Can the mainboard of Robello wall-hung boiler be repaired?

Can the motherboard of Robello wall-hung boiler be repaired?

The motherboard of Robello wall-hung boiler can be repaired.

It’s just that the manufacturer does not provide the parameters of each component of the circuit board because of technical confidentiality, which is confusing. The most prone to problems are chip transistors. An electrical maintenance technician with certain experience can analyze the circuits between adjacent ones to obtain some parameters. But it's more troublesome. If the parameters are accurate, you only need to replace a transistor that costs a few cents and it will be repaired. If you want to replace a motherboard, it costs a few hundred yuan for a domestic one or two or three thousand for an imported one. Do not ask after-sales service to replace it. They often charge an additional price of five hundred to one thousand yuan.

Generally speaking, the components on the main board of the wall-mounted boiler are not allowed to be disassembled, replaced and repaired, but the entire main board must be replaced. If the wall-hung boiler is damaged or otherwise malfunctions due to repairs on components on the main board, the manufacturer's warranty may be lost.

The wall-mounted boiler is a device that integrates gas, electricity, water and many other items. For safety reasons, it is better not to make any changes. It is recommended that the repair be carried out by a qualified after-sales service department.

What will happen if the mainboard of the wall-mounted boiler is broken?

1. If the main board of the wall-hung boiler is broken, ignition failure will occur, and the temperature control cannot be used. It may also directly cause continuous combustion, high temperature failure and other factors;

2. The wall-hung boiler is a gas wall-hung boiler. The abbreviation, the full name is "gas wall-mounted heating furnace", which is a water heater using natural gas as energy. It has various safety protections such as anti-freeze protection, anti-dry protection, accidental flameout protection, over-temperature protection, and water pump anti-seizure protection. measure.

Detailed explanation of the electronic components of the wall-mounted boiler motherboard?

1. Adjust the operation of various components in the wall-hung boiler. ​

2. Control the boiler combustion state. ​

3. Record the operating parameters (temperature, time period, operating mode).　　

4. The circuit board is divided into low-voltage part and high-voltage part. The low-voltage part is responsible for control and regulation, and the high-voltage part is responsible for ignition. The names of circuit boards include: circuit board, PCB board, aluminum substrate, high frequency board, thick copper plate, impedance board, PCB, ultra-thin circuit board, ultra-thin circuit board, printed (copper etching technology) circuit board, etc. Circuit boards make circuits miniaturized and intuitive, and play an important role in mass production of fixed circuits and optimizing the layout of electrical appliances. The circuit board can be called a printed circuit board or a printed circuit board, and its English name is (Printed Circuit Board) PCB.

What happens if the mainboard of the wall-mounted boiler is broken?

1. Aging of circuit components

After long-term operation, the circuit components on the mainboard of the wall-mounted boiler are prone to aging, resulting in changes in resistance values, thus affecting the normal operation of the mainboard. We need to replace circuit components to ensure the normal operation of the motherboard.

2. Mainboard power supply failure

The power supply of the wall-mounted boiler's mainboard is the key to ensuring its normal operation. If the mainboard power supply fails, the mainboard will not work properly. We need to repair or replace the motherboard power supply to ensure normal power supply to the motherboard.

3. Short circuit of the main board circuit

Short circuit of the main board circuit of the wall-mounted boiler is also one of the common causes of main board failure. It is mainly caused by poor circuit contact, aging circuits and other reasons. We need to inspect and repair the lines to ensure their normal operation.

How to set up the motherboard of the Shenzhou wall-hung boiler?

After replacing the motherboard of the Shenzhou wall-mounted boiler, the setting steps are as follows:

First, turn off the power of the wall-mounted boiler and wait a few minutes to ensure that the circuit is completely disconnected.

Then, open the wall-hung boiler casing, find the main board and remove it. Install the new mainboard onto the boiler and connect all the wires.

Turn on the power supply of the wall-hung boiler and start the wall-hung boiler.

Enter the wall-mounted boiler setting menu and select "System Settings" or "Parameter Settings". According to the wall-mounted boiler model and specific conditions, set relevant parameters, such as time, temperature, pressure, etc.

After the settings are completed, save the settings and exit the menu.

Finally, close the boiler housing and tighten the screws.
