Yes there is one at the bottom of your dash under the console drawers. To enable that one there is a rocker switch on the dash. I believe mine is labeled “front fan” and has Hi/Lo/Off.
There should also be some louvered openings on the kitchen cabinets where heat will flow from.
Make sure “zone 1” is set to “furn” on the dometic thermostat because zone1 is the front and zone 3 is the rear (zone 2 isn’t used when running Oasis).
Check your “zone board” down in the basement near the Oasis burner for any red lights which indicate a failed pump or other component.
Dutch Star Don has a great write-up in the sticky threads at the top of the forum about Newmar Info about the whole operation of the Oasis for hot water and heat.
