Ensure the electrical safety and mechanical longevity of your compressor with the Samsung Air Conditioner OLP (Overload Protector) DB47-20001U. This critical safety component is designed to monitor the temperature and current draw of the compressor motor. If the compressor begins to overheat due to high ambient temperatures, a refrigerant leak, or an electrical surge, the OLP automatically breaks the circuit to prevent the motor windings from burning out. Once the compressor cools down to a safe level, the protector typically resets, allowing the system to restart. If your outdoor unit is hums but the compressor fails to kick in, or if the compressor stops running shortly after starting, the OLP may be tripped or faulty.

The DB47-20001U is a precision-calibrated bimetallic switch housed in a heat-resistant casing. It is engineered to react to specific thermal and electrical thresholds matched exactly to the compressor's specifications. This genuine OEM part ensures that your system remains protected against catastrophic mechanical failure.

Installation / Replacement Instructions

Warning: Replacing the OLP involves working with high-voltage components and the compressor terminal. This should be performed with extreme caution or by a qualified technician.

1. Safety First: Turn off the air conditioner and completely disconnect the power at the outdoor disconnect box or main circuit breaker. Wait 10 minutes for capacitors to discharge.

2. Access the Compressor: Remove the top and side panels of the outdoor condenser unit. Locate the compressor and remove the sound blanket or insulation if present.

3. Remove the Terminal Cover: Unscrew the nut or release the spring clip holding the plastic terminal cover on the top or side of the compressor.

4. Locate the OLP: The DB47-20001U is typically mounted directly against the compressor housing, held in place by a spring clip, or wired in series with the Common (C) terminal under the cover.

5. Disconnect the Wiring: Note the position of the wires. Carefully pull the spade connectors off the old OLP using needle-nose pliers. Do not pull on the wires themselves.

6. Swap the Protector: Remove the old unit and snap the new DB47-20001U into the mounting clip. Ensure it is seated firmly against the metal shell of the compressor to accurately sense the housing temperature.

7. Reconnect and Close: Reattach the wiring connectors firmly. Replace the terminal cover and secure it with the nut or clip.

8. Reassemble and Test: Reinstall the outdoor unit panels and restore power. Monitor the compressor to ensure it starts smoothly and continues to run without premature tripping.

Compatible with select Samsung outdoor units, this OEM-quality overload protector restores the essential safety logic and hardware protection originally designed for your system.
