Freezer compartment temperature alarm: FZ air

From Service Manual 450696, p.28:

1.For display models, press RESET ALARM key twice to exit alarm. For standard models, operate freezer knob to switch appliance off (OFF position) and on again.

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.
