Hello everyone, I am building a house and getting ready to put the floors down but wanted to clean the ducts from dust/debris before I proceed. The air handler is installed with 240 power to it. However, the thermostats are currently not on the wall and just the wires coming out and I have tested the voltage. The red wire has 24volts on it. I wanted to run just the fan so it can blow through all the ductwork so it will alleviate the dust cleanout later. I connected the red and green wire together but the fan didn't run. I have checked the air handler and both disconnect breakers are turned on and the LED inside is on. Is there something that needs to be done to get the fan to just run? Does the thermostats need to be installed before i can run the fan? It seems like the handler is getting power to send to the thermostat since it has 24 volts but the fan is not turning on..Any help would be appreciated. Thanks!
