CAUTION
1. Parts identified by the A\ symbol on the schematic diagram and the parts list are
Criticalfor safety.
Use only replacement parts that have critical characteristics recommended by the
manufacturer.
2. Make leakage-current or resistance measurements to determine that exposed parts
are acceptably insulated from the supply circuit before returning the appliance to the
customer.
