Terminals are normally closed. If open, reset and test for proper operation. If thermostat will not hold, and the control box temperature is not exceeding 140°F (60°C), replace thermostat. Relay, oven control Check for line voltage to the relay coil. If voltage is not present, trace wiring back to the hi-limit thermostat. If voltage is present, check to insure contacts are closing. Replace relay as needed. Control transformer Check for line voltage supply to the primary of the control transformer. If no voltage is present, trace wiring back to the oven power relay. If voltage is present, check for 24VAC at the transformer secondary. If there is primary voltage, but no secondary voltage, replace control transformer. Conveyor motor Check for line voltage supply to the conveyor motor at wire #28 to neutral. If no voltage is present, trace wiring back to the oven power relay. If voltage is present and the motor will not run, check the motor windings for opens or shorts. WITH POWER OFF: Check the motor windings as follows: Grey to black 116 ohms Grey to brown -116 ohms Brown to black -230 ohms Capacitor, conveyor motor Check for shorts or grounds. Replace capacitor as 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 supply voltage to the motor. And the motor, capacitor, and reversing switch check good, replace the oven control. Conveyor motor runs, but there is NOTE: Display will indicate “Belt jam” no speed display Oven control Check for output voltage from the 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. Low Profile – 1600 Series Adv Dig Electric S.M. – Int’l 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 readings should be approx. 20 – 525 Hz. If these readings are not achieved, replace the 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. Low Profile – 1600 Series Adv Dig Electric S.M. – Int’l REMOVAL, INSTALLATION & ADJUSTMENTS MODEL SERIES 1621-000-EA, 1628-000-A, 1629-000-A CAUTION! BEFORE REMOVING OR INSTALLING ANY COMPONENT IN THE IMPINGER OVEN BE SURE TO DISCONNECT ELECTRICAL POWER AND GAS SUPPLY. AIR PRESSURE SWITCH – REPLACEMENT A. Remove control panel top. B. Disconnect wires from switch making note of wire number and location for reinstallation. C. Remove air tube from switch assembly. D. Remove switch from control box. E.

To increase sensitivity, turn screw counter-clockwise; to decrease sensitivity, turn screw clockwise. CONVEYOR DRIVE MOTOR – REPLACEMENT A. Shut off power at main breaker. B. Remove conveyor. C. Remove control panel top and front cover. D. Disconnect wiring from motor and mark for reassembly. E. Remove sprocket from motor shaft. F. Remove 4 screws and remove conveyor motor and mounting bracket. G. Remove mounting bracket from conveyor motor assembly. H. Reassemble in reverse order. CAPACITOR, CONVEYOR MOTOR – REPLACEMENT A. Shut off power at main breaker. B. Remove control box cover and front panel. C. Discharge capacitor before removing wires. Mark wires for reassembly. D. Remove mounting screw and remove capacitor. E. Reassemble in reverse order. REVERSING SWITCH – REPLACEMENT A. Shut off power at main breaker. B. Remove control box cover and front panel. C. Disconnect wiring from reversing switch and mark for reassembly. D. Remove mounting nut and remove reversing switch. E. Reassemble in reverse order and check system operation. REVERSING CONVEYOR DIRECTION A. Shut off power at oven switch. B. Set reversing switch in the other position. C. Turn oven “on” and check for proper operation. FUSEHOLDER – REPLACEMENT A. Shut off power at main breaker. B. Remove appropriate control box cover. Low Profile – 1600 Series Adv Dig Electric S.M. – Int’l C. Remove 2 wires, note wire number and location. D. Remove locknut on backside of fuse holder and push out. E. Reinstall in reverse order and check system operation. THERMOSTAT, HIGH LIMIT, OVEN CAVITY – REPLACEMENT A. Shut off power at main breaker. B. Remove appropriate control box cover. Remove motor cover and remove oven back to access high limit thermostat sensing bulb. C. Remove wires from thermostat, note wire numbers for reinstallation. D. Remove mounting nut f...
