Dacor Range, Oven, Cooktop Error Code E1

On the Dacor DTF364SIWS, the E1 code specifically indicates a freezer evaporator sensor error, meaning the control board has detected an open, shorted, or disconnected condition in the freezer temperature sensor circuit. Despite being listed under range, oven, and cooktop categories, this code applies to the refrigerator model. The appliance cannot reliably read freezer temperatures until the sensor circuit is repaired.

With the E1 code active, the refrigerator cannot accurately monitor freezer temperatures, which means defrost cycles and compressor control may not function correctly. Food safety could be at risk if freezer temperatures drift outside safe ranges without triggering proper responses. It is advisable to verify that the freezer is maintaining adequate temperatures with a separate thermometer and to address the fault as soon as possible.

Resetting the appliance by disconnecting power for a few minutes may temporarily clear the E1 code, but the fault will return if the underlying sensor circuit problem has not been corrected. A reset is useful for confirming whether the code is persistent or intermittent, but it does not repair an open circuit, shorted sensor, or broken wire. Proper diagnosis and repair of the sensor circuit are required for a lasting resolution.

A knowledgeable DIYer can check for a disconnected sensor connector and inspect visible wiring for obvious damage without specialized tools. Testing the thermistor resistance with a multimeter is also within reach for someone comfortable with basic electrical diagnostics. However, if the sensor or control board needs replacement, comfort with disassembling refrigerator panels and working around refrigerant lines is helpful, and some may prefer a qualified technician.

If the issue is simply a loose connector, there may be no parts cost at all, with only a service call fee to pay, typically in the range of $75 to $150. Replacing the evaporator thermistor is a relatively inexpensive repair, with parts generally ranging from $20 to $60 and labor adding $100 to $200 depending on your location. A control board replacement, if needed, is significantly more costly, with parts ranging from $150 to $400 or more.
