Ingersoll Rand 54627104 Air Compressor Pressure Switch 135 PSI WWP-SS5/TS5

The Ingersoll Rand 54627104 Air Compressor Pressure Switch 135 PSI WWP-SS5/TS5 is an automatic pressure control component that helps keep an air compressor operating within its intended pressure range. By responding to changes in tank pressure, it manages motor operation and supports smooth, dependable compressor performance.

This part may resolve the following problems:

• Compressor does not restart when tank pressure drops.

• The motor continues running after the tank is full.

• The pressure switch operates inconsistently.

• Air leaks develop around the switch.

• The compressor loses automatic pressure control.

Delayed Compressor Restart

Quick Check: Lower the tank pressure and observe whether the compressor starts at the expected pressure level.

Fix Suggestion: Examine the pressure switch for worn internal contacts or pressure-sensing issues. Replace the switch if it does not respond properly.

Prevention Tip: Inspect compressor controls regularly to ensure reliable automatic operation.

Motor Runs Longer Than Expected

Quick Check: Watch whether the compressor keeps running after reaching its normal operating pressure.

Fix Suggestion: Check the pressure switch for contact wear or an internal malfunction that prevents automatic shutoff.

Prevention Tip: Test the compressor's pressure controls during routine maintenance.

Air Leak Around the Switch

Quick Check: Listen for escaping air near the pressure switch and connected fittings.

Fix Suggestion: Tighten loose fittings or replace the switch if damaged seals or threads are allowing air to escape.

Prevention Tip: Inspect threaded connections periodically and replace worn sealing components when necessary.

Inconsistent Pressure Control

Quick Check: Observe whether the compressor starts and stops at irregular pressure levels.

Fix Suggestion: Inspect the pressure switch for internal wear affecting pressure regulation. Replace the switch if normal cycling cannot be restored.

Prevention Tip: Drain moisture from the air tank regularly to help protect pressure control components.

Customer Experience: One customer mentioned that replacing the Ingersoll Rand 54627104 pressure switch helped restore dependable automatic cycling.
