Dacor Range, Oven, Cooktop Error Code E2

On the Dacor DTF364SIWS, E2 indicates a refrigerator evaporator sensor error. The control board has detected that the evaporator thermistor circuit is open, shorted, or disconnected, meaning it cannot receive a valid temperature signal from the evaporator coil. This prevents the system from properly managing defrost cycles and compressor operation.

The E2 error itself does not represent an immediate safety hazard in the way that a gas or electrical fault would. However, because the evaporator sensor monitors temperature for defrost and cooling control, a failed sensor can lead to improper cooling, food spoilage, or excessive frost buildup if left unaddressed. The issue should be diagnosed and corrected promptly.

Resetting the appliance by disconnecting power for a few minutes may temporarily clear the E2 code, but the error will return if the underlying sensor circuit fault has not been corrected. A reset is useful for confirming whether the fault is intermittent, but it is not a fix. The sensor, wiring, and connectors should be inspected and tested to identify and resolve the root cause.

Some causes of the E2 error are accessible to a skilled DIYer. Checking and reseating the sensor connector requires no special tools and is a reasonable first step. Testing the thermistor with a multimeter is also straightforward if you are comfortable using one. However, replacing the control board or tracing a harness fault inside the cabinet may require disassembly that is better handled by a qualified technician.

Repair costs depend on which component has failed. A replacement evaporator thermistor is generally an inexpensive part, with the sensor itself typically ranging from around $15 to $60 depending on sourcing. A wiring harness repair or connector replacement adds minimal parts cost but may require labor time. A control board replacement is the most expensive scenario, with parts often ranging from $100 to $300 or more plus labor.
