garage door operators may fail to operate for any of the following reasons except
improperly installed
the auto reverse sensitivity is set too low
poor door adjustment
the gfci receptacle has tripped
poor operator adjustment or maintenance

Explanation:

Question 1

Basement walkouts actually reduce frost depth around the house as they expose soil to cold air. Railings are important for safety around basement walkouts and do not obstruct escape. Lowering foundations/footings can help with frost - related issues, cracks can indicate frost heave, and walkouts can be water - entry points.

Improper installation, poor door/operator adjustment or maintenance, and a tripped GFCI receptacle can cause garage door operator failures. Auto - reverse sensitivity being set too low is not a reason for the operator to fail to operate; it is more related to safety functionality when the door encounters an obstacle.

Answer:

basement walkouts allow greater frost depth around the house, railings should not be provided around the top of basement walkouts for fear of obstructing escape
