Bolts fell out of door. Added larger lags and tightened all bolts and nuts on wooden sectional garage door. Also saw that header 2x4 had pulled from the wall causing opener to bounce during operation. Added new lags and reattached wood to give opener needed support. Included tune up and lubrications service. Older Genie garage door opener does not have safety sensors or cover. Circuit board is exposed and dangerous if touched. Recommend chain drive Liftmaster unit which is better suited for current wooden garage door.
