1 | Use the "Manual Function Test" [as described on the electrical schematic sheet (6 918139)] to | |||||||
|
|
|
|
|
|
| ||
check components before opening the door to perform continuity testing or replacing parts. | ||||||||
| ||||||||
|
|
|
|
|
| |||
| To check continuity from ends of power leads to control board through door switches |
| ||||||
| (A white plastic latch must be inserted in the latch assembly for this test.) | |||||||
|
|
|
| |||||
2 | > With one ohm meter lead connected to the white (neutral) power lead, you should have continuity at | |||||||
stake lugs 10 & 11. | ||||||||
| ||||||||
| > With one ohm meter lead connected to the black (line) power lead, you should have continuity at | |||||||
| stake lugs 3 & 4, and pin # 8 on connector J5. | |||||||
3 | Perform the resistance checks on the component(s) in question at the locations shown on the chart. | |||||||
| * Select Models Only. | |||||||
** Nominal value for ohms of electrical resistance of component only. These values will vary slightly due to the additional resistance of the wire harness. Greater variation can occur if the component is still warm from being energized during testing.
*** A resistor in the control board wired in parallel will result in an approximate reading of 4.0 k ohms with connector J5 plugged in.
Wash Motor (3 - 4**)
Heater
(14.5 - 16.5**)
(High limit t'stat must
be closed)
Always remove power to the unit
before performing any resistance or
continuity checks.
