The ignition control requires a minimum of 0.8 DC microamps to prove flame. To check flame sensing operation, connect a digital multimeter (capable of measuring DC microamps) between the “ground” terminal on ignition control and the ground lead.

If there is a read-out on the control, set the control to maximum temperature (see installation operations manual for temperature adjustment). With the control set at maximum temperature, check for supply voltage at mercury contactor. If there is voltage at the mercury contactor, proceed to “mercury contactor” for next check. If there is no voltage at the mercury contactor, trace wiring back to the oven control. If there is no voltage output at the oven control, check the read-out on th

Improper ventilation or lack of preventive maintenance may cause this. Also, most of the problems listed under “Oven will not heat” can cause intermittent failure.

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.
