Both Elements Do Not Heat - Electrolux 30" Service Manual

Both elements do not heat:

Checking the system with a Voltmeter, if the elements
do not heat:
1. Disconnect power, roll the control panel forward to
expose the switch terminals and reconnect power.
2. With a Voltmeter set for AC and a scale higher than
240 Volts measure the voltage drop between
terminals P1 and P2. If the meter reads zero the
wiring between the main terminal block on the range
and the switch is open. If the meter reads line to
line voltage (around 240 VAC) go to step 3.
3. With the switch turned clockwise to the HI position,
measure the voltage drop between terminals 2 and
4. If the meter reads zero the switch is defective. If
the meter reads line to line voltage measure the
voltage drop between terminals 2 and 4A. If the
meter reads line to line voltage the switch is good.
Go to step 4.
4. Raise the main top and locate the two terminals on
the element with the wires from terminals 2 and 4
are connected. Measure the voltage drop between
these two terminals. If the meter reads zero the
wires between the switch and the elements are open.
If the meter reads line to line voltage the element is
defective.
Outer element doesn't heat, but inner element does:
Checking the system with a Voltmeter, if the outer ele-
ment does not heat, but the inner element does:
1. Disconnect power, roll the control panel forward to
expose the switch terminals and reconnect power.
2. With the switch turned clockwise to the HI position,
measure the voltage drop between terminals 2 and
4A. If the meter reads zero the switch is defective.
If the meter reads line to line voltage the switch is
good. Go to step 3.
3. Raise the main top and locate the two terminals on
the element where the wires from terminals 2 and
4A are connected. Measure the voltage drop be-
tween these two terminals. If the meter reads zero
the wires between the switch and the elements are
open. If the meter reads line to line voltage the ele-
ment is defective.
Inner element doesn't heat, but outer element does:
Checking the system with a Voltmeter, if the inner ele-
ment does not heat, but the outer element does:
1. Disconnect power, roll the control panel forward to
expose the switch terminals and reconnect power.
2. With the switch turned clockwise to the HI position,
measure the voltage drop between terminals 2 and
4. If the meter reads zero the switch is defective.
If the meter reads line to line voltage the switch is
good. Go to step 3.
3. Raise the main top and locate the two terminals on
the element where the wires from terminals 2 and 4
are connected. Measure the voltage drop between
these two terminals. If the meter reads zero the
wires between the switch and the elements are open.
If the meter reads line to line voltage the element is
defective.
Elements do not cycle:
If the elements do not cycle when the switch is set in a
position other than high the switch is defective.
Indicator light does not glow:
If the indicator light does not glow when the switch is
turned on, disconnect power, roll the control panel for-
ward, and reconnect power. Turn the switch on, and
measure the voltage drop between terminal 4 and L2. If
the meter reads zero the switch is defective. If the meter
reads line to line voltage the light or the wiring to the light
is defective.
Indicator light glows full brilliance with all top ele-
ment switches off:
If the indicator light glows full brilliance with all the top
elements switches off, one or more of switches are de-
fective. Disconnect electrical power from the range, roll
the control panel forward. Disconnect the wire from ter-
minal 4 on the switches from all but one switch. Recon-
nect 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
infinite switch by disconnecting the wires from all the
other 4 terminals except the switch you are testing.
