In today's modern world, home appliances are not just a collection of mechanical parts; Rather, they are intelligent and complex systems that operate under the command of an electronic mastermind. This mastermind is the "electronic board". Failure of this vital part can disrupt the overall performance of the device and make daily life a challenge. Considering the high price of household appliances and the lack of fabric parts in the market, repairing the electronic board of household appliances in Tehran has become one of the most basic needs of citizens. In this regard, Falahi Engineering Technical Services is the flagship of providing specialized services in the field of troubleshooting and repairs of electronic circuits, using the latest knowledge and advanced equipment. In this article, we intend to explain to you the hidden corners of these sensitive parts, the importance of basic repairs and the difference between professional services.
The position of the electronic board in modern household appliances
You may be wondering why the electronic board is so important? In the past, home appliances operated with mechanical timers and simple switches. But today, the electronic board (PCB) is responsible for the precise control of all processes. From adjusting the temperature of the refrigerator with 10 degrees accuracy to controlling the engine speed of the washing machine and scheduling the washing of the dishwasher, all are managed by this part. Repairing the electronic board of household appliances in Tehran requires a deep understanding of the working logic of these parts.
The electronic board receives information from various sensors (such as temperature, water level, or weight sensors), processes them, and then sends the necessary commands to actuators (such as motors, drain pumps, or solenoid valves). The smallest disturbance in this processing path can lead to a complete stop of the device. The expert team of Falahi Engineering Technical Services is able to identify the most complex logical and circuit defects with a complete understanding of the schematic and architectural drawings of these boards.
Common symptoms of electronic board failure
Determining whether the problem is with the board or the mechanical parts is the first step in the repair process. Many unskilled repairmen mistakenly replace healthy parts when the root of the problem is in the board. In the process of repairing the electronic board of household appliances in Tehran which is done by our collection, it is important to pay attention to the following symptoms:
- The device does not turn on: If the input power is healthy, but the device does not show any reaction, there is a possibility that the power supply part of the board is burnt.
- Displaying error codes (Error Codes): Many modern devices show a specific error code on the display if there is a problem with the board.
- Irregular operation: For example, the washing machine drains water but enters the washing phase. It doesn't work, or the refrigerator works at all.
- Burning smell: Smelling the smell of burnt wire or plastic from the device panel indicates the burning of parts on the board such as capacitors or resistors.
- Sudden shutdown: The device turns off during operation for no apparent reason.
Technicians of Falahi Engineering Technical Services analyze these symptoms by using accurate troubleshooting tools and go directly to the faulty part of the board to avoid wasting time and money.
Specialized repairs of the washing machine range
Washing machines, especially inverter and direct drive models, have very advanced boards. These boards are responsible for controlling the engine speed at high (dryer) and low (washing) speeds. Power fluctuations or panel dehydration are the main enemies of the washing machine. Electronic board repair of household appliances in Tehran in the field of laundry, requires special expertise in which Falahi Engineering Technical Services excels.
Problems such as not draining water (while the pump is healthy), not heating the water (while the element is healthy), or severe vibration due to engine rpm imbalance, can all be rooted in the failure of components such as triacs, relays, and driver ICs on the board. At Falahi Collection, instead of replacing the entire board, which costs a lot, we restore the fabric board of your device at the lowest cost by replacing defective electronic parts and repairing broken copper paths. Keeping the main board of the device guarantees full compatibility with other parts.
Super-specialized refrigerator board and side-by-side repairs
Refrigerators are devices that must work 24 hours a day, so their range is under constant pressure. Failure of the refrigerator board can be catastrophic and lead to spoilage of food. In household appliance electronic board repair service in Tehran, our focus is on speed and accuracy in troubleshooting refrigerator boards. Refrigerator boards are responsible for controlling the compressor, fans and defrost system.
If your refrigerator won't cool but the motor is fine, or if it's frosting a lot, the relays for the compressor or the on-board defrost element control circuit are probably faulty. Falahi Engineering Technical Services having a complete archive of original electronic parts, is able to repair all types of American, European and Asian refrigerators. Repairing the "inverter" part in new refrigerators that have variable speed compressors is one of our most complex services that requires high-level electronic engineering knowledge.
Repairing the dishwasher board; Attention to detail
Dishwashing machines are a combination of water, heat and detergents, and their electronic board must perform perfectly in a humid and warm environment. Moisture penetration into the board compartment or power fluctuation can cause the failure of the microcontroller IC or power supply components. Requests for repairing the electronic board of household appliances in Tehran are increasing in the dishwasher sector.
