| needed. |
|
| WARNING: Capacitor has a stored charge, |
|
| discharge before testing. |
| Switch, conveyor reversing | Check continuity between switch terminals. Replace |
|
| switch as needed. |
|
|
|
| Oven control | If there is 120VAC supplied to the motor, and the |
|
| motor, capacitor, and reversing switch check good, |
|
| replace the oven control. |
Conveyor motor runs, but | NOTE: Display will indicate |
|
there is no speed display | “Belt Jam” |
|
| Oven control | Check for output voltage from oven control to hall |
|
| effect sensor (sensor is located in conveyor motor). |
|
| Measure voltage at the motor connector, red wire |
|
| and yellow wire. Voltage should be approx. 10VDC. If |
|
| no voltage is present, trace wiring back to oven |
|
| control. If there is no voltage present at the oven |
|
| control, replace the oven control. |
| Conveyor motor | If there is voltage supplied to the hall effect sensor, |
|
| check for a frequency output from the hall effect |
|
| sensor. Measure frequency across the yellow and |
|
| white wires at the motor connector. Frequency |
|
| reading should be approx. 25 – 100 Hz. If these |
|
| readings are not achieved, replace conveyor motor. If |
|
| the readings are achieved, proceed. |
| Oven control | If the hall effect sensor readings are correct, but |
|
| there is no speed indicated on the display, replace |
|
| the oven control. |
