Furnace
My propane tanks ran empty on my cedar creek 38el. I've refilled and the water heater is now working, but the furnace is not blowing warm. Do I need to re-light a pilot light or is the system automatic. It is a 2017 champagne edition.

If the furnace is further away from the tanks, it may take a little longer for the air to get purged. It may take a couple of attempts & resets to get the furnace going.

Power the furnace off and try again.
As mentioned, it may take more time to purge the line.

There is no pilot light on the furnace. It is automatic lighting on start up. Just to make sure when you select the furnace you should be able to hear a snap, snap, snap sound from the furnace this is the ignitor trying to light the furnace. Just run it a few more times and the system will bleed all the air out and I'm sure it will light off.

Thanks for all the input. It took about ten times but it finally fired up. Thanks all.

Best bet is to not run out of propane completely. Check your tanks often and when 1 goes empty, switch the regulator valve toward the other tank, take the empty one out and get it refilled.

Many of us that have been RVing a while have a fool proof method when removing tanks for refill or simply running out of propane. Open a couple of stove burner knobs, wait about 10 seconds then keep trying the ignitor till they light. This more quickly purges the air out of the lines that always occurs when switching out tanks so your fridge (assuming gas absorption) or furnace will light quicker.

I have an auto switchover regulator on my lp tanks. I check the regulator every morning and if it has switched to my full tank, I locate a place to refill my empty. I check it every day.
My furnace is near my cook stove so if I were to run out of lp, I would bleed the line by lighting the cook stove.
I agree with turning the furnace off for a few seconds if it does not start on the first try. The control board will shut everything down after a couple of failed attempts and you need to reset it to try again.