Problems such as not heating the water, not spraying water by the arms, or water remaining on the bottom of the device, are all managed by the board. The Falahi Engineering Technical Services team solves the problem by carefully checking the steering circuits and the power of the dishwasher board. We also restore the protective coatings (Conformal Coating) on the board that are removed during repair so that the board remains moisture resistant.
Why is repairing the board better than replacing it?
In the current economic conditions, cost management is very important for households. When a device's board fails, traditional dealers or repairmen usually offer to replace the entire board. The price of a new board, depending on the brand and model, can be very expensive and sometimes include half of the price of the whole device. However, the approach of Falahi Engineering Technical Services in providing services of repairing the electronic board of household appliances in Tehran is based on "repair", not replacement.
More than 90% of electronic boards can be repaired. The failure is usually related to one or more small components (such as capacitors, resistors, relays or transistors) whose price is very small compared to the entire board. By correctly diagnosing and replacing the same small parts, the board continues to work with the same original quality. This work not only has a significant economic benefit for the customer, but also prevents the entry of electronic waste into the environment. Our expertise in repairs preserves your capital.
Troubleshooting process with advanced laboratory equipment
Electronic repairs are not possible with guesswork. Falahi Engineering Technical Services is equipped with the most advanced electronic laboratory for repairing the electronic board of household appliances in Tehran. We use tools such as oscilloscopes to observe voltage waveforms, precision multimeters to measure component values, variable power supplies, and professional heaters to solder SMD components.
Using simulator testers is one of our strengths. These testers allow us to power up the board outside of the device and on the desktop and simulate its performance in real-world conditions. In this way, before reinstalling the board on the client's device, its complete health is ensured. This level of technical accuracy is what distinguishes us from other repair shops.
The role of power fluctuations in board failure and prevention strategies
One of the main reasons for referrals for repairing the electronic board of household appliances in Tehran is damage caused by city electricity fluctuations. Electronic components are highly sensitive to voltage changes. A sudden increase in voltage (Spike) can burn varistors (voltage protectors) and fuses on the board, and in more severe cases, damage the main IC (CPU).
Experts of Falahi Engineering Technical Services always advise customers to use standard electrical protectors or stabilizers (voltage stabilizers) for the whole house. However, don't worry if your board experiences power surges. The input protection circuits of most boards are designed to burn themselves out so as not to damage the main processor. We revive the burnt board by repairing the power supply and protective circuits.
Repairs of inverter boards; The pinnacle of technology
New home appliances mostly use inverter technology to reduce energy consumption. Inverter boards have a more complex structure than conventional boards and include IPM power modules that convert DC power into three-phase variable frequency power for the motor. repairing the electronic board of household appliances in Tehran in the inverter sector, requires high engineering knowledge that is found in few places.
The team of Falahi Engineering Technical Services is able to diagnose and repair these expensive boards by mastering inverter technology. Repairing IPM modules and gate driver circuits is our specialty. Many repairmen refuse to accept these boards due to their complexity, but we confidently accept the responsibility of repairing them and guarantee their performance.
The importance of using original spare parts
The quality of the parts replaced during the repair process determines the longevity of the board after repair. The electronic market is full of fake and low-quality Chinese parts that look similar to the original parts, but do not have the necessary performance and durability. Using these parts in the process of repairing the electronic board of household appliances in Tehran can cause further damage and even more damage to the device.
At Falahi Engineering Technical Services, we are committed to using original and grade A electronic components. High thermal tolerance capacitors, real amp relays and original programmed ICs are the components we use in our repairs. This commitment to quality has made our customers use their devices for years without any problems after repair.
Air conditioner and split board repairs
With the arrival of the hot season, the failure of the air conditioner is one of the main concerns of the citizens of Tehran. The air conditioner board is responsible for controlling the compressor and the external fan. If the board does not command, the cooler will only blow hot air. Electronic board repair of household appliances in Tehran includes specialized repairs of condenser boards and internal panels of air conditioners.
Problems such as the cooler not turning on, the remote control not working (due to the optical failure of the receiver on the board) and the panel freezing, can all be solved by the experts of Falahi Engineering Technical Services. We restore the cooling performance of your device by carefully checking the relay command circuits and temperature sensors (thermistor).
Programming and reprogramming ICs (Microcontrollers)
Sometimes the hardware of the board is fine, but the software or internal program of the microcontroller IC is corrupted (so-called program jump). This problem causes strange and irrational behavior of the device. One of our specialized and distinctive services in the field of electronic board repair in Tehran is the possibility of IC reprogramming.
Falahi Engineering Technical Services is able to reprogram memory IC and microcontroller board by accessing dump files and original software of different brands. This high-level technical capability enables us to recycle boards that others have deemed unrepairable.
