– 22 –4. Remove the 2 Phillips-head screws from themetal duct.5. Pull the metal duct off the lint filter housing.6. Remove the 2 Phillips-head screws from the lintfilter housing.7. Lift the lint filter housing and remove it from thefront bulkhead.8. Remove the 9/16-in. hex nut that attaches theshaft to the front bulkhead.To remove the drum roller shaft from the rearbulkhead:1. Remove the drum. (See Drive Belt and Drum.)2. For front service, tilt the bottom of the rearbulkhead inward from the dryer frame (See RearBulkhead.), or remove the back panel for rearservice. (See Back Panel.)3. Remove the 9/16-in. hex nut that attaches thedrum roller shaft to the rear bulkhead.Metal DuctLint Filter HousingNote: The 2 sensor rods in the front bulkhead arenot replaceable. To replace the sensor rods, replacethe lint filter housing. (See Drum Rollers.)• The sensor rods are connected to themain control board. The rods are spacedapproximately 1/2 inch apart, creating an opencircuit to the control.• The control board utilizes a low-voltagecapacitor that charges to approximately 5 VDCwhen the circuit is open and discharges to lessthan 1 VDC when the circuit is shorted.• When wet clothes tumble across the 2 rods, theclothes create a very low resistance betweenthe rods, discharging the capacitor.• As the clothes become dry, their resistancevalue increases and the charge across thecapacitor builds to approximately 5 VDC.• Proper leveling of the dryer is vital for accuratesensor drying. If the front of the dryer is raisedtoo high, clothes will tumble toward the rear ofthe drum, preventing contact with the sensorrods. This could produce a false dryness reading.Moisture SensorThe moisture-sensing circuit consists of 2 sensorrods. They are mounted beneath the lint filter on thedrum side of the front bulkhead.
