| failure. |
| •Auger motor hums but does not turn. | •Auger can’t turn. Circuit board |
|
| has not yet shut it down. |
| •Unit is shut down. | •Circuit board has shut ice |

| auger motor amp draw. Check |
|
| for cause of high amp draw, |
including bearings, gear motor condition and scale on auger and in evaporator.
No ice, auger motor is turning.
•Low pressure control open.
•No power to circuit board.
•Circuit board gear motor relay will not close.
•Compressor contactor coil is open. •Compressor will not start.
•Auger not turning due to: motor failure; auger relay failure on circuit board; or or gears stripped. Check drive train.
•TXV restricted or not metering. Check bulb temperature. •Lack of refrigerant, check for
leak.
•Check for a restricted system.
•Check harness
•Hi or low pressure cut outs open.
•Check/replace board.
