1/4 HP. 220V. 50/60HZ. Compressors. REF. Overload Protector. OL-005
This device is an OL-005 Overload Protector, a critical safety component used in refrigeration and air conditioning compressors.
Technical Specifications
- Model/Part Number: OL-005.
- Horsepower (HP) Rating: Specifically designed for 1/4 HP compressors.
- Voltage/Frequency: Rated for 220V AC at 50/60Hz.
- Type: External “plug-on” thermal overload protector.
- Terminals: Features a standard female spade connector for easy wiring.
Core Function & Safety
The primary job of this overload is to act as a fail-safe fuse for the compressor motor:
- Thermal Protection: It contains a bimetallic strip that senses the temperature of the compressor.
- Current Sensing: If the compressor draws too much current (amperage) or begins to overheat, the bimetal strip “pops” open.
- Circuit Interruption: This instantly cuts power to the compressor motor to prevent it from burning out its internal windings.
- Automatic Reset: Once the compressor cools down to a safe temperature, the bimetal strip resets, allowing the compressor to attempt another start.
Common Signs of Failure
If this part is faulty or “tripping” frequently, you may notice:
- Clicking Sound: A repetitive “click” every few minutes coming from the back of the refrigerator.
- No Cooling: The compressor fails to run even though the internal fridge lights are on.
- Short Cycling: The compressor turns on for a few seconds and then shuts off immediately.
