Here are some steps you can follow to identify and repair the problem:
1. Check the limit switch: Disconnect power from the garage door opener and carefully remove the cover to expose the internal mechanism. Locate the limit switch, which is usually a small black or brown switch with two wires attached to it. Press the button on the limit switch to test if it is working. If the switch does not click or activate the door, it may need to be replaced.
2. Inspect the photo eye sensors: The photo eye sensors are located near the bottom of the garage door and are responsible for detecting objects in the path of the closing door. Ensure the sensors are clean, free of obstructions, and properly aligned. If the sensors appear damaged or misaligned, they may need to be replaced or adjusted.
3. Verify the wiring: Check the wiring connections to the limit switch and photo eye sensors to make sure they are secure. Loose or disconnected wiring can prevent the door from reversing properly. Tighten any loose connections or replace damaged wiring as necessary.
4. Follow manufacturer's instructions: Refer to the user manual or installation guide provided by Nutone for specific instructions on how to repair your garage door opener model. The manual may include detailed troubleshooting steps and instructions for replacing defective components.
5. Consult a professional: If you are uncomfortable performing the repairs yourself or if the issue persists, it's best to contact a professional garage door repair technician. They can accurately identify the problem and ensure that the door is functioning safely.
Remember to take safety precautions when working on garage door openers, as they involve electrical components and moving parts. If you are unsure about any step or procedure, consult with a qualified technician to avoid causing further damage.
