IMPORTANT: Electrostatic Discharge (ESD) Sensitive Electronics
ESD problems are present everywhere. ESD may damage or weaken the electronic control assembly. The new control
assembly may appear to work well after repair is finished, but failure may occur at a later date due to ESD stress.
■ Use an antistatic wrist strap. Connect wrist strap to green ground connection point or unpainted metal in the
appliance
-OR-
Touch your finger repeatedly to a green ground connection point or unpainted metal in the appliance.
■ Before removing the part from its package, touch the antistatic bag to a green ground connection point or
unpainted metal in the appliance.
■ Avoid touching electronic parts or terminal contacts; handle electronic control assembly by edges only.
■ When repackaging failed electronic control assembly in antistatic bag, observe above instructions.

Diagnostics
Unplug oven or disconnect power before performing the following checks:
■ A potential cause of a control not functioning is corrosion on connections.
Observe connections andcheck for continuity with an ohmmeter.
■ All tests/checks should be made with a VOM or DVM having a sensitivity
of 20,000 Ω per volt DC or greater.
■ Check all connections before replacing components, looking for broken
or loose wires, failed terminals, or wires not pressed into connectors far
enough. Damaged harness must be entirely replaced. Do not rework a
harness.
■ Resistance checks must be made with power cord unplugged from outlet
and with wiring harness or connectors disconnected.
■ If the oven does not heat, there may be a problem with connections to
the power supply. Check the connection to L2.
