Fridge Clicking and Compressor Not Starting? Start Relay & Overload Guide
Clicking fridge and a compressor that will not start?
Repeated clicking or humming without a successful start can indicate a problem in the compressor's starting circuit. Clicking alone does not prove the start relay or overload is faulty; low voltage, wiring and compressor windings may produce similar symptoms.
What do the start relay and overload do?
Start relay: assists compressor starting in systems equipped with this type of start circuit. Overload protector: interrupts electrical operation under specified abnormal thermal or electrical conditions. Starting arrangements vary by compressor model.
Common symptoms to investigate
- Humming followed by repeated protective clicking.
- A compressor that fails to start while cooling declines.
- Repeated failed start attempts.
These symptoms are not conclusive. A qualified technician should diagnose the system before parts are replaced.
Choosing a compatible replacement
- Record the exact compressor model and photograph its rating label.
- Check rated voltage, frequency, starting arrangement and part numbers against the manufacturer specification.
- Do not assume parts with similar shapes or terminal counts are compatible.
Safety first
Disconnect power and have qualified personnel verify safe electrical conditions. Some capacitors retain charge after disconnection. Never bypass the overload or repeatedly force a compressor that does not start.
