1/3 HP compressors. 220V. REF. Overload Protector
This device is an OL-006 Overload Protector, a critical safety component for refrigeration and air conditioning compressors.
Technical Specifications
- Model/Part Number: OL-006.
- Horsepower (HP) Rating: Specifically designed for 1/3 HP compressors.
- Voltage/Frequency: Rated for 220V AC at 50/60Hz.
- Type: External “plug-on” thermal overload protector.
- Terminals: Features standard male spade connectors for easy wiring to the compressor’s power leads.
Core Function & Safety
The primary job of this overload is to act as a fail-safe switch for the compressor motor:
- Thermal & Current Protection: It contains an internal bimetallic strip that monitors both the temperature of the compressor and the electrical current it draws.
- Circuit Interruption: If the compressor draws excessive current or begins to overheat (due to a mechanical stall or high ambient temperatures), the bimetal strip “pops” open.
- Safety Shutdown: This instantly cuts power to the compressor to prevent it from burning out its internal windings or causing an electrical fire.
- Automatic Reset: Once the compressor and the overload part cool down to a safe level, the bimetal strip resets, allowing the compressor to attempt another start.
Common Failure Symptoms
If this part is faulty or “tripping” frequently, you may notice:
- Clicking Sound: A repetitive “click” every few minutes from the back of the refrigerator as the overload trips and resets.
- 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.
