OVEN SYSTEMS Figure 28: Survey Meter Placement 5. Close the oven door and press the Enter key. The microwave system will turn on. 6. Position the microwave survey meter as shown in Figure 28, above. 7. Measure microwave emission around the door, moving the meter sensor at 0.5 inches/second.
Microwave System The i5 oven employs two independent microwave systems (left and right). In the case of an over- current situation relative to the left system, the F3 fuse will blow. In the case of an over-current situation relative to the right system, the F4 fuse will blow.
Page 46
OVEN SYSTEMS NOTE: The terminals with the orange dot or the orange wire always go to Terminal 3 on US models. To verify correct wiring (International), measure the voltage between the taps on FT1 and FT2. The voltage must be 220 VAC (Latin America), 200 VAC (Japan), or 230 VAC (International).

High Voltage Transformers NGC-3062-1 NGC-3062-2 NGC-3062-3 Filament Transformers NGC-3061-1 NGC-3061-2 NGC-3061-3 High Voltage and Filament Transformer Resistance Table When the high-voltage winding starts to go toward negative, the high-voltage diode becomes non- conducting with the charged high-voltage capacitor in series with the high-voltage winding. When the transformer gets to its negative peak of -2400 VPK, the voltage applied to the filament is negative 4500 volts.
OVEN SYSTEMS Magnetrons Figure 30. Magnetrons supply the RF energy at 2.45 GHz and begin to oscillate when they are supplied with approximately 4.1 kVDC at approximately .350 mA. During operation each magnetron will output a nominal 1 kW of power. If replacement is required, conduct a microwave leakage test (page 27) after installation of new magnetron.
Control System This section contains information about the following components: - Control board - Display - Electrical compartment cooling fans - Electrical compartment cooling fan thermostat - Electrical compartment thermocouple - EMI Filter - Fuses - High-limit thermostat - Keypad - Magnetron cooling fans - Magnetron thermostats - Power Supply...
OVEN SYSTEMS High Limit Thermostat The high limit thermostat is a 250 VAC, 3-pole, manual-reset thermostat with a trip point of 572 º F (300 º C). The thermostat interrupts power to the main convection heater in the event of an abnormal condition.
Relay - K7 Magnetron Cooling Fan The K7 relay is a 240 VAC, 30 amp, double-pole, double-throw, 24 VDC relay coil. It switches power to the magnetron cooling fans when the magnetron filaments are actuated. Power is switched off after 4 minutes, 15 seconds.
Vent Catalyst In addition to the main catalytic converter, the i5 oven contains an additional catalyst in the vent tube path. This catalyst further assists in the breakdown of grease and particulate matter before the excess air enters the atmosphere.
Overview of Troubleshooting This section contains information on the following: - Fault code descriptions - Fault code troubleshooting - Non-fault code troubleshooting For information on accessing TEST MODE 15. For information and illustrations on replacing components, see the appendix. Fault Code Descriptions For instructions on viewing the fault counter, see page 13.
