so as to achieve a warming effect And now his problem is that the fan does not heat up So the wind he came out to ask is the natural wind like this situation We're going to check this heating wire first see if he has any problems Mainly check this piece And the switch that controls him Let's heat this up first Si take it out for him to check Check to see if there is any burnt on the heating wire It looks quite new No burnt out was found Then we take a closer look There is still a temperature insurance on it Let's first measure it with a meter See if there is an open circuit in the thermal fuse if he breaks this The heating wire will definitely not be energized Then it won't get hot let's check it Let's use the Fengming file of the watch to test it this burnt out It is normal that it is directly turned on and there is no resistance value. That's how it should be normally it should be like this Its problem is that the thermal fuse is burned out let's take it apart and see Let's take a look at this model, it's 121 degrees We cut it off on both sides with scissors then replace it with a new one Then with a soldering iron we solder it firmly Because the power is relatively large Be sure to solder it firmly It is now welded When replacing this temperature insurance Everyone must pay attention It's a soldering iron Try not to weld him for a long time If you weld this plus welding for a long time If the temperature exceeds his temperature It will blow the insurance Then we put the shell in and try it out should be fixed After power on, let's open it up and have a look Adjust to the highest gear and then adjust the temperature to the maximum temperature This hot wind is still quite enough it's perfectly fine It's hotter now It's actually easier to repair Well the video thank you for watching and we will see you next time
