How to Fix / Troubleshooting

Safety first: Disconnect power and allow the unit to cool before accessing the heater or duct area.

Locate NTC sensor: On Insignia combos, the NTC is typically mounted on the heater housing or exhaust duct. Remove the rear or side panel to access it.
Inspect wiring: Check the NTC connector and wiring harness for secure fit and damage. Reseat the connector.
Measure resistance: With the sensor disconnected, use a multimeter to measure its resistance at room temperature. Compare to the service manual specification. An open circuit or zero ohms indicates a failed sensor.
Replace NTC: If readings are out of range, replace the NTC sensor with the correct Insignia part number. Ensure it is firmly attached to the duct or heater surface.
Test dry cycle: Reassemble panels, restore power, and run a timed dry cycle to confirm proper heating and that E10 does not reappear.

Washer-dryer combo displays E10 and will not heat during drying; cycle runs but clothes remain wet and cool.
