Revision 6/F3501
© Moffat Ltd, August 2006 E25 Convection Oven -21-
Indicator faulty
With thermostat in broil position, check the
voltage across the indicator terminals. If the
voltage is correct then indicator is faulty—
replace.
If there is no voltage then check wiring.
6.1.13 BROIL INDICATOR NOT WORKING
(E25B ONLY)
Heating relay faulty
With the oven switched off, disconnect the
wires from terminals 7 and 4 of the heating
relay. Check for continuity through these
terminals. If there is continuity then the relay
is faulty—replace.
6.1.14 OVEN OVERHEATS IN BROIL MODE
(E25B ONLY)
Power switch faulty
Check if power switch latches. If the switch
does not latch, then the switch is faulty—
replace.
With switch unlatched and door open, check
voltage across terminal 2 to terminal 3 or 4. If
there is voltage then the switch is faulty—
replace.
Alternatively, perform a continuity test across
terminals 1 and 2. This should show an open
circuit when the switch is unlatched.
NOTE: When power switch is unlatched it
should not be illuminated if operating
correctly.
Broil relay faulty (E25B only)
With power switch off, check for voltage at
terminal 4 of broil relay. If there is voltage
then the relay is faulty—replace.
Heating relay faulty (E25B only)
With the oven switched off, disconnect the
wires from terminals 9 and 6 of the heating
relay. Check for continuity through these
terminals. If there is continuity then the relay
is faulty—replace.
6.1.15 POWER SWITCH DOES NOT TURN
UNIT OFF.
