Ingersoll Rand T30: What to Do If Your Compressor Doesn’t Unload When Stopped
What does it mean if the compressor doesn't unload when stopped?
If your T30 doesn't unload when stopped, air remains trapped in the system, creating extra startup load on the motor and potentially causing hard starts or tripped overloads. This can lead to unnecessary wear and electrical issues.
Possible cause and solution
1. Leaking or maladjusted centrifugal pilot valve (or defective O-ring)
A faulty pilot valve or damaged O-ring can prevent the system from properly venting air when the compressor shuts down.
-
Solution: Inspect the centrifugal pilot valve for leaks or incorrect adjustments. Replace worn or defective O-rings and make sure the valve is set and operating correctly to allow proper unloading.
For instance: If your valve is damaged or no longer adjustable, we offer pilot valve replacements for T30 compressors. Just double-check your model and part number before ordering.
Final tip
Address unloading problems right away to avoid hard starts and protect your T30’s motor and starter from unnecessary strain.
Safety first: Before starting any repairs, make sure the isolation switch is turned off or the wiring is completely disconnected from the power supply. Release all air pressure from the receiver and disconnect the unit from any external air sources. Taking these simple steps helps prevent accidents and keeps you safe while working on your compressor.
