Overview of Craftsman Garage Door Opener 139.536 Parts
The Craftsman Garage Door Opener 139.536 model has a range of components that work together to lift and lower your garage door. Knowing these parts and their functions will help you diagnose any potential issues and determine when a part needs replacement. Below are some of the primary components that make up this model:
- Motor Unit: The motor powers the opener, enabling it to lift and close the garage door. It’s designed to handle frequent use and comes with built-in safety features.
- Drive System (Chain or Belt): This part transfers the motor’s power to the trolley, moving the door up and down. Chain drives are typically durable, while belt drives operate more quietly.
- Trolley and Rail Assembly: The trolley travels along the rail, moving the garage door. It connects to the door arm to pull the door open and push it closed.
- Safety Sensors: Positioned near the base of the door frame, these sensors stop the door from closing if an object or person is in the way.
- Control Panel: The wall-mounted control panel allows users to open or close the door from inside the garage and may include additional programming options.
- Remote Controls and Keypad: Remotes and optional keypads offer remote control access to open or close the door.
- Limit Switches: Limit switches control the distance the door travels when opening and closing, ensuring it stops at the right points.
- Lights and Light Lens Covers: Lights attached to the motor unit provide illumination in the garage when the door operates. The lens covers protect these lights.
Craftsman Garage Door Opener 139.536 Parts: Understanding Each Component
Knowing how each part functions helps you identify the causes of issues and maintain your garage door opener effectively. Below, we provide more detail on each of these Craftsman Garage Door Opener 139.536 parts.
1. The Motor Unit
The motor is the heart of the garage door opener, providing the power needed to lift and close the door. Over time, dust and wear can reduce motor efficiency, so it’s important to keep this part well-maintained.
- Maintenance Tip: Dust the motor unit regularly and check for any unusual noises, which may indicate wear. If the motor begins to struggle with lifting the door, it may need servicing or replacement.
2. Chain or Belt Drive System
The Craftsman 139.536 model typically uses either a chain or a belt to drive the door. Chain drives are durable and great for heavy doors, while belt drives are quieter and may be preferable in attached garages.
- Maintenance Tip: Lubricate the chain drive every six months with garage door lubricant to prevent rust and wear. Belt drives generally don’t need lubrication but should be checked regularly for any signs of fraying.
3. Trolley and Rail Assembly
The trolley moves along the rail, connecting to the door arm to control the door’s movement. This assembly can wear out due to frequent use or if not regularly lubricated.
- Maintenance Tip: Apply lubrication to the rail every few months and check for signs of wear. If the trolley becomes difficult to move, consider replacing it.
4. Safety Sensors
Safety sensors ensure the garage door doesn’t close if something or someone is in its path, which is an essential safety feature. The sensors must be aligned correctly to work properly.
- Maintenance Tip: Clean the sensor lenses regularly and ensure they are aligned. Misaligned or dirty sensors can prevent the door from closing properly, triggering the safety reversal.
5. Control Panel
The control panel allows you to operate the garage door from inside the garage. Some panels also allow for programming remote controls and setting additional features.
- Maintenance Tip: Ensure the control panel’s wiring is secure and test it regularly. If the buttons don’t respond or the panel malfunctions, it may need replacement.
6. Remote Controls and Keypad
Remote controls and keypads provide added convenience, allowing you to operate the door without being near the control panel. Remotes often need battery replacement, and keypads may require programming updates over time.
- Maintenance Tip: Replace remote batteries annually and test the keypad’s functionality. Refer to the manual if reprogramming is needed or if the keypad does not work consistently.
7. Limit Switches
Limit switches control how far the door opens and closes. These are essential for preventing the door from going too far in either direction, which can cause strain on the opener.
- Maintenance Tip: Check the limit switch settings periodically. If the door doesn’t fully open or close, adjusting the limit switches may resolve the issue.
8. Lights and Light Lens Covers
Lights on the motor unit provide illumination for safe garage access. Over time, bulbs may need replacement, and the light covers should be kept clean.
- Maintenance Tip: Replace the bulb with a compatible garage door opener light and clean the lens cover to ensure maximum light output.
