Problem: Door Lock Error (Specific to dryers with door lock safety mechanisms). The dryer cannot verify the door is locked before operation.

How to Fix Dryer Error

1. Unplug the dryer.
2. Check for an obstruction in the door latch hole.
3. Remove the front panel to access the electronic door lock assembly.
4. Inspect the wiring harness for damage.
5. If wiring is intact, replace the electronic door lock assembly.

Problem: Thermistor Error 1. The thermistor located on the blower housing (or near the heater, depending on model) has failed or provides an abnormal resistance reading.

How to Fix Dryer Error

1. Unplug the dryer.
2. Remove the top and front panel (or rear panel on some models) to access the blower housing.
3. Locate the thermistor (small white sensor with 2 wires).
4. Measure resistance with a multimeter; at room temperature (70°F), it should read approximately 10k Ohms.
5. If the reading is infinite (open) or zero (shorted), replace the thermistor.

Problem: Thermistor Error 2. The secondary thermistor (often on the ductwork) is reading open or shorted. Often occurs if ambient temperature is below 40°F.

How to Fix Dryer Error

1. Ensure the room temperature is above 45°F.
2. Unplug the dryer and remove the panel covering the heating duct.
3. Locate the secondary thermistor.
4. Unplug the connector and test resistance (should be approx 10k Ohms at room temp).
5. If resistance is out of range, replace the thermistor.

Problem: Thermistor Error 3. The thermistor detected a temperature change that is too rapid or inconsistent with the heating profile.

How to Fix Dryer Error

1. Unplug the dryer.
2. Check the wiring harness connecting the thermistor to the main board for pinched wires.
3. Remove the thermistor and clean any lint buildup on the metal sensor head.
4. Test resistance (10k Ohms at 77°F).
5. Replace the thermistor if wiring is good.

Problem: Thermistor Error 4. Specific to Heat Pump/Hybrid dryers. The compressor thermistor is faulty.

How to Fix Dryer Error

1. Unplug the dryer.
2. Access the compressor compartment (usually requires significant disassembly).
3. Locate the thermistor attached to the compressor lines.
4. Test resistance against the tech sheet chart (values vary by heat pump model).
5. Replace the thermistor if out of spec.

Problem: Temperature sensor error. Equivalent to tE1 on older models.

How to Fix Dryer Error

1. Unplug the dryer.
2. Remove the top and front panel (or rear panel on some models) to access the blower housing.
3. Locate the thermistor (small white sensor with 2 wires).
4. Measure resistance with a multimeter; at room temperature (70°F), it should read approximately 10k Ohms.
5. If the reading is infinite (open) or zero (shorted), replace the thermistor.

Problem: Humidity Sensor Error. The control board detects a short or open circuit in the moisture sensor bars located inside the drum near the lint filter.

How to Fix Dryer Error

1. Open the door and locate the two metal bars near the lint filter.
2. Clean the bars with vinegar and a cloth to remove fabric softener residue.
3. If code persists, unplug dryer and remove the top panel.
4. Trace the wire harness (usually orange) from the sensor bars to the main board.
5. If wiring is intact, replace the moisture sensor bar assembly and harness.

Problem: Button Error. A button on the user interface is stuck in the pressed position.

How to Fix Dryer Error

1. Unplug the dryer.
2. Massage all buttons on the control panel to see if one is physically stuck or depressed.
3. Press each button firmly and listen for the ‘click’ of the tactile switch.
4. If buttons move freely but the code remains, the user interface board is faulty and requires replacement.

Problem: Gas Valve Motor Error. The main board does not detect the gas valve coils opening or the igniter functioning correctly.

How to Fix Dryer Error

1. Unplug the dryer.
2. Remove the front panel to access the gas burner assembly.
3. Test the two solenoid coils for continuity.
4. Test the igniter for resistance (approx 50-400 Ohms).
5. If coils and igniter are good, inspect the flame sensor.
6. Replace the defective component (usually the solenoid coils).

Problem: Drain Error (Hybrid/Condenser models). The condensate drawer is full or the drain hose is kinked.

How to Fix Dryer Error

1. Remove and empty the water collection drawer (if equipped).
2. Check the drain hose at the back of the unit for kinks or clogs.
3. If the hose is clear, the drain pump may be failed.
4. Access the drain pump and test for 120V supply when the cycle starts.
5. Replace the drain pump if it receives voltage but does not pump.
