Most common
problems & fixes

Is your Samsung SMH9207ST/XAA letting you down? Don't worry, we're here to help. Check out our list of the most common problems and how to fix them yourself.

Microwave is completely dead

No functions available and microwave is incapable of operating due to absence of signal voltage at connector CN05 on the MAIN PCB.

Check for AC voltage availability in the microwave oven; check input voltage at the Noise Filter PCB Assy and ensure ≈ 120VAC on both input and output connectors of the PCB.

Microwave door opens during sensor cooking

The door opens unexpectedly during the cooking process.

Ensure that the door is securely closed before starting the cooking process.

Cooking time setting over error

The cooking time set exceeds the allowed limit for Microwave, Grill, Convection, or Combination modes.

Reset the cooking time to within the allowable limits for the selected mode.

Damper positioning error

The damper is not set to be positioned for 2 minutes.

Check the damper mechanism for obstructions and ensure proper operation.

Quick setup

Follow these easy steps to get your Samsung SMH9207ST/XAA Oven up and running in no time.

1

Safety Precautions

Before beginning the setup, ensure the oven is unplugged to avoid any electrical hazards. Always handle components carefully to prevent damage.

2

Check AC Voltage

Verify that AC voltage is available and present in the microwave oven. Check the input voltage at the Noise Filter PCB Assy and ensure ≈ 120VAC is available on both the input and output connectors of the PCB.

3

Microwave Energy Leakage Test

Pour 275±15cc of water at 20±5°C (68±9°F) in a 600cc beaker and place it in the center of the oven. Start the oven and measure the leakage using a microwave energy survey meter. Measured leakage must be less than 4mW/cm² after repair and adjustment; the maximum allowable leakage is 5mW/cm².

Innovative Design

The Samsung SMH9207ST/XAA features a unique split-board control system, unlike traditional models that house all functions on a single board. This cutting-edge design showcases Samsung's commitment to innovation.

Powerful Performance

With a cooking power of 1100 watts, the Samsung SMH9207ST/XAA is ready to heat your meals efficiently, ensuring even and quick cooking every time!

Troubleshooting

The Samsung SMH9207ST/XAA Oven has some known problems that occur often. Here are some easy to do solutions for the problems or error codes your Samsung might be giving you.

E-34

The initial value of K calculated by a weight sensor is above and under “±28” as value of HEX. Check the weight sensor for any malfunctions or calibration issues. Consider replacing the sensor if the error persists.

E-35

The value of A is “-” as a weight sensor calculates. Inspect the weight sensor for defects or calibration errors. If necessary, recalibrate or replace the sensor.

E-36

The door opens during sensor cooking. Ensure the door is securely closed during cooking. Check the door latch and switches for proper operation.

More Troubleshooting

Wiring Diagram Alert

The wiring diagram in the Service Manual for the Samsung SMH9207ST/XAA Oven is incorrect. Page 2 cannot be used for locating connectors and pins due to mislabeling. Instead, use the picture on page 3 for correct connector and pin assignments.

Diagnostic Failure Codes

The oven has several diagnostic codes such as E-11 for open circuits, E-12 for shorts, and E-13 for T1 max time errors. Each code is designed to help identify specific errors and malfunctions.

Safety Precautions

Do not attempt to measure any high voltages, including the filament voltage of the magnetron. High voltage is present during any cook cycle. Always unplug the oven and discharge the high voltage capacitor before touching components or wiring.

Troubleshooting High Voltage

Check AC voltage at the Noise Filter PCB Assy. Ensure ≈ 120VAC is present on both input and output connectors. Additionally, use a DC multi-meter to check for signal voltage at connector CN05 on the MAIN PCB.

Configuration Details

This model's configuration differs from traditional Samsung ovens. The logic and control are split between two boards, unlike previous models where all functions reside on a single board.

Microwave Oven Symptoms

A common issue with this model is the symptom of the microwave oven being 'DEAD', where no functions are available and the oven is incapable of operating.

Microwave Cooking Wattage

The microwave cooking wattage is rated at 1100 Watts, and the unit weighs approximately 52.7 lbs.

Parts and Replacement

For troubleshooting, use a DVM capable of reading both AC and DC voltages. Critical parts include the Relay Circuit Board Assy and Control Circuit Board Assy. Replacement instructions are provided for fuses and interlock switches.

Maintenance

Check out our tips to prevent many common issues and extend the life of your Samsung Oven.

Regular Cleaning

Clean the interior and exterior of the oven regularly using a damp cloth and mild detergent. This helps prevent food residue buildup, which can lead to odors and inefficient operation.

Proper Ventilation

Ensure that the oven is properly ventilated. Keep the air vents clear of obstructions to allow for adequate airflow and prevent overheating.

Inspect and Replace Filters

Regularly check the oven's filters for dirt and wear. Replace them as necessary to maintain optimal performance and to prevent grease buildup.

Check Door Seals

Inspect the door seals regularly to ensure they are clean and not damaged. Damaged seals can cause heat loss and inefficient cooking.

Avoid Overloading

Do not overload the oven with heavy or large items. This can strain the motor and other components, potentially causing damage.
