Propane bottles full, and turned on SLOWLY. Too quickly and the safety shutdown engages. Light a stove burner to help get propane flowing, Set the thermostat to the temperature you want and turn it on. The blower will come on to purge the furnace before the ignition sequence begins. It'll cycle three times before going into lockdown. If it didn't fire up, turn the thermostat to off, back on, and it'll try three more times. Most times it'll take two or three tries before it gets enough propane to stay lit.

If that doesn't work, it's time to check fuses and make sure the battery isn't weak.

Clarify a bit for us. Does not even start up? Won't light (clicking but no ignition, ignites and goes out, ignites multiple times and won't catch and continue? All or any of these might give us some place to start with suggestions.

In addition to all the above, thermostat set to "Auto" instead of "Heat", and the fan setting not on "High" setting. Reset switch on the furnace itself needs to be reset.

To be clear you are saying the blower never kicks on at all?

There has to be a way you can access the reset switch on the top left front of the furnace. Where is your furnace located?

Can you put up a pic of your thermostat?
Not sure which one you have.

Did your furnace work before you replaced it?
I see there are three versions of the dometic touchscreen ones.

Watch a couple youtubes on furnace maintenance if you can. Plus, is you voltage up to 12 volts or above. Several posts available on the search bar above.

Mine is also under the kitchen countertop. On mine, there is a large louvered wood air intake vent on the side of the kitchen cabinet. If I take out the four screws holding the vent in place, I can pull the vent out of the cabinet sidewall. With the vent removed, I can easily reach the furnace toggle switch to turn it off, then back on (sort of like resetting an electric circuit breaker). Or, you may have to remove the drawers to expose the furnace switch.

If I run out of propane, I have to reset mine. Perhaps your furnace thinks you've run out of propane and needs to be reset. Hope this helps!
