This Zener diode is a replacement semiconductor designed to regulate voltage and protect control circuitry from spikes. It restores stable operation by clamping voltage in power and control boards. What it does:

• Provides voltage regulation to protect sensitive components from over-voltage conditions
• Helps prevent damage from transient spikes that can cause erratic control-board behavior
• Commonly used on power supply and main control boards to stabilize reference voltages
• Can resolve symptoms like intermittent power issues, error codes, or boards that fail to start when caused by a failed clamp

• One Zener diode as shown

• Replace only with matching part number or equivalent specification; incorrect diodes can damage circuits
• Observe ESD precautions and disconnect power before servicing
• Soldering skills required; avoid excessive heat to prevent board or part damage

This small chip resistor is a direct replacement circuit resistor used on appliance control boards to restore proper current flow and stable operation. It helps fix control-board faults caused by a failed resistor component. What it does

• Limits or regulates electrical current within the control board circuit
• Restores correct voltage drop for related board components and sensors
• Can resolve symptoms like intermittent operation, control errors, or components not responding
• Prevents further board stress when the resistor value has drifted or failed

• One replacement chip resistor

• Intended for board-level replacement; soldering skills and proper ESD precautions required
• Disconnect main power before servicing the appliance to avoid shock
• Verify component marking and board location before removing the old part

This fixed cement resistor is a durable through-hole resistor used in appliance control circuits to limit current and stabilize voltage, helping electronics run safely and reliably. What it does:

• Provides a fixed resistance value in control and power circuits to limit current flow
• Helps protect sensitive components from current spikes and contributes to stable operation
• A failed or burned resistor can cause loss of function, intermittent operation, or blown fuses
• Commonly mounted on control boards or chassis where higher power dissipation is required

• One fixed cement resistor as shown

• Disconnect power and unplug the appliance before attempting service
• Discharge capacitors and wait for components to cool before handling the board
• Replace with the exact resistance and wattage specification; do not substitute without verification

A fixed metal resistor used in appliance control circuits to provide a precise resistance value for proper operation. Replaces a worn or failed resistor to restore stable electrical performance and help eliminate related faults. What it does:

• Provides a specific, fixed resistance in a control or sensor circuit to regulate current or signal levels
• Helps maintain correct control board sensing and operation when functioning properly
• Common symptom of a failed resistor: appliance shows error codes, intermittent operation, or certain functions won't engage
• Can prevent further electrical issues by restoring the intended circuit resistance

• One fixed metal resistor

• Disconnect power to the appliance before servicing to avoid shock or damage
• Handle the part carefully and avoid bending leads or damaging solder joints

This is a replacement KRA103M transistor used on appliance control electronics to regulate and switch electrical signals. Replacing a faulty transistor can restore reliable operation of electronic circuits and controlled components. What it does:

• Switches and regulates current on the control board to allow proper function of electronic circuits
• Helps control power to components that rely on the board's signals
• Corrects symptoms such as intermittent control response, components not powering, or erratic electronic behavior
• Small electronic replacement; requires proper handling and mounting to ensure reliable contact

• Disconnect power to the appliance before servicing to avoid shock or damage
• Use ESD-safe handling to protect the transistor and the circuit board
• Installation typically requires soldering; inspect surrounding components and board pads for heat damage when replacing

This replacement transistor restores proper switching and control on compatible appliance control boards, helping the unit run reliably and preventing intermittent failures. Use this transistor to replace a damaged or non-responsive switching component. What it does:

• Acts as a switching element on the appliance control/inverter board to enable motor, compressor, or heater control
• Can stop symptoms such as no-start, intermittent operation, or loss of specific functions when a transistor has failed
• Transfers control signals and helps regulate current flow for associated circuits
• Works as a direct replacement for the failed transistor on the original board

• Only install on the matching control board and orientation
• Disconnect power to the appliance before servicing to avoid shock or damage
• Handle the transistor and PCB with anti-static precautions when possible

This replacement pack contains bipolar transistors used on control and power boards to switch and amplify low-voltage signals. Replacing failed transistors restores reliable switching and board operation. What it does

• Acts as a semiconductor switch and amplifier on control/power circuits
• Can stop intermittent or non-functioning board outputs when failed
• Addresses symptoms such as loss of function, intermittent operation, or electrical faults tied to a control board
• Works with PCB-mounted circuits that require matched bipolar transistor replacements

• Board-level replacement only; remove power and discharge capacitors before service
• Use proper ESD precautions and soldering skills
• Verify transistor orientation and board markings before soldering

This shaft provides a secure mounting point for the dryer drum so it turns smoothly and stays aligned. Replacing a worn shaft restores even drum rotation and reduces noise and scraping during operation. What it does

• Supports the drum at the rear and lets it rotate on the rear bearing or glide
• Keeps the drum aligned to prevent rubbing, dragging, and uneven wear
• Helps eliminate squealing, grinding, or scraping noises caused by a worn or bent shaft
• Works with the drum bearing/bushing and support assembly to maintain smooth operation

• One replacement shaft

• Disconnect power before beginning any repair; the appliance is fully de-energized
• Access typically requires removing the dryer cabinet and drum; support the drum during removal
• Inspect bearings, bushings, and seals while replacing the shaft and replace any worn parts
• Use appropriate hand tools and follow OEM service manual steps
