| Switch, conveyor reversing | Check continuity between switch terminals. |
|
| Replace switch as needed. |
| Oven control | If there is supply voltage to the motor, and the |
|
| motor, capacitor, and reversing switch check |
|
| good, replace the oven control. |

|
| 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. |
