    This current is very small, about one microamp (one millionth of an amp). The Dacor re-igniter has a specifi ed minimum fl ame current that will be sensed as a fl ame of 0.5 microamps (1.3uA minimum sensitivity for C664 Series Gas Ignition Systems). The minimum recommended fl...
  • Page 16 The fl ame also plays a very important role in this process. Because the fl ame is conductive, it allows the voltage to pass through its body like a bridge to the burner spreader ring. This {bridge} allows the built up spark voltage to bleed off of the igniter tip and move to ground more easily. The resultant ionized fl...
  • Page 17 Cracked Ceramic Spark Electrode Itʼs important to determine whether the spark electrode is faulty. Physical impacts and high heat can cause the ceramic post to fracture or crack. If this occurs the spark can shoot through the ceramic insulation and will normally go to ground on the burner head rather than through the fl ame /burner spreader ring.
  • Page 18 Takes too long to light None of these reasons for service are accurate indicators of a faulty igniter module. As with any Flame Rectifi cation Reignition system, the Dacor fl ame reignition system does have some critical issues that may prevent its correct function.
  • Page 19 OUTPUT VOLTAGE CHECK POINTS ON ERC/CLOCK CONTROL All Ranges And Wall Ovens When programming the oven into a cooking cycle, you fi rst select the desired mode on the touch membrane. Pressing this key sends a message to the ERC/Clock control, which in turn triggers 24 Volts DC to be sent to the main relay board through the connective harness.

At the main relay board take a voltage check from the BR (broil relay) to neutral should read 120 volts AC.
  • Page 33 ERC Quick Test The process requires two people. To access the program, one person should stand at the oven, while the other is located at the circuit breaker. The person at the circuit breaker turns off the breaker and then the person at the oven depresses and holds the cooktime keypad. The person at the circuit breaker then turns the breaker back on.
  • Page 34 THEORY OF OPERATION When keypad up/down button is pushed, contacts on the main PCB close between #12 and #13. Closing these contacts activates the triac for the sleeve motor which is connected to terminals L3 and N3 on the main PCB. The motor then raises the intake assembly until contact is made with the up stroke limit switch opening the circuit and reversing the electronic switch on the main PCB.
  • Page 35 If the above test does not show a closed circuit, perform the following. - Check for grease or any foreign material between the Touch Buttons and the contact board. Clean with an electronic contact cleaner as described above. - Repeat test above. - If the contacts are clear, replace the keypad assembly.
  • Page 36 that the Molex plug is securely attached to the main PCB. B. Unit will not raise or lower: 1. Check limit switches and the connecting wiring. 2. Check main PCB between L3 and N3 for 120 VAC when the UP/DOWN key is pressed. If voltage is not present check between terminals #12 and #13 on the PCB for continuity when the up/down key is depressed.
  • Page 37 2. Check for possible miswire of the exhaust motor. Quick Check – Main PCB: If the vent is not working at all: - Check the fuse on the main PCB - If the fuse is good check for continuity between the fuse and L3 (drive motor terminal) - If this circuit is open the PCB is bad and must be replaced.

The HIGH speed LED indicator will be on and the LOW and MEDIUM LED will be off. CLEAN FILTER BUTTON When the total number of hours that the fan has operated exceeds 10 hours, the FILTER CLEAN LED will be on indicating the fan has accumulated over 10 operating hours.
  • Page 39 Furthermore, the controller will learn the current status of the limit switches and the direction of the sleeve motor. However if both limit switches are closed during any stage of operation, the controller will only be able to operate the sleeve motor. FAILURE MODE, PCB PROGRAMMING The software for the vent is designed so that when the sleeve motor is travelling upwards, it will only look for the UPPER LIMIT switch.
