Parts for Mcculloch PRO MAC 650: Carburetor Assembly Parts

This atmospheric analyser is a diagnostic sensor that monitors combustion air characteristics so the appliance can adjust operation and run safely. It helps detect abnormal air/combustion conditions that affect performance or safety. What it does:

• Measures atmospheric/combustion air parameters used by the appliance control for safe operation
• Helps the control detect poor combustion conditions or air supply problems
• Can prevent improper burner operation by signalling abnormal readings
• Common symptom: appliance fails to light, runs intermittently, or shows fault codes related to air/combustion sensing

• One atmospheric analyser

• Disconnect power and gas supply before servicing to avoid shock or fire hazards
• Handle the sensor carefully to avoid contamination; follow OEM alignment and torque instructions
• Verify correct part number on the appliance and test appliance operation after installation

This atmospheric analyser is a sensor module that monitors air/gas conditions inside the appliance to help the control system detect unsafe or out-of-range combustion/ventilation conditions. Replacing a faulty analyser restores proper monitoring for safe operation. What it does:

• Senses internal air/gas conditions used by the appliance control to confirm safe combustion/venting
• Helps the appliance detect conditions that can trigger safety shutdowns or error codes
• Faulty units can cause ignition failures, repeated safety lockouts, or venting-related error messages
• Works as part of the appliance's safety and control system

• One atmospheric analyser sensor module

• Disconnect electrical power and shut off the gas supply before servicing gas appliances
• Handle the sensor carefully; avoid touching sensing surfaces or connector pins
• Reconnect and test appliance operation after installation; confirm no error codes remain

This replacement tube is a direct-fit connector used to route water or other fluids within the appliance, restoring proper flow and sealing to help prevent leaks and interruptions in operation. What it does:

• Routes water or fluid between components to maintain proper system flow
• Provides a sealed connection to help prevent drips and leaks
• Replaces cracked, split, or clogged tubing that can cause poor performance
• Helps stop intermittent water flow interruptions or unexpected leaks

• One replacement tube/connector as shown

• Install only when the appliance is powered off and water supply is shut off
• Confirm orientation and seating to avoid pinches or kinks that can restrict flow
• Use compatible clamps or fittings provided by the appliance manufacturer
