A/C not working
Went to use the A/C this weekend for the first time this year, and couldn't get it to work. It sounded like the compressor was working, but not the fan. Attempts to get just the fan to work failed as well. With the thermostat turned all the way up, and the fan switch on ON, and the FAN SPEED set to HI and switch set to COOL, I could hear a slight hum, and the lights dimmed slightly, but no fan. Any ideas? Thanks in advance for any replies.

Sounds like you may have a nest inside the cover or a bearing stuck.
Pull the top cover off and try to turn the blades.

We have had this problem twice, the last time a few days ago. My husband fixed it by removing the A/C cover and using WD40 then giving the fan a nudge and it works just fine. Diana

Wait...which fan? There is a Fan up top for the condensor...this one moves air over outdoor coil to allow condensation of freon (release heat). The one inside the rig is behind the return air panel, is a squirrel cage and is the one that moves the air over the evaporator coil to the outlet ducts. If you have no movement of air your problem is with this one.

This is the fan that's not working. Is it easy to get to? I'm thinking it might just need some oil. Thanks for the reply.

STOP Please turn off all power before you open the fan area. Thanks and be safe.

You could have a "dirt dobber" mud nest on either. I had the problem in the past on each at different times. Remove the inside cover first, you should be able to reach the fan in question to see if it can be turned. You may still need to work from the top as well
Good luck!

I had a similar problem and contacted Dometic, it seems they had a bad batch of fan motors, they paid to have mine replaced.

So, what's the easiest way to get to the fan? I can't see how the grill comes off from the inside. Thanks.

Frank,
on my AC the return-air-vent grill includes plastic tabs on one side which are pressed inward to release. You can then just remove the grill. It is just as easy to replace it. Yours may be different, but this is how mine works.

Thanks for the reply. I found that, and had it apart, but that doesn't get me to the fan. It must be accessed from the top. Probably have to take the big white cover off from the roof?
