Kenmore Dryer Service Manual

The Kenmore Dryer Service Manual provides comprehensive technical information for authorized service technicians. It covers safety procedures, diagnostic troubleshooting, component testing, disassembly/assembly instructions, wiring diagrams, and parts lists for various Kenmore dryer models. This manual is essential for proper maintenance, repair, and verification of dryer operation. Below are key sections for safety, diagnostics, component testing, repair procedures, and technical specifications.

Safety Precautions

Before servicing, disconnect power at the circuit breaker or unplug the dryer. Allow time for components to cool. Use insulated tools.

Hazard	Precaution
Electrical Shock	Verify power is disconnected. Use a multimeter to test for voltage.
High Temperature	Allow dryer drum, heating element, and exhaust system to cool completely.
Moving Parts	Ensure drum and motor are free to move before applying power during testing.
Gas Models	Check for gas leaks with soap solution after any gas line service. Do not use open flame.
Sharp Edges	Wear cut-resistant gloves when handling cabinet panels and internal brackets.

Model Identification

Locate the model and serial number tag. It is typically found inside the door opening, on the rear panel, or on the frame near the control console.

1. Record the full model number (e.g., 110.XXXXXXX).
2. Record the serial number.
3. Verify parts and procedures are correct for the specific model.

WARNING! Using incorrect parts or procedures for the model can cause improper operation or safety hazards.

Diagnostic Mode & Error Codes

Many electronic control models feature a diagnostic mode. Enter by pressing a specific button sequence on the console.

1. Enter Diagnostics: Common sequences include holding "Start" and "Cancel" for 3 seconds.
2. Navigate Codes: Use arrow or cycle buttons to scroll through stored fault codes.
3. Interpret Codes: Refer to code chart (e.g., F1 = Thermal Fuse Open, F5 = Door Switch Fault).
4. Clear Codes: After repair, clear codes via diagnostic menu or by disconnecting power for 1 minute.

CAUTION! Do not bypass safety devices indicated by error codes. Replace faulty components.

Component Testing

• Heating Element (Electric): Disconnect power. Test for continuity across terminals; resistance should be low (approx. 10-50 Ω). Also test for continuity to the housing (should be infinite/open).
• Thermal Fuse: Test for continuity. No continuity indicates a blown fuse. Identify and correct the cause (overheating, restricted vent) before replacement.
• Thermostat (Cycling & High-Limit): Test for continuity at room temperature. Some require heat to open; follow specific testing procedure.
• Motor: Test windings for continuity and resistance per specifications. Check the centrifugal start switch.
• Timer/Motor Switch & Electronic Control Board: Use wiring diagram to verify voltage inputs/outputs. Control boards are often diagnosed by process of elimination of other components.
• Door Switch: Test for continuity when the door is closed (circuit closed) and open (circuit open).
• Gas Valve Solenoids (Gas Models): Test coil resistance against specifications.
• Igniter (Gas Models): Test for continuity; typical resistance is 50-400 Ω. Visually check for cracks.
• Moisture Sensors: Clean with mild abrasive pad. Test conductivity/resistance per manual.

Disassembly Instructions

General steps to access internal components. Sequence may vary by model.

Accessing the Drum & Belt:

1. Unplug dryer and move it to a service area.
2. Remove the top panel: Insert a putty knife at the front corners to release spring clips, lift panel up and back.
3. Remove the front panel: Open door, remove screws from inside the door opening, lift panel up and off.
4. Release belt tension and slide belt off motor pulley and idler pulley.
5. Lift the drum out of the cabinet.

Accessing the Rear Components:

1. Remove the rear service panel screws.
2. Lower the panel to access heating element, thermostats, fuses, and blower housing.

Accessing the Control Console:

1. Remove screws at the ends of the console or under the lip.
2. Lift the console and support it. Disconnect wire harness connectors carefully.

Common Repair Procedures

Replacing the Drive Belt:

1. Disassemble to access drum as described.
2. Route the new belt around the drum, idler pulley, and motor pulley according to the diagram inside the dryer.
3. Ensure the idler pulley spring provides proper tension.
4. Reassemble and test. The drum should rotate smoothly with no squealing.

Replacing the Heating Element (Electric):

1. Gain access to the rear compartment.
2. Disconnect wires, noting their positions.
3. Remove mounting screws or brackets holding the element.
4. Install new element, ensuring it does not touch the housing. Reconnect wires correctly.
5. Replace thermal fuse and high-limit thermostat if recommended or if cause of element failure is unknown.

Replacing the Thermal Fuse:

1. Locate fuse (often on heater housing or exhaust duct).
2. Disconnect wires and remove mounting clip or screws.
3. Install new fuse of the exact same rating. Ensure venting is clear to prevent recurrence.

Cleaning the Lint Filter Housing & Exhaust Duct:

1. Remove lint filter. Use a vacuum and lint brush to clean the filter cavity.
2. Disconnect the dryer from the wall vent. Clean the flexible or rigid duct thoroughly.
3. Check the external wall cap for obstruction.

Wiring Diagrams & Schematics

Refer to the model-specific wiring diagram for all electrical connections. Diagrams show component locations, wire colors, connector references, and switch logic.

1. Identify the main power circuit (L1, L2, Neutral).
2. Trace the motor circuit through the door switch, timer/control, and start switch.
3. Trace the heater circuit (electric) through the cycling thermostat, high-limit thermostat, thermal fuse, and safety switches.
4. For gas models, trace the ignition control circuit through the flame sensor, gas valve solenoids, and igniter.

Tip: Use a highlighter to mark the circuit you are diagnosing on the diagram.

Parts List & Exploded Views

Exploded-view drawings show the relationship and order of all parts. The accompanying parts list provides the manufacturer's part number and description.

1. Locate the assembly (e.g., "Cabinet Assembly," "Drive Motor Assembly") in the drawings.
2. Identify the reference number for the needed part.
3. Find the corresponding reference number in the parts list to get the correct part number for ordering.
4. Common replacement parts include: drive belt, idler pulley, rollers, heating element, thermal fuse, thermostats, door switch, motor, and control board.

WARNING! Use only Kenmore-approved replacement parts to ensure safety and proper operation.

Reassembly & Verification

After repair, reassemble in reverse order of disassembly. Ensure all screws are tightened, connectors are fully seated, and no wires are pinched.

Operational Verification Test:

1. Plug in dryer or restore power.
2. Start a timed dry cycle on low heat (for electric) or air fluff (for initial test).
3. Verify: Drum rotates, blower operates (feel exhaust air), no unusual noises.
4. For heat test: Start a cycle on high heat. Verify heater energizes after the motor is running (electric: element glows; gas: igniter glows and flame lights).
5. Verify automatic shut-off at the end of cycle or when door is opened.

CAUTION! Do not leave the dryer unattended during initial verification after a major repair.
