AC not blowing air

[nick11]

Hi everybody just bought an 05 Rockwood 8243s - the AC comes on and it sound like the compressor is working but no air blows out . What should I check first? I do not have the original owners manual.
Thank you
Brandon

Firstly, welcome to FRF - drop into the Welcome Mat.

Re your AC issue, no flow = no blower. Power to the blower motor? Blower motor is pooched? Access the blower and work your way back. It may be as simple as a bad connection on the blower.

Could be a "DIRT DOBBER NEST" that has the blower motor locked. I had this to happen to a older RV!. Check blower squrirrel cage and fan blade. You will have to remove bottom of A/C and top cover!



Good luck!

If not one of those, (though the motor being frozen for some reason is high on my list), there is a starting capacitor for the blower motor that could also be bad.

While you have the roof cover off, write down the make and model.
Someone here will post your manual.

With power off pull the cover to the ac unit and spin the fan motor by hand, look for something obstructing the fan like wasp/mud dober nest. Should be a dual shaft motor, in other words a shaft coming out each side of the fan motor. If the the fan is hard to spin by hand, check to see if there are any little plastic or rubber oil plugs on the motor. IF so pull the plugs and put some 3in1 oil or Zoom oil in the little ports and replace the plugs. Have someone start the ac while you watch the fan and see if trys to start. If it looks like it is trying to start, but wont check the capacitor see if the top of the capacitor is buldged out. If the top of the capacitor is buldged out it needs to be replaced.
