Why won't my AIRMAC Air Compressor motor start?
- AAngela TuckerAug 19, 2025
Several factors can prevent your AIRMAC Air Compressor motor from starting. First, ensure the pressure switch is turned on. If the air receiver tank pressure is above the cut-in pressure, no action is needed. Check the electricity supply, including fuses, circuit breakers, switches, and wiring. A faulty pressure switch or star-delta starter could also be the culprit, requiring repair or replacement. For 415V supplies, verify voltage on all three phases. Low supply voltage can be resolved by upgrading the power supply circuit or disconnecting other devices on the same circuit. Avoid using an extension lead; instead, use a longer, larger diameter air hose. If the motor has a thermal overload switch tripped (240V), allow it to cool and manually reset the switch.
