What is the DC voltage of a Dometic furnace blower?
Get your meter and check it to be sure that the charging device is putting out the 13.7 to 14.2 VDC that these put out when working properly. That would be to the fuse block and the batteries. Then check the DC voltage out of the load center and see what that is.
Is the ignitor tip on a Dometic furnace reliable?
Gary, those ignition systems are “fairly” reliable. Its basically a step up HV coil/transformer that receives pulses and the ignitor tip sparking to light the gas. I’ve encountered more ignitor tip failures (cracks, carbon traces, shorts, mis adjustments) or control board failures then the HV ignitor coil/transformer itself.
How can I tell if my furnace igniter switch is working?
Look under your furnace to see if it’s lit. If not, you can use a long match to try and carefully light it again. If that does not work then you have a bigger problem. With an electronic furnace igniter switch, your furnace is safer and does not use the small amount of gas that a furnace with a pilot light does.

What to do if your Dometic furnace runs out of propane?
You may experience this if you run completely out of propane as well. When you first change bottles or if you have had the propane turned off for an extended period, I always start by lighting the stovetop burners, first one until it burns steady, then all of them for a couple of minutes.
