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.
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.
IMPORTANT: Do not replace the control if there is no evidence of any failure.
