Will not start

Check the door lock and switch, check the input from the switch to the panel. If this is fine then check for power to the panel.remove the panel and reset the connectors to the panel.
If there is no action even after the panel is fixed with the program proceeding further, it is possible that the program controller unit is faulty.

3.Perform a Power Cycle on the unit by following the steps below:
1.Turn the unit off.
2.Unplug the power cord from the unit.
3.Wait 30 seconds, and then re-connect the power cord to the unit.
4.Turn the unit on.
5.Make a color copy by pressing the Start Copy Color button on the control panel.
4.Check the power connections.Disconnect the power cord from any power strips or surge suppressors and then plug it directly into a wall outlet.Try making a color copy by pressing the Start Copy Color button on the product control panel.If the error message displays again, temporarily move the product to a different room, or plug the power cord into a different wall outlet.

Dryer control locked light is on and dryer won't start!

Press the Reset Button for 1 minute see if it resets?
Are the lights lights DIM on the interface panel ( front of unit with buttons & lights) If so Turn power off to the dryer then you need to remove the top of the dryer lid off and locate the two ribbon cables that go between the CCU and the interface board. as well as two small ribbon cables between the two parts of the interface panel. use a paper clip or screw driver press on the center tab and reset each cable one at a time. Then turn unit back on and try it again.

if none works it could be CCU or Interface panel

Forrunner 301 won't turn on or charge

You can try various resets to see if you can get it to respond.
Have you tried plugging the unit into the wall instead of the USB
port.Do you get the Battery Charging message at any time.You can
try a soft reset.Press mode and reset.Then try to power on while
plugged in.A hard reset will delete all your data and settings from
the Forerunner.Press the Power and the Mode button until the unit
comes on and asks if you want to erase all user data.Select Yes.
If the above won't work, try a hard reset that by-passes the
confirmation screen.Press Mode, Reset and Power.

The fall may have knocked out some wiring -- open the unit (remove back panel, then remove front by taking out screws inside) and see if any of the cables to the front panel or control board came out.
