Dacor Range, Oven, Cooktop Error Code E0

On the Dacor DTF364SIWS, E0 specifically refers to a freezer air sensor error. The control board has detected that the freezer temperature thermistor circuit is open, shorted, or disconnected. This prevents the appliance from accurately monitoring freezer temperature. The fault must be diagnosed and corrected before normal operation can resume.

Continuing to use the appliance with an active E0 error is not recommended. Because the freezer air sensor is not functioning correctly, the refrigerator cannot reliably maintain safe freezer temperatures. Food safety may be compromised, and running the unit without accurate temperature feedback can also cause the compressor to operate improperly over time.

Repair costs vary depending on the root cause. A replacement freezer air thermistor typically costs between $20 and $60 for the part. If a control board replacement is required, parts alone can range from $150 to $400 or more. Adding professional labor, total repair costs can range from $100 to $600 depending on what components need to be replaced and local service rates.

A knowledgeable DIYer can perform basic checks such as inspecting the sensor connector for looseness and looking for obvious wiring damage. Testing the thermistor with a multimeter to verify resistance is also within reach for those comfortable with basic electrical diagnosis. However, replacing the sensor or control board involves working with refrigerant-adjacent components and disassembly that many homeowners prefer to leave to a qualified technician.

A power reset may temporarily clear the E0 code, but if the underlying sensor fault is still present, the error will return. A reset does not repair a failed thermistor, damaged wiring, or a disconnected harness. The root cause must be identified and corrected to permanently resolve the fault.
