What is the reason why the indicator light of the heater is on, the fan does not rotate, and it does

For your problem, first of all, check whether the switch of the heating air is normal, that is, the base switch, the fan does not turn to explain, whether there is a mechanical block, or a certain element of the circuit is broken, such as thermostat, broken wire, etc., in short, to check carefully, but also to see the resistance of some heating elements, whether it is damaged, it is best to measure it with a multimeter, so that it can be more accurate, otherwise it can not be solved, I really don't understand, you can ask some professionals, but also to see whether some peripheral switches are damaged, Hope it helps, it's just a personal opinion.

Indicate that the power supply has been connected, check whether the power supply of the fan and the power supply of heating are normal, and check the switch and connected lines.

The general heater circuit is as follows:

Hello: 1, the indicator light is on, indicating [It's powered on and there's power

2. If the fan does not rotate or heat, it may be [Temperature controllerPoor contact with damage.

3. Electric heating appliances are availableOverheat protectionThe action of the overheat protector is also one of the reasons.

4. The specific situation should be determined by [Qualified professional electricianCheck to be sure.

The hot melt pen should be broken. The fan of the warped heater is turned on and the indicator light is on, but the non-heating should be the reason why the hot melt pen is broken, and it is best to find an after-sales master to repair it professionally, which may be better.

If it can't run normally or run chaotically, it still can't run normally after shutdown and restart, generally the main control board is broken and can't run normally according to the program. It is recommended to contact the after-sales service, or ask the professional maintenance personnel of this brand to check and repair. FYI.

The indicator light of the heater indicates that the power supply is good, the fan does not turn and does not heat, it may be that the switch is broken or the heating thermostat is broken, remove it and check it carefully.

This situation shows that the power supply is normal, the key to check the fan switch Its structure is to send power to the fan switch first, and at the same time send it to the heating switch through the fan switch, as long as the fan does not supply power and heating is high, there will be no electricity, so you need to check the fan switch circuit first Simple schematic as shown in the figure.

There is a problem with the internal power supply line.

It is also possible that the fan does not rotate due to a problem with the motor.

The thermostat is broken, just replace it.

Since the fan of the heater does not rotate, there is no heat. Therefore, when repairing the heater, it is sometimes not possible to replace the temperature controller when it burns out.

The heater working indicator light is not lit and the heater does not work, it should be that the heater is faulty, the plug-in turn on switch indicator light is not lit, the power supply is not on, check whether the socket is normal, the socket is normal, check whether the heater fuse is blown, if there is a fuse, it may be that the heater is damaged and needs to be repaired.

The heater has a large heat dissipation area, and there are two heating methods to choose from; Long service life and good safety performance; The heat conversion rate is high, and the energy saving effect is good. Its advantages are as follows:

1. Heat concentration, large heat dissipation area, high thermal efficiency. Precise parabolic energy gathering technology, thermal efficiency increased by 50%. The heating outside the red distance heats up quickly, and the heating is 3 meters away from the ultra-long distance.

Two different heating methods can be freely selected to meet different thermal needs. The power of the two gears is adjustable, and the heat can be selected according to your heart.

2. High-quality heating components are used to ensure service life. The heating element has excellent broadband characteristics and has the effect of health care physiotherapy. The whole adopts a double protection design to ensure safety.

3. Good energy-saving effect. The heater uses infrared heating technology to provide heat, so the heat conversion rate is very high, which can not only improve the heating speed, but also play an energy-saving role and save more electricity expenses for the family, which is an energy-saving product. With the forced convection warm air, the room temperature can be quickly raised.

In addition, the heater generally has the advantages of small size and light weight, especially suitable for heating in small rooms. A fan heater with a unique splash-proof structure that can be used in the bathroom. Disadvantages of heaters:

The working indicator light of the heater means that the heater is working, if the indicator light is not on, it may be that the heater is damaged. Repairs are needed.

If the heater is working, only cold air will blow out after opening, but there is no hot air when the hot heating function is turned on, and the indicator light of the heating lamp will not be lit.

There may be the following reasons for rolling resistance:

1.Fan motor failure: The motor is damaged or the circuit is faulty, causing the fan to not rotate properly.

2.Fan rotor stuck: It may be because dust or other debris gets inside the fan, causing the rotor to get stuck.

