SWITCH-FAIL Control switch or touch panel failure on a Dacor range hood (DHD30, DHD36, DHW36, DHI482). One or more fan speed or light controls do not respond to user input, or respond erratically, making reliable hood operation impossible. Range Hood Medium E2 Freezer compartment temperature sensor failure on Dacor DRF36/DRF42 French Door refrigerators. The freezer thermistor circuit is open or shorted, causing the control board to lose freezer temperature data and disrupting defrost and cooling cycles. Refrigerator High E3 Defrost heater or defrost sensor circuit fault on Dacor DRF36/DRF42 French Door and DRZ36 built-in refrigerators. The defrost system has failed to complete a cycle within the expected time window, indicating a heater, thermal fuse, or defrost thermistor failure. Refrigerator Medium NO-POWER Complete loss of power to a Dacor range hood (DHD30, DHD36, DHW36, DHI482). The hood does not respond to any control inputs — no fan, no lights, no display indicators — indicating a loss of electrical supply or a failed control board. Range Hood Medium VENT-BLOCK Blocked or restricted ductwork on a Dacor range hood reducing airflow to an ineffective level. The hood fan is running but cooking vapors, smoke, and odors are not being evacuated, indicating a duct obstruction, collapsed duct, or closed exterior damper. Range Hood Medium

Filter: Sort:
Code Appliance Meaning Severity
E1 Column Refrigeration Refrigerator compartment temperature sensor failure on Dacor DRR24 and DRR30 column refrigerator models. The NTC thermistor monitoring the cabinet interior has developed an open or short circuit, preventing the control board from accurately regulating column refrigerator temperature. High View details → E3 Column Refrigeration Defrost system fault on Dacor DRR24 and DRR30 column refrigerators. The column refrigerator has failed to complete an automatic defrost cycle, causing frost to accumulate on its dedicated evaporator and reducing cooling capacity within the column cabinet. Medium View details → E4 Column Refrigeration Evaporator fan motor failure on Dacor DRR24 and DRR30 column refrigerators. The fan responsible for circulating cold air within the column refrigerator cabinet has stopped or is running outside acceptable speed limits, causing the column cabinet to warm even while the compressor operates. High View details → HI Column Refrigeration High temperature warning on Dacor DRR24 and DRR30 column refrigerators. The column cabinet has exceeded its upper temperature threshold, alerting the user that food safety may be at risk. The cause may range from a simple door issue to an underlying refrigeration fault specific to the DRR-series. Medium View details → PF Column Refrigeration Power failure notification on Dacor DRR24 and DRR30 column refrigerators. The column unit detected an interruption in electrical supply and is alerting the user to verify food safety following the power restoration. The column refrigerator resumes cooling automatically. Low View details → E1 Cooktop Incompatible or absent cookware detected on a Dacor DTI-series induction cooktop. The zone sensor cannot detect a ferromagnetic vessel of sufficient size, and the zone will not energize to prevent energy waste and surface overheating. Low View details → E3 Cooktop Input voltage out of range on a Dacor DTI-series induction cooktop. The unit has detected that the supply voltage is significantly above or below the 240V nominal required for safe operation, and has suspended all cooking functions. Medium View details → F1 Cooktop Internal control board failure detected on Dacor induction cooktop (DTI30/DTI36). The main PCB has encountered a critical self-diagnostic fault and cannot safely regulate induction coil power output. High View details → F2 Cooktop Temperature sensor (thermistor) fault on a Dacor induction cooktop. The control board cannot read a valid temperature signal from one or more zone sensors, triggering a safety shutdown to prevent overheating. High View details → F3 Cooktop Cooling fan failure detected on a Dacor DTI-series induction cooktop. The internal fan that protects the power electronics from overheating has stopped or slowed below the minimum speed threshold, triggering a protective shutdown. High View details →
