Devilbiss A17374 Pressure Switch is used in air compressor systems to regulate motor start and stop action based on preset tank pressure levels. It supports the compressor respond to pressure changes and keeps air delivery stable during continuous operation.

\n

This part can fix the following symptoms:

\n

• Compressor does not react even when tank pressure falls below operating level.

\n

• Motor remains idle despite power being available to the system.

\n

• Pressure sensing does not reflect actual tank condition changes.

\n

• Control signal does not reach the motor starting circuit.

\n

• System remains inactive during normal demand cycles.

\n

Compressor Does Not Interact After Pressure Drop

\n

Quick Check: Observe tank gauge movement and confirm pressure reduction below normal activation range.

\n

Fix Suggestion: Inspect sensing port for blockage or internal calibration disruption if no response occurs.

\n

Prevention Tip: Keep air pathways clean and avoid oil contamination in sensing area.

\n

Motor Keeps Running Without Regulation

\n

Quick Check: Check if compressor continues operation after reaching maximum tank level.

\n

Fix Suggestion: Replace switch if internal control mechanism is unable to interrupt power flow.

\n

Prevention Tip: Avoid continuous use beyond rated duty cycle.

\n

Random Start Conduct During Operation

\n

Quick Check: Observe if compressor starts without clear pressure demand pattern.

\n

Fix Suggestion: Inspect internal contacts if irregular triggering is detected.

\n

Prevention Tip: Maintain stable electrical supply to reduce false activation signals.

\n

No Communication Between Switch and Motor Circuit

\n

Quick Check: Test wiring continuity from switch terminals to motor input connection.

\n

Fix Suggestion: Repair or change unit if internal electrical path is broken.

\n

Prevention Tip: Secure all terminal connections during installation and servicing.

\n

Customer Experience: Users observed that compressor cycling became more predictable after installing this switch, with reduced interruptions and improved pressure stability during long operating sessions.
