Display shows E3 and the refrigerator may run continuously or not defrost properly.

Safety: Disconnect power before removing freezer panels or working near the evaporator.

Steps:

• Empty the freezer: Remove shelves, bins, and ice bucket to access the rear evaporator cover.
• Remove evaporator cover: Take out the screws and gently pull the cover forward. Be careful not to damage the foam insulation.
• Locate the evaporator thermistor: It is usually clipped to the evaporator tubing or mounted on the evaporator bracket with a small plastic clip.
• Inspect placement: Ensure the thermistor is firmly attached to the coil or bracket and not hanging loose. A loose sensor can cause incorrect readings.
• Check wiring: Look for ice damage, chafed wires, or corroded connectors. If the harness is damaged, it may need to be repaired or replaced.
• Replace sensor if faulty: If the thermistor is cracked, swollen, or tests open/short with a multimeter, replace it with a Crosley-compatible evaporator thermistor.
• Reassemble: Reinstall the evaporator cover, ensuring no wires are pinched. Restore power and monitor for proper defrost operation and disappearance of the E3 code.
