air conditioner issue

[ndennis47]

Hello,
I was wondering if I could get some troubleshooting help on an air conditioning issue from you all. Everything worked fine last summer, went to turn it on this year, and I can hear the compressor turn on, however the fan does not blow any air. Any suggestions, or has anyone ever had this issue? Thanks in advance.

Could be a couple of things....First off I would check your fan motor, break out the multimeter and do a couple of ohm checks across the wires. You can find some manuals online for whatever model you have and it should have information on what ohms your motor should read. Next thing I would check is you have a fan Capacitor inside the unit on your roof, that might be bad.....Good Luck

Wall Thermostat or built in?
If wall t-stat set the fan to ON and see if it runs. If it does then switch it to AUTO. If it doesn't run then it could be there's something keeping the switch from actually making contact.
I had a customer a few years back that wallpapered the wall where the t-stat was mounted. A drop of the glue landed perfectly in the contact switch. Unit ran fine in cooling but when he switched it over to heat the glue had dried and insulated the contact.
With all the vibrations in a trailer there's the possiblity the fan wire may have come loose or broke. Remove the t-stat and check out the wiring.

if it sat a long time unused i would kill power and remove the roof cover and make sure the fan inst blocked by a nest of some sorts,
we have barn swallows here that will build a new nest in a weekend when we are gone

Thanks everyone for the ideas and assistance, ended up being the motor starter capacitor, everything is working just fine now. Thanks Again!!!