3.Faulty fan capacitor: The capacitor is an important part of the fan circuit, and if the capacitor is damaged, the fan will not work properly.

4.Faulty fan switch: The fan switch may be damaged or in poor contact, causing the fan to not start properly.

5.Power Issues: If the power supply voltage is unstable or the power supply fails, it can also cause the fan to not work properly. Chang Liangyu.

It is recommended to check the above problems, if it cannot be solved, it is recommended to contact professional maintenance personnel for maintenance.

There are a few reasons why a home heater may fail, and you can test it out.

1. Press the function button of the household heater, if the light-emitting diode indicates the normal range, but the heater does not blow air.

This shows that although the power supply branch is normal, the reason may lie in the power supply branch of the relay, that is, there may be no place to close between the resistors of the heater, so that the heater does not run, so that the fan motor and the synchronous motor and the two temperature coefficient heaters have no way to power up.

Second, the mini heater does not run after the power is turned on, and the light of the power indicator LED is not on.

Check whether the temperature controller of the heater is burned out, then you need to replace a temperature controller and re-turn on the power supply, the power supply indicates that the light-emitting diode is bright, at this time turn on the heater, if you find that the fan is not rotating, then the motor has been damaged, and you only need to replace the new motor to use.

Since the fan of the heater does not rotate, there is no way for the heat to dissipate, and it accumulates in the body of the heater, and when it reaches the temperature set before, the resettable thermostat is damaged due to frequent action. Therefore, when repairing the heater, sometimes the temperature controller burns out and sometimes it can not be replaced, to find out what the specific cause of the short circuit is, the motor is damaged or the air inlet and outlet pipe is not passable, which can cause the temperature regulator to burn out.

3. After using the household heater for a period of time, I feel that the temperature increase is slowly decreasing, but it is very hot when it touches the air outlet on the surface of the heater.

If this happens, it may be that your use environment is too dirty, and too much dust has accumulated at the air inlet, so that the wind cannot come out smoothly. Because the temperature regulator has the characteristics of constant temperature, the greater the air flow blowing into the temperature coefficient regulator, the more the cold air can rise, and vice versa, the degree of air flow and temperature rise is inversely proportional. We know that there is a filter at the air inlet, which can be taken down and cleaned to eliminate this fault.

The reason why you put your hand on the air outlet and feel hotter than before is because the heater raises the air temperature according to the gas convection, and increases the indoor temperature by enhancing the convection.

Fourth, the failure of the low heat gear occurs, and there is no great difference between the high heat gear and the low heat gear heating up.

When there is no hot air blowing in the low heat block of the home heater, and there is hot air in the high heat bracket, it is a problem with the low heat branch road. After the heater is energized, press the switch twice, listen to the relay if there is any strange sound, if there is a sound lead may be detached, so that the heater can not be energized and heated, open the case and reconnect it; If there is no sound, it is generally a problem with the relay circuit branch, then it is necessary to check whether the resistive elements in the heater have been damaged.

Possible reasons are:

1.Fan motor failure: The rental imitation wide fan motor may malfunction, resulting in the failure to rotate normally.

2.Stuck fan blades: Fan blades may become stuck with dust or other freckles, preventing them from rotating properly.

3.Faulty fan circuit: The fan circuit may be faulty, causing it to not function properly. Bad bright.

4.Fan power failure: The fan power supply may be faulty, causing it to fail to function properly.

5.Faulty fan controller: The fan controller may be faulty, causing it to not function properly.

The above aspects need to be examined to find out the specific cause and fix it.

Summary. Good morning, the heater does not start and the power indicator does not light up is a common problem, the reasons for the analysis of the heater are as follows: article **1 fuel heater.

1. Overheating protector protects the industrial fuel heater with an overheating protection device, which will automatically shut down once it is overheated. If you have this problem, you can turn off the power and wait 10 minutes before turning it back on. 2. Check whether there is electricity when the power supply is not powered, and whether the power cord and extension cord are connected correctly.

Resolve the issue accordingly based on the details. Third, the fuse is broken and the damaged fuse can be replaced directly, pay attention to the selection of the best quality fuse.

What's the matter that the heater working indicator light doesn't light up and the automatic mode can't start?
