3.3.3 Controls Breaker
There is a small pop-out breaker protecting the control system components. This isn’t used during normal operation. If it
were to pop out, try pressing it back in. If it fails to stay in, there may be failure in one of the controls which is shorted, or
is drawing excessive current. This would likely indicate the need for an RMA repair. Contact Marway support.
