I recently had a similar issue. It turned out that the Oasis Node Board was bad. To test this, first you should have an Oasis control pad which is located and stored in bubble wrap and zip tied to the top of your Oasis unit. This isnít used because you have Silverleaf. If you find the control pad, unplug the plug from the Oasis Node Board (silver box with two multi-wire plugs) and plug into the Oasis control pad. Now use this pad to turn on the Oasis AC1/AC2. This will bypass the node board and maybe get your electric side of the Oasis going. If this works you may have a bad node board but Iíd recommend calling Silverleaf to further diagnose.
