Common Reasons Why Your Craftsman 1 2 Hp Garage Door Opener Will Not Open
There are several reasons why your garage door opener might not be opening. Here are the most common causes:
✔ Power Supply Issues – The opener may not be receiving power.
✔ Remote Control Malfunction – The remote battery may be dead, or the signal is blocked.
✔ Wall Control Panel Problems – The wall button may be defective.
✔ Safety Sensors Misalignment – The sensors might be blocked or misaligned.
✔ Broken Garage Door Springs – The torsion or extension springs might be damaged.
✔ Track and Roller Issues – The door may be off track or obstructed.
✔ Motor Overheating – The motor could be overloaded and need time to reset.
Each of these problems can prevent your garage door from opening properly. Let’s go through detailed troubleshooting for each issue.
Troubleshooting: Craftsman 1 2 Hp Garage Door Opener Will Not Open
1. Check the Power Supply
✔ Ensure the garage door opener is plugged into a working outlet.
✔ If the outlet is dead, reset the circuit breaker or try another device in the same outlet.
✔ Check if the power cord is damaged and replace it if necessary.
✔ If your opener is hardwired, inspect the wiring for loose connections.
If there is no power issue, move on to the next step.
2. Inspect the Remote Control and Wall Panel
✔ Replace the remote control batteries if they are dead.
✔ Stand closer to the garage door and press the remote button again.
✔ If the remote doesn’t work, try the wall-mounted control panel.
✔ If the wall panel works but the remote doesn’t, you may need to reprogram the remote.
✔ If neither works, reset the Craftsman 1 2 Hp Garage Door Opener by unplugging it for 30 seconds and plugging it back in.
If your remote still doesn’t work, check the safety sensors next.
3. Ensure the Safety Sensors Are Aligned
✔ Look for the two sensors at the bottom of the garage door tracks.
✔ Ensure nothing is blocking the sensors (dirt, dust, objects).
✔ Check if the sensor lights are on and not flickering.
✔ If one sensor light is off or blinking, adjust the alignment until both lights are steady.
Misaligned sensors can prevent the garage door from opening, even if everything else is working fine.
4. Check for Broken Garage Door Springs
The garage door springs help lift the door. If they break, the opener may struggle to open the door or not open it at all.
✔ Inspect the torsion springs (located above the garage door).
✔ Check the extension springs (on the sides of the garage door).
✔ If a spring is broken, the door will be too heavy to lift manually.
⚠️ Warning: Replacing garage door springs can be dangerous. It’s best to call a professional for spring replacement.
5. Look for Obstructions on the Tracks
✔ Check if the garage door is off track or if there are any dents, debris, or rust.
✔ Inspect the rollers to ensure they are properly aligned.
✔ Try opening the door manually. If it sticks, the track may be misaligned.
If needed, lubricate the tracks and rollers with garage door lubricant to ensure smooth operation.
6. Test the Garage Door Opener Motor
✔ If the garage door opener makes a humming noise but doesn’t open, the motor might be overloaded.
✔ Unplug the opener for 30 minutes to allow it to cool down.
✔ If the motor is still not working, check for burnt-out internal components.
✔ If the motor is faulty, you may need a replacement motor unit.
7. Adjust the Travel Limits and Force Settings
✔ If the door starts to open but then reverses, the travel limits may need adjusting.
✔ Look for the limit adjustment screws on the opener unit.
✔ Use a screwdriver to adjust the “up” limit screw slightly.
✔ Test the door to see if it now opens properly.
Misadjusted limits can prevent the door from opening all the way.
How to Manually Open Your Garage Door
If your Craftsman 1 2 Hp Garage Door Opener will not open and you need to get your car out, follow these steps to open it manually:
✔ Step 1: Locate the emergency release cord (usually a red handle).
✔ Step 2: Pull the cord down to disengage the opener.
✔ Step 3: Lift the garage door manually.
✔ Step 4: Once open, secure the door using a clamp or locking mechanism.
After fixing the issue, reconnect the emergency release by pulling the cord again until it clicks back into place.
When to Call a Professional
If you’ve tried all the troubleshooting steps and your Craftsman 1 2 Hp Garage Door Opener still will not open, it may be time to call a professional.
Call a technician if:
✔ The springs are broken (DIY replacement is dangerous).
✔ The motor is damaged or making unusual noises.

✔ The issue persists despite troubleshooting.
Preventive Maintenance Tips
To avoid future problems with your garage door opener, follow these maintenance tips:
✔ Lubricate the tracks, rollers, and hinges every six months.
✔ Check and replace remote batteries yearly.
✔ Inspect the door springs for wear and tear.
✔ Test the safety sensors to ensure they function properly.
