Electrical Shock Hazard IMPORTANT

Disconnect power before servicing. Electrostatic Discharge (ESD) Replace all parts and panels before Sensitive Electronics operating. Failure to do so can result in death or ESD problems are present everywhere. ESD may electrical shock. damage or weaken the electronic control assem- bly. The new control assembly may appear to work DIAGNOSTICS well after repair is finished, but failure may occur at a later date due to ESD stress. Before servicing, perform the following checks: Use an anti-static wrist strap. Connect wrist The most common cause for control failure is strap to green ground connection point corrosion on connectors. Therefore, disconnecting or unpainted metal in the appliance and reconnecting wires will be necessary -OR- throughout test procedures. Touch your finger repeatedly to a green ground connection point or unpainted Check all connections before replacing metal in the appliance. components, looking for broken or loose wires, failed terminals, or wires not pressed Before removing the part from its package, into connectors far enough. touch the anti-static bag to a green ground connection point or unpainted metal in the All tests/checks should be made with a VOM or appliance. DVM having a sensitivity of 20,000 ohms per volt DC or greater. Avoid touching electronic parts or terminal contacts; handle electronic control assembly Resistance checks must be made with power cord by edges only. unplugged from outlet, and with wiring harness or connectors disconnected. When repackaging failed electronic control assembly in anti-static bag, observe above Fahrenheit (° F) to Celsius (° C) instructions. Conversion Programming the Cavity Size The default is Fahrenheit (° F). When replacing the electronic control, be sure to 1. Press the BROIL pad for 5 seconds.
