Both elements do not heat:
Checking the system with a Voltmeter, if the elements
do not heat up:
1.
Remove the back panel of the backguard to
expose the switch terminals.
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 4 and 2. If the meter reads zero the
switch is defective. If the meter reads line to
line voltage measure the voltage drop between
terminals 4A and 2. If the meter reads line to
line voltage the switch is good. Go to step 4.
4.
Raise the top and locate the two terminals on
the element with the wires from terminals 4
and 2 are connected. Measure the voltage drop
between these two terminals. If the meter reads
zero the wires between the switch and the
element 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.
Remove the back panel of the backguard to
expose the switch terminals.
2.
With the switch turned clockwise to the high
position measure the voltage drop between
terminals 4A and 2. If the meter reads zero
the switch is defective. If the meter reads line
to line voltage, go to step 3.
3.
Raise the top and locate the two terminals on
the element where the wires from terminals 4A
and 2 are connected. Measure the voltage drop
between these two terminals. If the meter reads
zero the wires between the switch and the
element are open. If the meter reads line to
line voltage the element 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.
Remove the back panel of the backguard to
expose the switch terminals.
2.
With the switch turned clockwise to the high
position measure the voltage drop between
terminals 4 and 2. If the meter reads zero
the switch is defective. If the meter reads line
to line voltage, go to step 3.
3.
Raise the top and locate the two terminals on
the element where the wires from terminals 4
and 2 are connected. Measure the voltage drop
between these two terminals. If the meter reads
zero the wires between the switch and the
element 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 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 4 and L2. If the meter reads zero the switch is
defective. If the meter reads line to line voltage (around
240VAC) the light or the wiring to the light is defective.
Indicator light glows full brilliance with all top ele-
ment switches off:
If indicator light glows full brilliance with all top element
switches off, one or more of switches are defective. Dis-
connect electrical power from the range, and remove the
back panel of the backguard. Disconnect the wire from
terminal 4 on the switches from all 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 dual
infinite switch by disconnecting the wires from all the
other 4 terminals but the switch you are testing.
