A/C fan cutting out

New Sunseeker with a Dometic 15K air conditioner. After running for about 5 minutes the fan cuts out for about 5 seconds but the compressor will stay running. It does this several times and then it acts normal. During this time the incoming voltage is probably marginal at about 110v. Have only been out once with it in hot weather so have not had a chance to characterize it further. Contacted Dometic and got a generic statement back that "when operating at anything other than 120v it may not act normal". Anyone else experience the same?

If you have the fan on auto and the temperature is within 5 degrees of the requested temperature the fan will shift from high to low then back to high again if not keeping up.

You can try running it on hi instead of auto and if it still does it most likely there is something wrong

That's normal. Mine has done the same thing since I bought it new. Will cycle from high to low.

Murphy, we ran across this info, you may already know. When cycling through the t-stat.... Fan, AC, Heat, Furnace. etc. stop on fan, then use the up, down buttons to select auto, high, low.
