Kenmore 808353 - Manual (Page 70)

To determine if the timer is defective, attach the voltmeter lead to point #3 shown in Figure 71 leaving the other
voltmeter lead attached to the while or common terminal, 120 Volts AC present at this point indicates that the timer
is not defective. No vottage at this point would indicate a defective timer,
NOTE:
Always be certain the timer is set to
the portion of the cycle in question when making voltage checks Some segments of the cycle have a short duration and
can be missed.
Continuity Check
An alternate method of checking the timer is to disconnect the machine from the power source and make a continuity
check. This continuity check of timer switches may be made by disconnecting the lead from the timer terminals in question,
and connecting the leads from your ohmmeter across the timer switch.
For example, if the motor wiii not start in the wash cycle, disconnect power from the machine and remove the wire from
the timer’s BU-BK terminal (Figure 71). Connect one ohmmeter lead to BU-BK and the other to BU-Y With the timer
knob rotated to the wash phase of the cycle, the ohmmeter should register continuity or no resistance, If the timer switch
is defective the meter will indicate an open circuit or infinite resistance
All timer switches may be checked in the same manner by referring to the Ester line chart and wiring diagram, and
connectng the ohmmeter leads to the correct combination of terminals. NOTE; Correct interpretation of the meter reading
is important A continuity check of a switch should indicate no resistance, A resistance reading of other than lero or
infinity could be the result of damaged or burnt contacts which would reduce power to the component Do not make a
continuity check with an ohmmeter when the machine is connected to a iive eiectricai circuit. Damage to the meter will
result.
Other eiectricai components in the dishwasher may be checked in the same manner. Some resistance will be noted when
checking motors, coils and heating elements.
