Problem: Door Error (General). The main control board does not detect that the door is closed.

How to Fix Dryer Error

1. Open the door and inspect the latch assembly for physical damage.
2. Locate the door switch plunger.
3. Press the plunger manually while starting the dryer; if it starts, the door hinge is sagging.
4. If it does not start, unplug the dryer and remove the top panel/front panel to access the switch.
5. Test the switch for continuity with a multimeter.
6. Replace the switch if it shows no continuity when pressed.

Problem: Door Error 1. The control board assumes the door is open while the cycle is running, or the switch circuit is open.

How to Fix Dryer Error

1. Unplug the dryer.
2. Remove the top panel to access the door switch wiring.
3. Check the wire harness connecting the door switch to the main PCB for breaks or loose connections.
4. Test the door switch for continuity (should be closed when button pressed).
5. If the switch and wiring are good, the main control board door-sensing circuit has failed and the board must be replaced.

Problem: Door Error 2. The control board assumes the door is CLOSED when it should be open (Switch contacts welded shut).

How to Fix Dryer Error

1. Unplug the dryer.
2. Disconnect the door switch wire harness.
3. Use a multimeter to test the switch terminals without pressing the button.
4. If there is continuity (beep) without pressing the button, the switch is stuck closed.
5. Replace the door switch.

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.
