A garage door that won’t open or close is almost always fixable without calling a technician.
What Causes a Stuck Garage Door? Dead batteries in the remote, misaligned sensors, or a broken spring.
Step 1: Check the remote batteries first — replace them.
Step 2: Check the sensors at the bottom of the door — clean them with a dry cloth.
Step 3: Make sure nothing is blocking the sensor path.
Step 4: Lubricate the tracks and rollers with garage door lubricant.
Step 5: If the spring is broken — call a professional. Springs are dangerous to replace.
