C8 error on Electrolux dryer: what it indicates and how to act

What the C8 error on an Electrolux dryer indicates

The C8 error points to a fault in the temperature NTC probe or the circuit that carries its signal to the control board. It is not a cosmetic or generic warning: when the thermal reading opens, shorts, becomes unstable, or disappears, the dryer protects itself and stops the cycle because it cannot guarantee safe, controlled drying.

Why the NTC probe is decisive

The NTC (negative temperature coefficient thermistor) is the appliance’s internal thermometer: its resistance changes with temperature and that variation is the information the board uses to decide how much to heat and when to stop. When the probe or its signal path fails, the electronics lose a basic reference and the machine either interrupts the cycle or regulates heat erratically to avoid risk.

The probe and its circuit, piece by piece

• NTC sensor: can age, become contaminated, break internally or lose contact, producing open-circuit or out-of-range resistance readings.
• Connectors and wiring: a loose plug, corroded terminal, rubbed or broken conductor (especially near flex points) can create intermittent or impossible readings indistinguishable from a faulty sensor.
• Control board: rarely the first cause, but a board that misinterprets a correct signal can also produce C8. Start with the probe and wiring because they suffer most from heat and vibration.

How C8 typically shows up in daily use (symptoms)

• The code appears on the display shortly after starting a program or during operation.
• The dryer may stop immediately or run for a few minutes and then interrupt the cycle.
• Irregular drying: heat comes and goes, cycles take too long, or clothes come out unevenly dried with damper areas.
• Intermittent, erratic behavior across attempts—fits with a connection or wiring issue that behaves inconsistently.

Quick diagnostic summary

• Code: C8
• Description: Issue with the temperature NTC probe or its circuit
• Common causes: open circuit, short circuit, loose connector, damaged cable, faulty sensor, or rarely a control board fault
• What it implies: The dryer cannot measure heat properly and protects the system by interrupting or limiting cycles
• Priority check: Inspect probe, connectors, and wiring continuity before considering the control board

What to check before assuming a major repair

1. Disconnect the dryer from the power supply.
2. Open the access panels carefully—do not force covers or connectors.
3. Perform a visual inspection: look for partially disconnected connectors, frayed cables, burnt or blackened terminals, and corrosion.
4. Check connector seating and terminal condition; re-seat any loose plugs.
5. Measure the NTC resistance with a multimeter at room temperature and verify it changes steadily when heated. An open, fixed, or erratic value indicates a faulty sensor.
6. If the NTC reads correctly, trace and test wiring continuity from the sensor to the board; repair any damaged conductors.
7. Only after the sensor and wiring pass tests should you suspect the control board interpretation or input circuit.

Why you should not keep using the dryer with C8 active

Forcing operation with an unreliable thermal reading leads to repeated interruptions, longer cycles, higher energy consumption, and unnecessary wear on other components. Poor thermal control can also damage clothes—especially delicate or synthetic fabrics—and leave garments damp or with retained odors. Treat C8 as a precision alert that deserves prompt attention to avoid escalation.

What a technician does when diagnosing C8

1. Systematic checks: continuity, resistance, and connector condition.
2. Inspect the probe’s mounting area for heat or mechanical damage.
3. Replace the NTC if readings are out of range or inconsistent.
4. Repair or replace wiring and connectors if signal loss occurs along the path.
5. Only if sensor and wiring are confirmed good does the technician evaluate the control board and its input circuitry.
6. Prefer targeted replacement over random part swaps to save time and cost.

Practical safety tips and recommendations

• Always disconnect power before opening the dryer.
• Avoid forcing panels or connectors; use the correct tools.
• Use a multimeter to confirm NTC resistance and wiring continuity.
• If you are not comfortable with electrical diagnosis, call a qualified technician—electrical faults rarely improve with continued use.
• Use the free error code finder to guide your troubleshooting and confirm recommended steps.

Final note

C8 is a clear, specific warning: a loss of reliable thermal measurement. Start with visual checks, test the probe and wiring, and only then consider the control board. Acting promptly keeps repair costs down, protects garments, and prevents the fault from affecting other components.
