Display shows E7; ambient temperature readings may be incorrect, affecting cooling performance.

Safety first: Disconnect power before accessing any sensors behind panels or grilles.

• Locate ambient sensor: On many JennAir models, the ambient thermistor is located behind the toe grille or in the machine compartment, sensing room temperature.
• Inspect sensor and wiring: Check for broken wires, corrosion, or a sensor that has come loose from its mounting point.
• Test sensor: Remove the thermistor and measure resistance at room temperature. Compare to the expected NTC value (~2.7–3.5 kΩ at 77°F). Replace if open, shorted, or far out of range.
• Reinstall correctly: Mount the new sensor in the same location, away from hot components like the compressor or condenser.
• Control board: If E7 remains after sensor replacement and wiring checks, the main control board may be faulty and should be evaluated by a technician.
