Step-by-Step: How To Remove Cover on Chamberlain Garage Door Opener
Step 1: Disconnect Power
This is the most critical step.
- Unplug the opener from the ceiling outlet
- If hardwired, switch off the breaker
- Wait 30–60 seconds to allow residual power to discharge
⚠️ Never work on the opener while it’s powered.
Step 2: Make Sure the Garage Door Is Closed
- Ensures stability

- Reduces tension on internal parts
You do not need to disconnect the door or trolley.
Step 3: Locate the Cover Screws or Tabs
Depending on the model, the cover may be secured by:
- 2–4 screws (rear or sides)
- Snap-in plastic tabs
- Screws hidden near the light lenses
Check all sides of the motor housing carefully.
Step 4: Remove the Screws
- Support the cover with one hand
- Use a Phillips screwdriver to remove screws
- Place screws in a small container
Most screws are 1–1.5 inches long and reusable.
Step 5: Release Snap Tabs (If Present)
If the cover doesn’t come loose after removing screws:
- Gently pull downward
- Slide the cover slightly backward
- Use a flat-head screwdriver to press release tabs
⚠️ Use light pressure only—do not pry aggressively.
Step 6: Lower and Remove the Cover
Once released:
- Tilt the cover downward
- Carefully clear the light bulbs
- Set the cover aside on a flat surface
You now have full access to the opener’s internal components.

These tasks are safe if you avoid electrical contact points.
What You Should NOT Touch Inside
