I have an otis hydraulic in my two story building that was installed in 1998. I own the engineering firm on the second floor and the lift has not seen any real use. Occasional file transfers from one floor to the next. We use it to store blueprints mostly. Anyhow so last week a squirl fried itself on a power line outside and the whole building lost power. After the fried squirl was removed by city power the electric was restored and all was back to normal, except the lift doors would not open when i went to retrieve some prints. Made a call to our local otis and he was able to upen the doors but said to get the lift working again it was going to cost 2k. I purchased and installed this lift for 12k, what could be causing the problem? He said the control was bad. Control reads flt on board. It is a 211. Parts and labor 2k not including 300 service. Advice is asked for. Thank you.
