Garage Door Test Protocol

Operating door(s) with absent, misaligned, or damaged components can cause serious injury or death. Do not use the door until a trained door systems technician replaces or repairs. Garage door testing performed during this inspection in NO way ensures future safe operation of any of the units involved. The homeowner will be responsible to test all units present monthly by this protocol to ensure future safe operation. Contact a trained door systems technician for further information or whenever any repairs are required. Do not attempt repairs yourself unless you are qualified in garage door and or opener installation!

PASS FAIL 1. Door Operation & Spring Inspection

Check all fasteners, hardware, and other components for presence and proper attachment.

Begin with door fully closed. Pull manual release to disconnect door from operator. Manually lift door up. Door should move freely and open or close with about 20-lbs. force. If it is difficult to open or close door, inspect for damage or a broken spring. If there is a broken spring, it should be replaced by a trained door systems technician before proceeding further with inspection.

PASS FAIL 2. Counterbalance Spring Containment

Door counterbalance springs will break over time with normal usage. Therefore, counterbalance springs and their attachment components are to be restrained either externally (via a tube that contains spring[s]) or internally (via a cable or shaft). Verify spring containment is present.

PASS FAIL 3. Wall Station Push Button

A garage door with an operator should have at least one working push button wall control. Push button to ensure that it is operating. A push button wall control must be mounted in clear view of door and away from all moving parts. It must be high enough to be out of the reach of small children (at least 5 feet above standing surface).

PASS FAIL 4. Photoelectric Eyes Location

Photoelectric eyes, if present, must be mounted no higher than 6 inches above floor to detect an obstruction in path of door. Critical: Follow manufacture instructions for your specific opener.

PASS FAIL 5. Contact Reversal Test with 2 x 4 obstruction

Begin with door fully open. Under center of door, place a 1 1/2” thick piece of wood (like a 2x4) flat on floor. Electric operator should reverse door upon hitting the wood. Maintain physical contact during this test with electronic controls to manually reverse if unit fails to self-reverse in order to avoid damaging the door or opener.

PASS FAIL 6. Non-Contact Reversal Test

Conduct this test if photoelectric eyes are used, and begin with door fully open. Standing just outside path of door, using a transmitter, push button to close door. Wave an object in path of photoelectric eye beam as door is closing. Door must reverse and return to the fully open position.
