APPLIANCE CIRCUIT BOARD REPAIR
Refrigerator Control Board Repair
The refrigerator control board is responsible for regulating temperature, defrost cycles, fan operation, and compressor activity.
When it fails, cooling efficiency drops, defrost cycles may not initiate, or the unit may completely lose power.
Refrigerator control board failures are often caused by power supply issues, such as burnt capacitors or faulty voltage regulators, leading to intermittent power loss.
Compressor relay failures are another common problem, where overheated relays fail to switch on or off the compressor, resulting in inconsistent cooling. Issues with the defrost timer and heater circuits can lead to ice buildup in the freezer, while faulty temperature sensors, often thermistors, can cause incorrect temperature readings.
Communication errors between the main board and the user interface panel can also cause malfunctioning controls or unresponsive displays.
Our repair process typically includes replacing defective surface-mount components like diodes, transistors, and IC chips, and re-soldering broken relay contacts that control the compressor and evaporator fan.
We service all types of refrigerators, including top/bottom freezer models, side-by-side and French door units, built-ins, smart Wi-Fi connected refrigerators, and commercial refrigeration units.
Oven & Range Control Board Repair
The control board in ovens and ranges manages power distribution, heating element activation, and user interface controls.
Failures can result in unresponsive keypads, temperature instability, or complete shutdowns.
One of the most common issues in ovens and ranges is heating element relay failure, where the bake/broil elements either fail to heat up or overheat due to faulty relays. Defective TRIACs and SSRs (solid-state relays) cause inconsistent heating cycles, and sensor errors from thermistors lead to incorrect temperature readings. High-voltage power failures, often due to burnt traces or blown MOVs (metal-oxide varistors), can lead to total board failure. In modern ovens, communication errors with smart features, like Wi-Fi modules, are common and disrupt app connectivity.
We address these issues by replacing failing TRIACs, relays, and MOSFETs that control heating, and reworking corroded PCB traces affected by heat and moisture. For smart ovens, we reprogram or replace microcontrollers (MCUs) to resolve software-related failures, bringing your appliance back to full functionality.
Our services cover electric, gas, and induction ranges, built-in wall ovens and stovetops, professional-grade ovens, and smart connected ranges.
Washer & Dryer Control Board Repair
Control boards in washers and dryers regulate motor speed, water flow, drum rotation, and drying cycles.
When the control board fails, machines may stop mid-cycle, fail to start, or display incorrect error codes.
Motor control failures are one of the most common issues, where burnt MOSFETs or failed motor drivers (IGBT transistors) cause the drum motor to stall. Inverters and drive circuit failures disrupt variable-speed motor operation due to faulty PWM circuits. Water level and pressure sensor errors are often caused by defective pressure transducers or broken I2C sensor circuits, resulting in overfilling or underfilling. Heating element and thermostat failures, such as open circuits in heating relays or blown thermal fuses, affect drying efficiency. Additionally, malfunctioning door lock and safety sensors can prevent the appliance from starting or unlocking the door.
We restore proper function by replacing high-current relays for motor and heating control, reflowing weak solder joints on components subject to vibration, and reprogramming EEPROM chips to fix corrupted firmware. This allows your washing machine or dryer to run smoothly and efficiently again.
We service all types of washers and dryers, including top-load and front-load machines, electric and gas dryers, commercial laundry equipment, and smart washers/dryers with integrated features.
Microwave Control Board Repair
Microwave control boards regulate magnetron power, turntable motors, and keypad interfaces. If the control board fails, the microwave may not heat, the turntable may stall, or the keypad may become unresponsive.
Common issues include high-voltage relay failures, where the magnetron, transformer, or cooling fan stop functioning due to worn-out relays. Keypad and touchscreen malfunctions occur when the flex-ribbon connectors break, preventing proper communication between the user interface and the control board.
Inverter and power board issues, such as defective high-voltage diodes, failed triacs, or blown capacitors, lead to erratic heating cycles. Turntable and fan circuit failures are typically caused by faulty stepper motor drivers, which prevent smooth turntable rotation or airflow.
We address these failures by replacing high-voltage diodes and relays, re-soldering broken PCB traces and ribbon connectors, and fixing capacitor leaks and voltage regulators to eliminate power fluctuations.
Our service ensures your microwave heats evenly and operates properly.
We service all types of microwaves, including countertop and built-in models, over-the-range microwaves, commercial-grade units, and smart microwaves with touchscreen controls.
Dishwasher Control Board Repair
Dishwasher control boards regulate water flow, pump operation, and heating cycles.
Failures in the control board can cause improper drainage, drying issues, or cycle interruptions.
Common problems include pump relay and drainage circuit failures, where faulty relays lead to stagnant water or improper drainage. Heating element control failures are caused by defective thermostat circuits or high-limit switches, disrupting the sanitizing and drying functions. Cycle timing and sensor errors occur when clock generators or microcontrollers fail to communicate with sensors, leading to incorrect wash cycles. Unresponsive buttons or display failures are typically caused by faulty capacitive touch panels or damaged LED drivers.
Our repair service includes replacing defective relays and optoisolators for pump and heating control, reworking corroded traces in moisture-exposed boards, and updating firmware on EEPROM chips to resolve sensor miscommunication.
These repairs restore proper washing and drying functions to your dishwasher.
We service all types of dishwashers, including built-in, portable, and countertop models, as well as smart dishwashers with Wi-Fi control and commercial dishwashing equipment.
