Display shows E2 and freezer temperature is too warm or too cold compared to the setpoint.

Safety: Unplug the refrigerator before working in the freezer compartment or at the control board.

Steps:

• Locate the freezer thermistor: On many Crosley top-freezer and side-by-side units, the freezer thermistor is mounted on the rear wall of the freezer, often behind a small plastic cover or clipped near the evaporator cover.
• Inspect wiring: Remove the cover and check the thermistor leads for damage from ice, food items, or shelf edges. Look for brittle or cracked insulation.
• Check connector: If the thermistor plugs into a small connector, unplug and replug it to ensure a solid connection.
• Test resistance (optional): With the unit unplugged, disconnect the thermistor and measure resistance. At freezer temperatures (~0°F / -18°C), NTC thermistors typically read higher resistance (e.g., 20k–30k ohms). A reading of 0 or infinite indicates a failed sensor.
• Replace if needed: Install a Crosley-compatible freezer thermistor, routing the harness exactly as the original to avoid contact with moving parts or sharp edges.
• Reassemble and test: Reinstall any covers, restore power, and monitor freezer temperature and error display over the next 24 hours.
