What E8 means on a Dacor range oven cooktop

The E8 error code on the Dacor DTF364SIWS indicates an icemaker air sensor fault. The air sensor in the icemaker circuit is responsible for monitoring the ambient or compartment air temperature to regulate ice production cycles. When the control detects that this sensor circuit is open, shorted, or physically disconnected, it triggers the E8 code and may suspend normal icemaker operation to prevent damage or incorrect cycling.

The most common root causes align directly with the three conditions flagged by the diagnostic: an open circuit (indicating a broken wire or failed sensor element), a short circuit (where the sensor wiring has contacted a grounded surface or two conductors have bridged), or a complete disconnection of the sensor harness. In practice, the sensor itself is a thermistor-type component whose resistance changes predictably with temperature. If the control reads resistance values outside the expected range, it interprets this as a fault condition.

Diagnosis should begin with a visual inspection of the sensor and its wiring harness for any obvious damage, corrosion, or disconnected connectors. Following the visual check, resistance testing of the sensor across its terminals will confirm whether the component has failed open or shorted internally. The wiring between the sensor and the control board should also be checked for continuity and insulation integrity. If the harness and connectors test good, the sensor itself is the likely replacement candidate.

Common causes of E8

  1. 01

    Disconnected sensor harness connector

    Wiring / connection

    The wiring connector to the icemaker air sensor may have come loose, especially after any recent service or movement of the unit. Check the connector at both the sensor and the control board ends for a secure fit.

  2. 02

    Failed icemaker air sensor (open circuit)

    Part replacement

    The thermistor element inside the sensor can fail open, meaning it no longer completes the circuit. This will read as infinite or extremely high resistance when tested with a multimeter.

  3. 03

    Shorted sensor or wiring

    Part replacement

    A short can occur if the sensor wiring insulation has worn through and contacted a metal surface, or if the sensor element itself has internally shorted. This typically reads as near-zero resistance across the sensor terminals.

  4. 04

    Damaged wiring harness

    Part replacement

    The wire harness running from the icemaker air sensor to the control board can be pinched, cut, or corroded, breaking continuity in the circuit. Inspect the full length of the harness for visible damage.

  5. 05

    Control board fault

    Part replacement

    In rare cases, the control board may misread the sensor circuit due to a fault on the board itself. This should only be considered after the sensor and wiring have been confirmed good through testing.

Frequently asked questions about E8

What does E8 mean on a Dacor range, oven, cooktop?
On the Dacor DTF364SIWS, the E8 code specifically indicates an icemaker air sensor error. The control has detected that the sensor circuit is open, shorted, or disconnected. This fault will typically interrupt normal icemaker operation until the underlying issue is corrected.
Can I fix the E8 error on my Dacor appliance myself?
A knowledgeable DIYer can perform the initial diagnostic steps, including checking for a disconnected harness connector and visually inspecting the wiring for damage. Testing the sensor with a multimeter to check for open or shorted resistance is also within reach for someone comfortable with basic electrical testing. Replacing the sensor is generally straightforward once the faulty component is confirmed. However, if the control board is suspected, professional service is advisable.
Is the E8 error on a Dacor appliance a safety concern?
The E8 fault is related to the icemaker air sensor circuit and does not indicate a safety hazard such as a gas leak or fire risk. It is primarily a functional issue that affects ice production. You can continue using other functions of the appliance while this code is present, but the icemaker may not operate correctly.
How much does it cost to repair an E8 error on a Dacor appliance?
If only the icemaker air sensor needs replacement, parts costs typically range from around $20 to $80 depending on the component. Professional diagnostic and labor fees can add $100 to $250 or more depending on your location and service provider. If the control board is the cause, repair costs would be significantly higher.
Will resetting the Dacor appliance clear the E8 error code?
A power reset by unplugging the unit or cycling the breaker may temporarily clear the E8 code, but it will return if the underlying sensor fault has not been repaired. The code is generated because the control is actively detecting an abnormal condition in the sensor circuit. A permanent fix requires diagnosing and correcting the open, shorted, or disconnected sensor or wiring.
