Diagnostics
IMPORTANT: Before powering microwave (MW) magnetron, be surethat a
load, such as a microwave-safe cup of water, is present in the microwave
oven cavity.
Unplug oven or disconnect power before performing thefollowing checks:
■ A potential cause of a control not functioning is corrosion on connections.
Observe connections andcheck for continuity with an ohmmeter.
■ 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.
IMPORTANT: Do not replace the control if there is no evidence of any failure.
