Understanding the Problem
DC97-07618A is an OEM board designation commonly seen on Samsung appliance PCBs. Without the appliance model it’s not possible to definitively state which exact appliance uses this board, but boards with this prefix are typically main control or dispenser/ice/PCB modules in refrigerators or similar household appliances. When this PCB fails, the appliance may lose control of functions (no display, no compressor/defrost cycles, no dispenser/ice operation, or intermittent behavior). Control board failures can be caused by age, power surges, water/ice intrusion, or damaged components on the board (burned traces, failed capacitors, blown fuses). Troubleshooting focuses on visual inspection, checking power and connectors, verifying related sensors and outputs, and measuring voltages at key board terminals before replacing the board. Always verify the part number stamped on the board and cross-check with your appliance model before buying a replacement.
Common Symptoms
Appliance won't respond or runs erratically; no display or control lights; compressor or fan won't start though power is present; dispenser or ice maker stops working; intermittent operation that resets when board is tapped or briefly disconnected.
Common Causes
- Failed electronic components on the PCB (capacitors, diodes, MOSFETs, regulators)
- Water/ice intrusion or corrosion causing short circuits
- Power surges or lightning damage to control electronics

Helpful Repair Tip
Confirm the board is the problem by: (1) visually inspecting for burned components or swollen capacitors, (2) checking incoming mains voltage and ground to the board, and (3) measuring expected output voltages to the compressor, motors or displays. If outputs are dead while inputs are present, the PCB is likely faulty.
Frequently Asked Questions
How can I be sure DC97-07618A is the part that needs replacement?
Start with a visual inspection for burned components, scorch marks, or swollen capacitors. Verify the board is receiving correct incoming power with a multimeter. Then measure key output voltages while the appliance is trying to perform the failing function (compressor start, motor run, display power). If inputs are present but outputs are absent or incorrect, the PCB is likely the culprit. If unsure, capture the appliance model number and compare the board number on the PCB to OEM parts listings or consult a trained technician.
Can I replace the DC97-07618A myself and how much will it cost?
If you’re comfortable working with mains electricity and appliance electronics, you can replace the board yourself: unplug the appliance, take photos of wiring, label connectors, remove the old board and install the new one, then reconnect and test. Costs vary widely by appliance model — the PCB itself (DC97-07618A) typically ranges from a moderate to high price depending on availability and whether it’s OEM or aftermarket. If the failure was caused by a surge or another damaged component, replacing only the PCB may not fix the root cause. If you’re not experienced, hiring a technician is safer and ensures correct diagnosis and installation.
