Furnace not lighting up
We have a 2019 3120RL and recently the furnace stopped working. When I turn it on via the Dometic thermostat, the fan comes on as it should, but the furnace does not light. I reset the thermostat to factory settings, and that didn't solve the problem. The fan comes on, runs for a bit, then shuts off, then on again, etc. Yesterday it worked fine. Today the above. Any ideas?
