Advice on Heater Not Blowing Warm Air

Just to let everyone know. A friend suggested turning the propane off and then on again. It worked! All is good.. Thanks everyone

It is also possible that the sail switch may be stuck.

Are you using the battery or are you using shore power? If you're using the battery and the battery is weak, the fan will not spin fast enough to set the sail switch and thereby not allow the flow of gas.

Tried all those things and still no heat..Anymore suggestions?

My furnace makes three attempts to light, before shutting down with an error condition. Turn it off, wait 10 seconds or so and try again. Let it go through all three attempts and get to error before you switch off and try again. Might take 2 or 3 attempts, or maybe more. Depends on how long the propane line is from the stove/water heater to the furnace.

Ran out of propane so line to furnace has emptied.

Blowing cold air so fan blower is working........just need to cycle furnace a few times so that propane flows to furnace.

Turn t-stat up above inside temp......t-stat should click.
Then turn it down below inside temp.......t-stat should click. Fan blower come on and then 30-90 seconds later furnace should try to ignite (Clicking from furnace)

Repeat a couple of times.

You may need to burp the system due to air in it. Turn on a stove burner and when it stays lit try the furnace again.
