2LED Switch Replacement

The light-emitting diode (LED) switches on the control panel have a very low failure rate. In case a switch should ever be suspect, first test it per the description that follows. To replace the switch, refer to Figure 8.

1. Remove the wires from the suspected switch.

2. Set multimeter to ohms scale. Set ohms scale to R x 1, then zero the meter.

3. Connect multimeter leads to appropriate LED switch contacts (see Figure 8 for designation of switch contacts and meter lead placement).

4. Check contacts (push and release the switch button) for closed and open continuity.

5. If the contacts do not operate sharply or always remain closed or open, then replace the LED switch as outlined in the figure.
