| |
2 | No operation of | MCB or PCB | Check fuse F1 | |
|
|
| ||
3 | PCB will not power up | Replace MCB | ||
|
|
|
| |
4 | PCB will power up but the MCB | Verify adequate line voltage. If line voltage is | ||
adequate, MCB is damaged and needs to be | ||||

| returned to manufacturer. | |
|
|
| Verify connections to motor and the motor | |
|
|
| itself. If the motor and its connections are | |
|
|
| good, the MCB should be replace. Return | |
|
|
| MCB to manufacture with information on | |
