Hi, im new here and hope someone can help. my dumbwaiter is not working in a vacation home which isnt frequently used.we believe it happened after a power outage. the buttons are not illuminated, but my handyman says there is power coming in. he says the fuses are good and the circuit breaker is also good. he thinks it might be either a blown a transformer, a fuse he cant find or some sort of surge protector needing to be rest, but isnt familiar with dumbwaiters and doesnt know where to start. the builder that installed it is out of business and the company ,inclinator co , wants to charge $340 just to come to the house. any help would be greatly appreciated. thanks
