Indoor unit fan blows, then stops etc. every 1-2 minutes

1. Fan failure
2. Control board failure

Clogged air filter or a loose belt between the fan motor and fan wheel will cause a frost up.

The Best place I have found that has quite a few at reasonable prices plus knowledgable store personell that will guide you to what your needs are..and their warenty policy at Lowes Stores.is excellent....give them a try and good luck.

Lmfao at Ken, dude this is a single phase 120 vac motor. You can close your eyes and pick one there is no switching of wires to the motor. YOur hot can go to which ever and your neutral can go to which ever. DOES NOT MATTER :-P don’t reply unless you know blow horn. But just a heads up you can Reverse rotation very easy...

If it were a car I'd say something to do with the belt. Maybe check that out.

The fan needs oiling (except for the Fresh Air, which has sealed bearings and no removable front grid). I need to know which model you have to help you reach the fan shaft. However, if you're handy, you can figure it out. Remove the front grid (if there is one on your model) and pull off the fan blades. Use a light household oil (sewing machine, hair clipper, 3-in-1) to drip down the shaft as you turn it manually. This should take care of the problem.
If not, and if you need more extensive repairs or rebuilding, call Vollara (new name for EcoQuest) customer service at 1-800-989-2299 and use 16618 as your dealer referral number.

best is if you have an air compressor and blow it out, if not, a paintbrush and vacuum will do. remove grill/cover if you have to. make sure unit is un plugged.

Have you cleaned the unit good and made sure that there is nothing crossing the grid wires? It sounds as if it is cutting off and resetting for some reason. Mine runs continuously. I take an air compressor and blow mine out every time I clean it. Also, on some models, you have to hold the on button down for several seconds to reset it after cleaning. Hope this helps.

There may be a leak. You might try shutting it down and taking a look inside. On the other end, there may be something wrong with your components inside. The compressor outside is to provide coolant. Inside, the fans actually cool the air. Make sure all doors are on the blower downstairs, and if all else fails, call a technician. Good luck!
