If the Snap-On POLARTEK HYBRID EEAC332 A/C machine will not power up despite having power at the switch, the issue could be related to internal components such as connections, fuses, or the control panel. The manual does not provide a specific solution for power-up failure, so detailed inspection of internal wiring and components is necessary.
