It is important to master these skills when repairing heaters!

Equipment that is used frequently, such as heaters, can also malfunction due to excessive use intensity or bad operating habits. For example, Hong Kong Junhong Electrical Appliance Repair Center encountered a situation where a Midea heater did not heat. The customer mentioned that this heater was used frequently every day, so the maintenance staff judged that the overheating protection caused the power outage. Later, they disassembled the base and found that the circuit of the heater was burnt. After replacing it, it immediately returned to normal. Considering that the heater was It is a commonly used electrical appliance in the home. Next, we will share some common maintenance skills.

1. How to troubleshoot if the heater fails to start due to power outage

No matter which brand of heater it is, it has overheat protection. If we encounter the heater overheat protection in daily use, we need to cut off the power and leave it for a period of time before using it again. If the heater cannot be restarted or cannot heat, Then directly follow the following process to investigate and operate.

(1) Turn off the power and check whether the wires are burned. If there is no problem with the power cord, disassemble the base and check the internal circuits and motherboard. If there are black burn marks, it means it is burnt and the corresponding components need to be replaced.

(2) If there is no problem with the power cord and base, check whether there is water or dust on the base and edges of the heater, clean it, and then look for burnt spots.

(3) If there are no problems with the above, it means that the heating element is faulty, and the heating element must be replaced.

2. The temperature of the heating machine is abnormal or cannot be kept warm.

Another situation when using a heating machine is that the temperature is abnormal or cannot be kept warm. Users find that some heating machines will heat slowly or heat quickly and slowly after long-term high-intensity use. In this regard, the heating machine can be repaired according to the following process. :.

(1) If the heater is not well insulated, it depends on whether there is scale and carbon deposits. Clean the interior after the power is turned off. If water stains are found around the heater, it should be cleaned in time and ensure that it is placed in a safe and reasonable location.

(2) Usually the temperature fluctuation of the heater is related to the motherboard. For this, a motherboard of the same model must be used for replacement testing. If the temperature control is normal after the motherboard of the same model is replaced, it means the motherboard is faulty.

(3) If the thermal insulation performance of the heater deteriorates, check whether the thermal insulation cotton and other materials of the heater itself are damaged. In this way, as long as the thermal insulation function is normal, the water temperature insulation can be ensured.

What I just shared is my experience and experience in repairing heaters. Because heaters are used frequently and their structures become more complex with the increase of functional models, so you should pay attention to the intensity of use in daily use, especially when encountering overheating protection. Dissipate heat first and wait for it to cool before use.
