When your Murray mower won't start, there may be several reasons. If the battery and starter are fine then you will need to replace the starter solenoid. The starter solenoid is the component that links the ignition, starter and battery all together safely. Sometimes the starter solenoid will have a shorted out wire and you will need to replace the starter solenoid to get your Murray mower running again.
