What 40 9 40
actually means.
On Classic (BI and CL) and Designer models with a dispenser, 40 9 40 means the dispenser was active for its maximum run time. A held paddle, a stuck switch or a dispense that never ends can bring it on.

What to do when 40 9 40 shows on the ice makerKind of codeDispenser and auger
The dispenser was asked for ice and could not deliver it: the auger motor stalled against a frozen block, the flap at the bottom of the chute stayed shut, or the paddle switch never told the control it was pressed. Emptying the bin and thawing the chute come before the auger motor, the door flap solenoid or the switch is replaced.
Usually leads toIce dispenser and auger repair
The auger, its motor, the crusher, the chute flap and the paddle switch that move ice from the bin to your glass, or push soft nugget ice up and out, checked and repaired when the ice stops coming.
Shows up asIce Dispenser Not Working
The ice dispenser not working means you press the paddle and nothing comes, or the motor hums without ice, or only a few chips fall while the bin behind the door is full.
