STEP 1: Last 2 new Airstreams ( 06 & 07) both required extreme adjustments of thermostat to get operational. I'm saying, back it all the way down, then all the way up, then smack it with the palm of your hand.Keep messing with it until you finally get ignition. Once you reach a comfortable temperature, turn it off. Dont bother trying to set
it expecting it to automatically come back on when the temperature drops a few degrees. That wont happen.
STEP 2: Repeat STEP 1, or replace it with a BETTER unit.
