3.3 EXPLANATION OF CONTROL

SYSTEM

The E25 and E25B Turbofan convection ovens feature multi-function operator controls for which a correct understanding of their operation is required before carrying out any service or fault repair work. The control device functions are explained as follows:

A power switch on the control panel isolates power to all the controls of the oven. With the power switch Off all functions of the oven are inoperable.

NOTE:

side of the heating element power relay on E25B models whenever the electrical supply is on.

With the power switch On (illuminated) power is directly supplied to the 60 minute bake timer, door microswitch, temperature control circuit, and the light switch. The light switch will turn the oven light on when the door is closed, but only whilst the light switch is held in.

The door microswitch on the E25 oven controls the oven light only. Accordingly the light will come on when the door is opened but the circulation fan and fan element will remain on. The door microswitch on the E25B oven however, controls the light, the circulation fan, and the fan element. Hence, opening the door on the E25B oven causes the circulation fan and fan element to switch off, as well as causing the oven light to come on. (The broil function incorporated into the E25B oven requires the fan to be inoperative when broiling with the door open).

The 60 minute timer is a mechanical timer and can therefore be operated with the oven’s power switch On or Off. However, only with the oven’s power switch On will the switch contacts of the 60 minute timer turn on the time-up buzzer and illuminate the time-up indicator on the control panel. The buzzer and time-up indicator provide indication that the time setting has run down to zero and at this point will remain On continuously until the 60 minute timer has been manually set back to the Off (vertical) position. The 60 minute timer does not control any other part of the oven’s operating system as this timer is independent of the temperature control and heating system.

The temperature control of these ovens is with

The supply voltage is fed to the input

a capillary type thermostat which can be set to a required cooking temperature. The E25B also features a Broil position to provide top browning or broiling in the oven.

The E25 has an element coiled around the circulation fan in the rear of the oven. Power to the element is provided directly from the thermostat. The control panel indicator light above the thermostat knob cycles on and off with the thermostat to indicate when the element is on and the oven is heating. In the ‘Off’ position, the element relies on the thermostatic control to prevent it switching on. Accordingly, if the oven temperature drops below approximately 20°C the thermostat and element may cycle on at this setting.

The E25B features a Broil element (located in the top of the oven) as well as the fan element. The thermostat switch has a separate switch assembled onto the front of the shaft assembly. This auxiliary switch, depending on the thermostat setting, selects between the fan or broil elements, via a Broil relay located at the rear of the oven. A changeover contact on the broil relay determines which element is provided with power. In series with the broil relay is a second relay which is controlled by the main thermostat switch. This is the heating relay. One pole of the heating relay switches power to the fan element, the other pole switches power to the broil element. When the thermostat cycles, both poles are switched open or closed at the same time. However, since only one pole is being fed power by the broil relay, only the selected element cycles on.

When the E25B thermostat is set to a cooking temperature, one set of auxiliary switch contacts remain open. This isolates power from the coil of the two pole broil relay. In this state the normally closed contacts of the first pole provide power directly from the phase connection on the terminal block to the fan element pole on the heating relay. (The normally closed contact on the second pole is unused with this thermostat setting). The second set of auxiliary switch contacts is closed to feed power from the door microswitch to the main thermostat switch. When the thermostat cycles on it in turn feeds power to the coil of the heating relay, causing the changeover poles to switch. This closes the normally open contacts and provides power to the fan element. When the thermostat cycles Off it isolates power to the heating relay coil. This causes the normally

Revision 7/F3501

-10-

open contacts to reset, thus switching the fan element off. The control panel indicator light above the thermostat knob cycles on and off with the thermostat to indicate when the elements are on and the oven is heating.

When the E25B thermostat is set to the Broil position the first set of auxiliary switch contacts close and the second set open. The closed contacts provide power to the coil on the Broil relay. The opened contacts isolate power from the door microswitch to the main thermostat switch. With the thermostat in this setting, power to the coil of the broil relay causes the changeover contacts on both poles to switch. The normally closed contacts of the first pole on the Broil relay open, isolating power to the fan element. The normally open contacts of this pole close providing power instead to the broil element (via the heating relay). Switching of the second pole of the Broil relay closes the normally open contacts, providing power directly to the main thermostat switch. (This alternate power supply to the thermostat allows the Broil element to continue to operate with the oven door open and fan off). When the thermostat cycles On it provides power to the coil of the heating relay. When the heating relay switches, the normally open contacts on both poles close. However, with the thermostat in this position, power is only being provided to the pole feeding the broil element so only the broil element cycles On. When the thermostat cycles Off it isolates power to the heating relay coil. This causes the normally open contacts to reset, thus switching the broil element off again. With the door closed the broil element will cycle On/Off thermostatically at 600°F as this is the thermostat setting in the Broil position. With the door open the broil element will remain on continuously and the circulation fan will be turned off. The main heating indicator will cycle on and off with the thermostat and broil element, whilst the broil indicator will remain illuminated as long as the thermostat is in the Broil setting.

The following Troubleshooting Guide (pg 13) should be used to identify any incorrect oven operation. On correct identification of the operating fault the Troubleshooting Guide will make reference to the corrective action required, or refer to the Fault Diagnosis section and/or Service section to assist in correction of the fault.

6.1 FAULT DIAGNOSIS

6.1.1 OVEN DOES NOT OPERATE / START

Incorrect electrical supply

Check that the voltage across phase and neutral (L1 and L2) terminals of terminal block is the voltage as stated on the unit’s electrical rating plate.

If incorrect, check electrical connection of supply wiring and / or check electrical supply.

Power switch faulty

Check if power switch latches. If the switch does not latch, then switch is faulty—replace.

With switch latched, check voltage across terminal one to terminal three or four. If there is no voltage, check for fault in wiring.

Check voltage across terminal two to terminal three or four. If there is no voltage, then switch is faulty—replace.

NOTE:

When power switch is latched, it

should illuminate if operating correctly.

Check the supply voltage across lamp housing terminals at rear of oven. If the voltage is correct, replace the bulb (if faulty). If the bulb is OK, check lamp housing. Replace if faulty.

If there is no voltage, check voltage across micro-switch terminals to neutral.

With the door closed there should be power to the com terminal and the n.o. terminal.

With the door open there should be power to the com terminal and the n.c. terminal.

If not, microswitch is faulty—replace.

Fan motor faulty

With door closed, check the supply voltage across motor terminals. If there is no voltage then check the electrical connections of supply wiring.

If voltage is correct then check the oven fan for free rotation. Remove any obstruction.

If fan is free to spin and the voltage supply is correct, then the motor is faulty—replace.

Microswitch out of adjustment - E25B only

Open oven door and manually depress door microswitch actuator at top right of oven. If this activates the fan, then the microswitch actuator arm inside control cavity requires adjustment.

Microswitch faulty - E25B only

Check voltage across microswitch terminals to neutral.
