Cavity 2 meat probe sensor temperature too low

From Service Manual 972983, p.35:

1.Check with customer to determine if probe was used in frozen food. Check probe operation and resistance. Check for loose connections and/or pinched wires.

2.Measure control board supply voltage at the test points. Expected: 12 VDC and 5 VDC; a drop below 4.75 VDC on the logic rail points to a failed onboard regulator.

3.Inspect all connectors on the main control for corrosion, thermal stress, or backed-out pins. Reseat each connector with the power disconnected.
