Now let's talk about what to do if your Impinger oven seems to be malfunctioning. Before you make a service call, there are a few things you should check out. You might be able to solve the problem yourself or at least narrow it down. We'll look at troubleshooting in terms of the symptom you've observed and what might be causing it.
If you go to turn on the oven at the beginning of the work day and it did not respond by heating up. Always suspect the easy stuff first. Is the oven plugged in tightly? Check the temperature indicator light, does it show that the oven is heating? If not, see if the temperature control knob is set to the right temperature. You may then need to hit the high temperature reset button. If the thermostat is set right, see if the main fan is working by checking for air movement. If there's no air movement, the fan isn't working, so check the main circuit breaker and the main fan fuses on the oven. If you find a bad fuse, replace it. If the fuse is okay, there's nothing more that you can do your authorized Lincoln service agent must be contacted.
Burnt products result from too high of a temperature, too long of cooking time, or improperly installed columnating plates or air return panels. First see if all the fingers are installed properly and the columnating panel holes line up with the holes in the finger covers. Then check the temperature control knob. If the display shows the temperature is set properly, but the products are overcooked the oven could be out of calibration. If the conveyor control knob shows that it's set properly, time it against a stop watch. Start the stop watch when the leading edge of the pan enters the oven. Stop the watch when the leading edge exits the oven. If the time or temperature need recalibrate your authorized Lincoln service agency must be contacted. In the meantime, you can try and compensate by decreasing temperature or increasing the conveyor speed.
Undercooked products could result from several things. First be sure you're not placing the food product too far into the oven cavity. The leading edge should be just at the conveyor opening and don't pull that product out of the oven too soon. Next if the temperature control knob is set properly but the products are undercooked the oven could be out of calibration. If the conveyor control knob shows that it's set properly, time it against a stop watch using the leading edge in to leading edge out method we used earlier. Again if time or temperature needs calibration, your authorized Lincoln service representative should be contacted. And of course you can compensate by decreasing the belt speed or increasing the temperature until help arrives. If time and temperature are not your problem, it could be the columnating plates or air return panels weren't installed properly. If you're still having a problem, see if the main fan is working by checking for air movement. If the fan isn't running, check the main circuit breaker and the main fan fuses. If you do all this and the oven is still not performing properly, it's time to call your authorized Lincoln service agency.
Another situation you might run into is a conveyor belt that won't move. First check to see the belt speed control was not accidentally turned all the way down. Check the drive coupling to ensure it's connected properly to the motor shaft and that the drive pan is fully seated in the notch. With the extended conveyor make sure the belting is tight against the drive sprockets. You may then need to press the black conveyor reset button. Next check your main circuit breakers and fuses. If the conveyor stopped when the oven was hot, it could be overheating. Check and clean the ventilation louvers and cooling fan covers if needed. It could also be a mechanical malfunction. With the circuit breaker off, so the conveyor belt won't start accidentally disconnect the coupling. Then gently push and pull the conveyor to see that it moves freely. If it doesn't, look for some obstruction or binding. If the conveyor moves freely, then turn the circuit breaker back on, turn the oven on, and check to see if the motor shaft is rotating. If the motor shaft won't turn, you have to call your authorized Lincoln service agency.
