💡 What causes an air compressor pressure switch to cycle too frequently?
A damaged diaphragm often fails to hold seal pressure, causing the motor to kick on way too fast for regular shop tasks.
- Cracked internals lose their bite under load, forcing the motor to restart faster than your normal garage workflow expects.
- Inspecting the contact springs and wiring terminals directly usually spots the leak causing those rapid start stops instantly.
- Swapping in a fresh calibrated unit locks the target pressure down and keeps your equipment handy for busy weekend jobs.
