Common Symptoms:

• Dust extractor does not activate consistently.

• Solenoid clicks without producing the expected response.

• Extractor operation intermittent during repeated starts.

• Electrical switching response appears delayed or irregular.

• Dust extractor stops responding during normal operation.

Solenoid Does Not Activate

Quick Check: Listen for solenoid activation when the extractor starts running.

Fix Suggestion: Clean affected contacts and secure connections using correct hardware.

Prevention Tip: Keep electrical connections dry and free from accumulated dust.

Intermittent Solenoid Response

Quick Check: Confirm wiring connections remain secure around the solenoid terminals.

Fix Suggestion: Test solenoid response after confirming the extractor receives power.

Prevention Tip: Check terminal tightness periodically during equipment use.

Clicking Without Extractor Response

Quick Check: Compare airflow response when the dust extractor is operating.

Fix Suggestion: Trace the switching circuit for loose electrical connections.

Prevention Tip: Keep terminal areas clear of accumulated debris buildup.

Irregular Electrical Switching

Quick Check: Look for intermittent activation during repeated extractor starts.

Fix Suggestion: Review wiring condition and correct damaged connection points.

Prevention Tip: Avoid pulling or stressing wires around solenoid terminals.
