Performed oil cleaning on the furnace. Changed the filter, strainer and nozzle. Took a combustion test. Looked over the humidifier which the customer said there was a leak from in the past. The solenoid opens and closes, with water on and cycling could not see a leak. No issues to report. The ac condenser for the second floor was coming on but the fan motor was not. Went over the wiring and the diagram and even made sure with tech support the wiring was correct. Tested amp draw and incoming voltage drop. The motor must just of been bad from the manufacturer since nothing is wrong with the incoming voltage and the wiring. Ordered a new motor from ral. It will be in tomorrow afternoon. Let the service manager know.
