Element Does Not Cycle - Electrolux 30" Service Manual

NOTE: Always inspect the terminal block for burnt spots
that can cause a poor connection.
5. Raise the top and locate the two terminals on the
element that the wires from H1 and H2 are on.
Measure the voltage drop between the two
terminals. If the meter reads zero the wires be
tween the switch and the element are open. If the
meter reads line to line voltage the element is de-
fective.

Element does not cycle:

If the element does not cycle when the switch is set in a
position other than high, the switch is defective.
Indicator light does not glow:
If indicator light does not glow when the switch is turned
on, remove the back panel of the backguard, turn the
switch on, and measure the voltage drop between termi-
nals P and L2. If the meter reads zero the switch is
defective. If the meter reads line to line voltage (around
240 VAC) the light or the wiring to the light is defective.
Indicator light glows full brilliance with all top
element switches off:
If indicator light glows full brilliance with all top element
switches off, one or more of the switches are defective.
Disconnect electrical power from the range, and remove
the back panel of the backguard. Disconnect the wire
from the P terminal on all switches but one switch. Re-
connect power. If the indicator light glows with the switch
in the off position, the switch is defective. If the indicator
light does not glow, the switch is good. Check each
switch by disconnecting the wires from all the other P
terminals except the switch you are testing.
Dual infinite switch:
The dual infinite switch is used to control the expand-
able and bridge elements on electric smooth top ranges.
The dual infinite switch provides an infinite choice of heat
settings for cooking, and two selections of element sizes.
Controls are safety type and must be pushed in before

turning. All surface controls are marked on the control
panel for their respective heating element. When the knob
is turned clockwise, less than 180 degrees, contacts
P2 to 4, P2 to 4A, and P1 to 2 close providing power to
both elements. When the knob is turned counterclock-
wise, less than 180 degrees, contacts P2 to 4 and P1 to
2 close providing power to the inner element. During
actual surface element operation, if the control is set to
the high position contacts P1-2 are lock closed provid-
ing continuous power to the element. In all other set-
tings contacts P1 to 2 will cycle to maintain the correct
heat setting. Contact 4 to L2 provides power to the
surface element indicator light.

Troubleshooting:
There are six ways a surface control system with a dual
infinite switch can fail.
1. Both elements do not heat.
2. The outer element does not heat.
3. The inner element does not heat.
4. The switch does not cycle the element off and on
when set to a position other than high.
5. The element operates correctly, but the indicator light
does not glow.
6. Indicator light glows with all the infinite switches in
the off position.
NOTE: If the indicator light glows very dimly with all
the switches in the off position, the problem is
caused by a capacitive feed over in the wiring
and can be corrected by connecting a
100,000 Ohm 1/4 watt resistor in parallel with
the light.
