What to do if the green lamp on the Arjo AtmosAir 4000 pump doesn't light?

If the green lamp on the pump isn't lighting up, start by checking if the power cord is securely plugged in. Also, verify that the wall outlet isn't controlled by a switch and that the circuit breaker hasn't tripped. If these steps don't resolve the issue, it's possible that the power cord or switch is damaged.
