The refer needs 12 volts DC, battery power, along with the propane in order for it to work. Make sure the propane is ON at the tank and that you light the stove burner first and let it burn until it burns steady, this will get the air out of the line, Then make sure the battery is fully charged, 12.6 volts, and that the battery disconnect switch is in the ON position then turn the refer to GAS and you should hear the igniter try and light the refer. It might be best to disconnect from shore power while doing this test so you are just testing the gas part of the refer. If you have the refer on AUTO and plugged into shore power, it will automatically switch to 120 V AC and you wont hear any noise indicating that it is working because it is silent in operating on shore power. Give it a try and let us know what happens.
