Relay faulty

The fan is controlled by relay #3

To test refer to 3.4.6

Check red flag on relay top to see if relay is energised. If no flag present check voltage (24Vdc) to control relay coil. If voltage present replace relay.

If relay is operating check continuity through relay contacts. Replace if no continuity through contacts.

Relay #3

Fan motor timer faulty

With oven switched on, and door closed, ensure that the cams on the motor timer are rotating.

Motor Cams (Rotate one revolution every three minutes)

Figure 5.3.2c

If cams are rotating, then isolate the power supply from the oven. Remove the bottom wire from the left hand switch terminals. Rotate the cams manually whilst testing for continuity through the left hand switch. Check that the continuity cycles as the cams are rotated. Re-secure the left hand wire, and then repeat test for right hand switch.

When operating, 50Hz models should cycle the power for approximately 80 seconds through each switch, with a 10 second delay between each cycle.

On 60Hz models the power should cycle for approximately 65 seconds through each switch, with an 8 second delay between each cycle.

If there is no continuity, or the continuity does not cycle correctly then timer is faulty - replace.

Fan motor capacitor faulty

Ensure that oven is isolated from the power supply. Disconnect the two capacitor wires. Briefly short across the capacitor terminals, to ensure that it is fully discharged.

Using a multimeter, measure the resistance across capacitor terminals.

The resistance should start low and quickly increase to infinity within 5-10 seconds. If the resistance does not increase at all, then the capacitor is shorted - replace. If the capacitor is infinite resistance straight away then it is opencircuit - replace. If the resistance never goes very high then the capacitor is leaky - replace.

Electronic control faulty

If no voltage is present at relay coil and controller is calling for heating on display replace controller.

Heating contactor faulty

With a program selected, check that the heating contactor coil has voltage across the coil, terminals A1 and A2. If not check element contactor control relay (#2) and wiring.

If voltage is correct, check that contactor pulls in and closes the contacts when power to contactor coil is on. Correct operation will make an audible noise when closing contacts and on the front face of the contactor the contact mechanism will visibly pull in. If not, contactor is faulty—replace.

If contactor operates correctly, check for continuity through the poles of the contactor when closed. If no continuity through connected poles then contacts are blown and contactor requires replacing.

Figure 5.3.3b

For checking elements where temperature overrun is occurring, check that contactor releases (opens) when temperature control switches OFF. If not, contacts of the contactor have welded shut and elements will be ON and heating will be continuous. Contactor is faulty— replace.

Element faulty (blown)

With the controller on and calling for heat check voltage across element terminals at RH side of oven. If the voltage is correct then check the current draw of element. If there is no current draw then element is faulty—replace.

If there is no voltage then check voltage is being supplied to each element coil from the heating contactor. If no voltage to elements, check contactor operation and wiring.

Correct element current draw: Inner Coil 9.0A ± 2.5% Outer Coil 11.9A ± 2.5%

Correct element resistance: Inner Coil 26.8 ohms ± 5.0% Outer Coil 20.2 ohms ± 5.0%

Humidity probe faulty

To verify reading refer to 3.4.6

Switch the proofer on. Check that the humidity control cycles on / off, and using a suitable probe measure the temperature of the water in the trough. The water temperature should be 50° C/120°F ± 10%. If the temperature continues to rise above this then the humidity temperature probe is faulty - replace.

5.4.5 Auto-fill not filling or

overflowing

Water level float switch faulty

To verify reading refer to 3.4.6

To check correct operation of float switch remove the float switch wire connections from terminal 8 and terminal 5 on relay. With full water tank (float switch in raised position) float switch should be closed circuit. With empty water tank (float switch in lower position) float switch should be open circuit. If not, float switch is faulty—replace.

Solenoid relay faulty

E32SUBC auto-fill models are fitted with a 2 pole change over relay, with its coil controlled by the float switch located in the water trough / tank. When the water level is below the full position the coil is not energised, allowing the relay to supply power to the water solenoid through terminals 5 and 1

Water solenoid faulty

Empty water tank so float switch is in lowest position. With power ON check voltage across water solenoid coil terminals. If voltage is correct (refer electrical rating plate) but solenoid is not operating, disconnect electrical supply and remove wire connections from solenoid. Check solenoid coil windings resistance.

Correct coil resistance: 208 - 240 volt models 3650 Ω

NOTE:

coil is faulty– replace.

If coil is correct, rewire and listen for audible solenoid click when power is supplied. If solenoid can be heard functioning and water supply is turned on but no water is entering tank, remove water solenoid and fittings and check for blockages.

If open circuit/high resistance, then the
