GENERAL SAFETY FIRST Your safety and the safety of others is very important. We have provided many important safety messages in this Job Aid and on the appliance. Always read and obey all safety messages. This is the safety alert symbol. This symbol alerts you to hazards that can kill or hurt you and others.
ELECTROSTATIC DISCHARGE (ESD) SENSITIVE ELECTRONICS ESD problems are present everywhere. ESD may damage or weaken the electronic control assembly. The new control assembly may ap- pear to work well after repair is finished, but failure may occur at a later date due to ESD Electrical Shock Hazard stress.
