Safety notice
Safety: Do not attempt live electrical testing, bypass safety switches, or open sealed refrigeration systems. If you are unsure, call a professional.
Safe homeowner checks
- Power cycle the appliance (turn off/unplug for 60 seconds, then restart).
- Confirm the breaker is fully on (some appliances use two linked breakers).
- Check for obvious blockages (filters, drain hose kinks, lint buildup) where applicable.
- If the code returns, take a photo of the display and note when it appears (start, mid-cycle, heating, draining) — it helps diagnose dryer issues faster.
Stop DIY and call a technician if…
- You smell burning, see smoke, or notice sparking.
- There is active leaking or water near electrical components.
- The appliance is overheating or repeatedly trips the breaker.
- The error code returns immediately after basic checks or the unit will not run safely.
Error Codes by Brand
Samsung Dryer Error Codes
Samsung appliance repair in Ottawa
| Error Code | What It Usually Means | Safe Homeowner Check | When to Call Fixer |
|---|---|---|---|
| tE / tS | A thermistor or exhaust temperature reading is out of range. Heat may shut off to protect the dryer. | Clean the lint filter and confirm strong exhaust airflow at the exterior vent cap. Do not bypass sensors or run the dryer unattended while this code is active. | Fixer can test thermistor resistance, wiring, and heater circuit control rather than replacing sensors by guesswork. |
| hE / HE / HC | The heating circuit did not reach the expected temperature, or the control detected a heater-related fault on this electric dryer. | Clean the lint filter, confirm the vent path is clear, and run one short timed dry cycle. Avoid running high-heat cycles until airflow is confirmed. | If no heat continues after basic vent checks, Fixer can test the heating element, fuses, thermistors, wiring, and control-board output. |
| dC / dE / dF | The door is not closed properly, the door switch does not confirm a safe position, or a drum/airflow interlock is open. | Close the door firmly and check for clothing caught in the seal. Power cycle once. Do not operate the dryer if the door feels loose. | Fixer can test the door switch, latch, and related wiring before heat circuits are used again. |
| 9E / 9C | A communication or power fault was detected between control boards, or voltage supply is unstable for the selected heat setting. | Confirm the dryer plug is fully seated and the correct breaker is on. Avoid extension cords. Power off once, wait 60 seconds, then try a short timed dry. | If 9E or 9C returns on a known-good outlet, Fixer can test supply voltage, terminal connections, and control-board communication before parts are replaced. |
| FE | The dryer is reporting a filter or exhaust restriction that is limiting airflow through the lint filter or vent path. | Clean the lint filter thoroughly, check the vent hose for kinks, and confirm the exterior vent flap opens when the dryer runs. Avoid long heat cycles until airflow improves. | If FE returns after basic cleaning, Fixer can inspect the blower wheel, internal airflow path, and vent run — restricted vents are a safety concern on electric dryers. |
| CLg / vent / filter / airflow warning | The dryer is reporting clogged or restricted exhaust airflow. Blocked lint filters, crushed vent hoses, and obstructed outside vent caps are common causes. | Clean the lint filter, check that the outside vent flap opens when the dryer runs, and make sure the vent hose behind the dryer is not crushed or kinked. | If the warning returns after basic cleaning, Fixer can diagnose airflow restriction, the blower path, thermistors, the heater circuit, or control output before parts are replaced. |
LG Dryer Error Codes
| Error Code | What It Usually Means | Safe Homeowner Check | When to Call Fixer |
|---|---|---|---|
| d80 / d90 / d95 / Flow Sense / CL | The dryer is reporting restricted exhaust airflow, a clogged vent path, lint filter blockage, or a check-vent style warning. Higher d80–d95 numbers usually mean more blockage between the dryer and the outside vent cap. | Clean the lint filter, check that the outside vent flap opens when the dryer runs, and make sure the vent hose is not crushed or kinked behind the dryer. | If the warning returns after basic cleaning, Fixer can diagnose airflow restriction, the blower path, thermistors, the heater circuit, or control output before parts are replaced. |
| nP | The dryer does not detect the expected power configuration, or voltage supply is unstable for the selected heat setting. | Confirm the dryer plug is fully seated and the correct breaker pair is on. Avoid extension cords. Power off once, wait 60 seconds, then try a short timed dry. | If nP returns on a known-good outlet, Fixer can test supply voltage, terminal connections, and control-board power input before parts are replaced. |
| PF / PS | A power interruption or power-supply fault was detected during operation. The control may have lost consistent voltage. | Check whether other appliances on the same circuit tripped. Reset the breaker fully off then on. Run one short cycle and note whether the code appears at start or mid-cycle. | Repeated PF or PS codes often point to wiring, terminal, or control-board issues. A technician can confirm the real cause before the board is replaced. |
| tE1 / tE2 / tE3 | A thermistor or temperature sensor reading is out of range. Heat may shut off to protect the dryer. | Clean the lint filter and confirm strong exhaust airflow. Do not bypass sensors or run the dryer unattended while this code is active. | Fixer can test thermistor resistance, wiring, and heater circuit control rather than replacing sensors by guesswork. |
| HS | Humidity or moisture sensing is out of expected range. On some models this relates to steam or moisture detection in the cabinet. | Wipe moisture from the door area, confirm the lint filter and vent path are clear, and avoid steam-dry settings until a basic timed cycle runs cleanly once. | If HS persists, book service to test humidity sensors, wiring, and control-board inputs. |
| dE | The door is not closed properly or the door switch does not confirm a safe closed position before heat or tumble. | Close the door firmly and check for clothing caught in the seal. Power cycle once. Do not operate the dryer if the door feels loose. | Fixer can test the door switch, latch, and related wiring before heat circuits are used again. |
