TESTS FOR ELEMENTS




BROIL ELEMENT (4,000 Watts @ 240 VAC)


36_2
Measure when cool. (room temperature of 77° F / 25° C)

Normal resistance is 14 ohms ± 10%.

Replace if not within this spec.




BAKE ELEMENT (3,400 Watts @ 240 VAC)


36_3 Measure when cool. (room temperature of 77° F / 25° C)

Normal resistance is 17 ohms ± 10%.

Replace if not within this spec.


CONVECTION ELEMENT (700 Watts [each] at 240 VAC (2 installed)


36_4
Measure when cool. (room temperature of 77° F / 25° C)

Normal resistance is 80 ohms ± 10%.

Replace if not within this spec.




WARMING DRAWER ELEMENT (600 Watts @ 240 VAC)


37_1
Measure when cool. (room temperature of 77° F / 25° C)

Normal resistance is 95 ohms ± 10%.

Replace if not within this spec.




RIGHT REAR ELEMENT (single) (1,200 Watts @ 240 VAC)


37_2
Disconnect the wires from the cooktop element.

Test between the element terminal and terminal 1A.

Normal resistance is 46 ohms ± 10%.
37_3
Test between limiter terminals 1A and 2A.

Normal resistance is 0 ohms. (Continuity)
37_4
Test between limiter terminals 1B and 2B.

Below 150° F = infinite resistance (open)

Above 150° F = continuity (0 ohms)

Replace the element if any test shows the element to be out of spec.




BRIDGE CIRCUIT ELEMENTS

LEFT FRONT 7" (1,200 WATTS @ 240 VAC)

LEFT REAR 7" (1,200 WATTS @ 240 VAC)

BRODGE ELEMENT (800 WATTS @ 240 VAC)


38_1
Disconnect the wires from the cooktop element.

Test between terminals E1 and E2. Normal resistance is 33 ohms ± 10%.







Test between terminals E3 and E4. Normal resistance is 70 ohms ± 10%.









Test between terminals E5 and E6. Normal resistance is 31 ohms ± 10%.



Replace the element if any test shows the element to be out of spec.


38_2
Test between terminals 1A and 2A on both front and rear elements.

Normal resistance is 0 ohms (continuity).


38_3
Test between limiter terminals 1B and 2B on both front and rear elements.

Below 150° F = infinite resistance (open)

Above 150° F = continuity (0 ohms)

Replace the element if any test shows the element to be out of spec.




CENTER REAR ELEMENT (WARMING ZONE) (100 WATTS @ 240 VAC)


39_1
Disconnect the wires from the cooktop element.

Test between the element terminal and terminal 1A.
39_2
Test between the limiter terminals 1A and 2A.

Normal resistance is less than 0.5 ohms.

Replace the element if any test shows the element to be out of spec.


RIGHT FRONT ELEMENT (TRIPLE SURFACE UNIT)




39_3 Test between terminals 1A and E3.
Normal resistance is 70.5 ohms ± 10%
(OUTER 800 watts @ 240 VAC)

Test between terminals 1A and E2.
Normal resistance is 50.0 ohms ± 10%.
(MIDDLE 1,100 watts @ 240 VAC)

Test between terminals 1A and E1.
Normal resistance is 49.5 ohms ± 10%.
(INNER 1,100 watts @ 240 VAC)
39_4
Test between limiter terminals 1A and 2A.

Normal resistance is 0 ohms. (continuity)
39_5
Test between limiter terminals 1B and 2B.

Below 150° F = infinite resistance (open)
Above 150° F = continuity (0 ohms)

Replace the element if any test shows the element to be out of spec.
