Furnace won't light.

I have a Rockwood 2905ss. Has a Domitec furnace. Last year one night one of my propane tanks ran empty and it automatically switched over like it should. Problem is ever since then I can't get my furnace to light. It tries but stops after 30sec or so. What am I doing wrong?

Seems like you are not getting propane to it. Where in Ontario are you?

Ottawa valley. It sounds like that to me also but for the life of me I can't figure out why. Stove will light, hot water heater is fine.

Air in lines, keep cycling it, it should come on. See if you can purge the line. Disconnect battery, or flip the disconnect switch to reset board in furnace and keep trying. Keep us posted. For moments like this i carry with me an electric (120v) heater. Not warm here in Wasaga Beach either

Thankfully I'm not camping now. But all of that has been done. Battery has been disconnected and now back on. I have cycled it more times than I can count.

Was that your first time trying to start it this year? Are you handy?

Make sure propane is on, turn fan setting on thermostat to AUTO. Adjust thermostat to desired temp, should go on.
Might want to fire up stove, that will ensure you have gas in lines

Light a burner on your stove and allow it to burn for 3-4 mins to clear the air from the lines. Then try the suggestions below. The fan should come on first(Safety feature), then you should hear a clicking as the furnace tries to light. After 3-4 failed attempts, the safety feature will kick in and you will have to shut the furnace off to reset the control board.

Turned out to be a motherboard issue. Warranty replaced.
