- Brush each sensor strip 5-6 times to dislodge fabric softener residue, lint particles, and mineral deposits that appear as white, gray, or translucent film on the metal surface.
- Hold a can of compressed air (standard electronics duster with minimum 50 PSI) 4 inches away from the sensor strips at a 45-degree angle.
- Spray compressed air in 2-second bursts across each sensor strip, moving the can from top to bottom, repeating 3 times per strip.
- Direct compressed air into the 0.125-inch gap between the sensor strips and the white plastic backing plate using the narrow red straw attachment included with the compressed air can.
- Wipe each sensor strip with a clean, dry microfiber cloth using vertical motions to remove loosened debris, applying light pressure equivalent to writing with a pencil.
- Inspect both sensor strips under good lighting—they should appear uniformly silver/metallic with no visible residue, discoloration, or buildup remaining.
- Check the surrounding plastic housing for lint accumulation within 2 inches of the sensor assembly, using the soft brush and compressed air to clean this area using the same technique.

âś… Step 6: Remove any lint or debris from sensor area
- Locate the moisture sensor strips inside the drum – these are two parallel metal bars mounted on the rear drum wall, positioned horizontally approximately 4 inches from the top edge and spaced 2 inches apart.
- Dampen a microfiber cloth with distilled white vinegar (do not use tap water, as minerals will coat the sensors).
- Wring the cloth until it’s just barely damp – no liquid should drip from it.
- Wipe each metal sensor strip lengthwise using firm, straight strokes, applying moderate pressure equivalent to wiping a kitchen countertop. Make 3-4 passes along each strip.
- Inspect the sensors under good lighting – the metal surface should appear shiny and uniform. If you see white residue, fabric softener buildup, or lint fibers still adhering to the metal, repeat step 4.
- Check the mounting brackets at each end of the sensor strips (small plastic clips holding the sensors in place) – use a dry cotton swab to remove any lint accumulated in the gaps between the bracket and drum wall.
- Run your finger along each sensor strip – the surface should feel completely smooth with no tackiness or rough patches.
- Examine the area 2 inches around the sensors on the drum wall for lint accumulation. Use a dry microfiber cloth to wipe this area clean using circular motions.
- Allow sensors to air-dry for 2 minutes before proceeding.
- Verify cleaning success by looking at the sensors from a side angle with a flashlight – you should see clear reflections on the metal surface with no dull spots or residue streaks.
🔍
🔍 Step 7: Check sensor connections for proper contact
- Locate the moisture sensor assembly at the front of the drum opening, mounted on the lower right side approximately 2 inches up from the bottom seal and 3 inches in from the right edge.
- Identify the two metal sensor bars protruding approximately 1/4 inch into the drum chamber – these are flat rectangular strips, each measuring roughly 3 inches long and 1/4 inch wide.
- Use a clean, dry microfiber cloth to wipe both sensor bars thoroughly, removing any lint, fabric softener residue, or mineral deposits that appear as white or gray film.
- Remove the single T20 Torx screw securing the sensor bracket to the front panel, located directly below the sensor bars.
- Pull the sensor assembly forward approximately 1 inch to expose the wire connector on the back side.
- Locate the white plastic connector with 2 wires (typically one blue and one brown) attached to the sensor assembly.
- Press the release tab on top of the connector housing and pull the connector straight back to disconnect it.
- Examine the male pins inside the connector – you should see 2 brass-colored pins that are straight, not bent, and free from corrosion or discoloration.
- Inspect the female socket terminals on the sensor assembly – push gently on each terminal with a small flathead screwdriver to verify they have spring tension and aren’t pushed back into the housing.
- If terminals appear loose, use needle-nose pliers to gently squeeze the sides of each female terminal inward by 1/32 inch to increase contact pressure.
- Reconnect the white plastic connector by aligning the pins and pushing firmly until you hear and feel a distinct click.
- Tug on the connector with moderate force – it should not separate without pressing the release tab.
- Reposition the sensor assembly flush against the front panel and reinstall the T20 Torx screw, tightening until snug but not overtightened.
🧪
đź’ˇ Step 8: Test sensor operation
- Locate the moisture sensor strips inside the drum—two parallel metal strips positioned on the back wall of the drum, approximately 3 inches from the top edge and 8 inches apart from each other.
- Set your multimeter to the resistance (ohm) setting at the 20K ohm range.
- Touch one multimeter probe to the left sensor strip and the other probe to the right sensor strip while the drum is completely dry—the reading should show “OL” (open line) or infinite resistance.
- Dampen a cotton cloth with water (not soaking wet, just damp) and drape it across both sensor strips so it makes contact with both metal surfaces simultaneously.
- Keep the multimeter probes touching the sensor strips—the resistance reading should drop to between 10K and 100K ohms, indicating the sensors detect moisture through the damp fabric.
- Remove the damp cloth and wipe the sensor strips dry with a clean towel—the multimeter reading should return to “OL” or infinite resistance within 5 seconds.
- Plug the dryer back into the wall outlet and turn the circuit breaker on.
- Press the power button on the control panel—the display should illuminate.
- Select the “Cotton/Normal” cycle by rotating the program selector dial clockwise until it clicks into the Cotton position (typically 2 clicks from the Off position).
- Place the same damp cloth inside the drum directly on the sensor strips.
- Close the door until it clicks and press the Start button—the drum should begin rotating and the display should show an estimated time, usually between 45-60 minutes.
- Wait 30 seconds, then open the door—the cycle should pause immediately.
- Remove the cloth, close the door, and press Start again—the dryer should complete the cycle within 2-3 minutes since no moisture is detected, confirming the sensors are functioning correctly.

⚡ Step 9: Reinstall lint filter properly
- Hold the lint filter by its handle with the mesh screen facing toward you and the handle positioned at the top.
- Locate the lint filter housing opening at the front lower section of the dryer door opening, positioned 2 inches below the door seal on the left side.
- Align the lint filter so the wider bottom edge faces downward and the narrow top section with the handle aligns with the vertical slot in the housing.
- Insert the lint filter into the housing at a straight vertical angle, sliding it downward into the channel until you feel initial resistance (approximately 8-9 inches of travel).
- Apply firm downward pressure on the handle using the palm of your hand, pushing the filter the final 1 inch until you hear and feel a distinct click as the locking tab engages.
- Verify proper seating by pulling upward on the handle with moderate force (approximately 5-10 pounds of pressure)—the filter should not move more than 1/8 inch.
- Check the foam seal strip running along both vertical edges of the lint filter frame; this gray foam strip should sit flush against the housing walls with no gaps or rolled edges visible.
- Remove and reinsert the filter once to confirm smooth operation—the filter should slide in and out without catching or requiring excessive force.
- Look at the top edge where the handle meets the dryer cabinet; you should see no more than 1/16 inch gap between the filter frame top and the housing opening.
- Push the door closed and verify it latches completely—an improperly seated lint filter will prevent the door from closing flush or the dryer from starting.
