Why won't my garage door close?

Common reasons include: misaligned safety sensors, obstructions in the door path, broken springs, stripped gears in the opener, or issues with the close limit settings. Check the safety sensors first - they should both have steady lights.

Should I repair or replace my garage door?

Consider replacing if: the door is over 15-20 years old, has significant rust or structural damage, panels are severely damaged, or you want to upgrade to an insulated door. Many issues like springs, cables, sensors, and openers are cost-effective to repair.

What do the blinking lights on my garage door opener mean?

Blinking lights indicate error codes. For LiftMaster/Chamberlain: 1 blink = sensor wire issue, 2 blinks = sensor wire short, 3 blinks = door control wire issue, 4 blinks = sensor misalignment, 5 blinks = motor issue. Use our error code lookup tool for specific diagnosis.

How do I calculate what torsion spring I need?

To calculate the correct torsion spring, you need: door height, door width, door weight, track type, and number of springs. The formula involves IPPT (Inch-Pounds Per Turn) = d^4 × E / (10.8 × D × Na). Use our spring calculator for accurate results.

Can I replace a garage door spring myself?

Torsion spring replacement is dangerous and recommended only for trained professionals due to the extreme tension (over 200 lbs of force). Extension springs are safer for DIY but still require proper safety precautions and tools.

Garage Door Remote Not Working

DIY Friendly5-20 minutes

When your garage door remote stops working, the cause is almost always dead batteries, lost programming, or signal interference. Replace the batteries first—this fixes the problem 50% of the time. If that doesn't work, reprogram the remote to the opener or check for signal interference.

Common Symptoms

Remote doesn't work but wall button does
Remote works only up close to the opener
Remote works intermittently
All remotes stopped working at once
New remote won't program

Possible Causes

•Dead or weak batteries
•Remote lost programming
•Signal interference
•Damaged remote
•Antenna issues on opener
•Circuit board failure in opener
•Lock mode accidentally enabled

How to Fix It

Replace the batteries

Open the remote and replace the battery (usually CR2032 or similar). Even if batteries seem fine, try fresh ones. This solves the issue 50% of the time.

Check lock mode

Many openers have a 'lock' or 'vacation' mode that disables remotes. Check your wall console for a lock button (often with a padlock icon) and ensure it's off.

Reprogram the remote

Find the 'learn' or 'program' button on your opener (usually on the back or side). Press it, then press your remote button within 30 seconds. The opener light should blink to confirm.

Check the antenna

Ensure the antenna wire hanging from the opener is not damaged, coiled up, or tucked away. It should hang straight down for best signal.

Test for interference

LED lights, wireless cameras, or other electronics can interfere with garage door signals. Try unplugging nearby devices to test.

Try a new remote

If nothing else works, the remote may be damaged. Universal remotes are available at hardware stores and work with most openers.

When to Call a Professional

•Wall button and remotes both don't work
•Opener shows no lights or response at all
•You've tried everything and remotes still won't program
•Multiple openers on your street stopped working (possible interference issue)

Frequently Asked Questions

Why does my garage door remote only work sometimes?

Intermittent operation usually means weak batteries, signal interference, or a failing remote. Try fresh batteries first. If that doesn't help, the remote's internal components may be wearing out.

Can LED lights interfere with garage door openers?

Yes, some LED bulbs emit radio frequency interference that can disrupt garage door remotes. Try using 'garage door opener compatible' LED bulbs or switch back to incandescent bulbs in the opener.

How do I reset my garage door opener remote?

To reset/reprogram: locate the 'learn' button on your opener unit, press and hold it until the indicator light turns off (about 6 seconds). This erases all programmed remotes. Then reprogram each remote by pressing the learn button briefly, then pressing the remote button.
