Older stock, different problems
Westerville's median home was built in 1982. About 26% of homes date from the 1970s and 18% from the 1980s, and some 46% were built before 1980. About 72% are owner-occupied. The city's 2025 population estimate was 38,165, about 9,100 of them in the Delaware County part and the rest in Franklin County.
In a house that age, the garage door may be on its second or third opener, or still running one that predates today's safety rules. Federal standards since 1993 require openers to reverse within two seconds of contact and to have a backup safety system such as photo eyes. CPSC advises testing that reversal monthly.
If your door doesn't stop and reverse when something is in its way, or the sensors are missing, read about safety sensor and auto-reverse repair and stop using the opener until it's checked.
