On the roof I discovered that there was not primary voltage to the disconnect for the unit. 1 main breaker box and multiple sub breaker boxes were checked. The three pole breaker for the MAU is located in the closet off of the breakroom and was passing electricity. There were no breakers in the sub panels that were tripped and labeled MAU. There had been extensive electrical work in April. They are going to contact the electricians and see if they can get power to the unit disconnect. Thank you, Jon Tech notes: Cambridge S950//170515F0234 BX52 belt recommended replacing when power returns Info was gathered and forwarded to add the MAU to the maintenance (1x/yr)
