1.
A contractor is preparing to install a sectional overhead garage door
and discovers the opening is not square. What should be done first?
A. Install the door anyway and adjust the tracks later
B. Correct or properly account for the opening conditions before
installation
C. Increase spring tension to compensate for the uneven opening
D. Trim the door panels until they fit the opening
Answer: B
Rationale: An improperly prepared opening can cause binding, uneven
operation, premature component wear, and unsafe door movement
after installation.
2.
During an inspection, a technician notices that an overhead door closes
rapidly after the operator reverses direction. Which component should
receive immediate attention?
A. Door weather seal
B. Counterbalance system
,C. Exterior door finish
D. Decorative hardware
Answer: B
Rationale: The counterbalance system helps control door weight and
movement, so abnormal closing speed can indicate a dangerous
mechanical problem.
3.
A sectional door is difficult to lift manually even though the panels and
tracks appear properly aligned. What condition is most likely
responsible?
A. Excessive spring imbalance or incorrect spring adjustment
B. Incorrect weatherstripping color
C. Insufficient door insulation
D. Loose exterior trim
Answer: A
Rationale: A properly balanced overhead door should move smoothly
by hand without requiring excessive lifting force or creating
uncontrolled movement.
4.
A technician must replace a broken torsion spring on a commercial
overhead door. Which practice provides the safest approach?
,A. Remove the spring without securing the shaft
B. Use appropriate procedures and tools designed for controlled spring
handling
C. Increase spring tension before removing the broken spring
D. Cut the spring while standing directly underneath it
Answer: B
Rationale: Torsion springs store substantial energy, requiring proper
procedures, specialized tools, and controlled handling to prevent
serious injury.
5.
An overhead door repeatedly comes off its vertical track during normal
operation. What should the contractor investigate before replacing
major components?
A. Track alignment, rollers, fasteners, and door movement
B. Paint thickness on the door panels
C. Interior lighting levels
D. Building landscaping
Answer: A
Rationale: Repeated derailment commonly results from alignment,
roller, fastening, or structural issues that should be identified before
replacing components.
6.
, A customer asks a contractor to install an overhead door operator
without providing electrical power at the installation location. What
should the contractor do?
A. Connect the operator to any nearby lighting circuit
B. Discuss the required electrical provisions with the appropriate
qualified professional
C. Use an extension cord permanently as the power source
D. Eliminate required safety devices
Answer: B
Rationale: Permanent electrical installations must comply with
applicable requirements and should be performed by appropriately
qualified personnel.
7.
Why is proper track alignment especially important when installing a
sectional overhead door?
A. It improves paint adhesion
B. It reduces binding and allows rollers to travel correctly
C. It eliminates the need for springs
D. It increases the door's decorative appearance
Answer: B
Rationale: Correctly aligned tracks allow rollers to move smoothly while
reducing friction, noise, wear, and the possibility of derailment.
