Furnace

[michael.mcilrath]

Hello everyone. Woke up to the camper being 59 inside and noticed the furnace didn’t come on. I checked the fuse and it’s okay. I turned the furnace off and back on and it started but doesn’t blow hot air and shuts it’s self back off again and I have to reset it and the process starts all over.

Propane tanks empty or off? Regulator failure?

Do you hear the igniter clicking when it starts?

Are you on battery or shore power? If on battery do you know what the voltage is?

Sounds like you've run out of propane or have a low battery(ies) and your furnace went into lock-out mode. That's why you had to turn it off, then back on.

Does all three stove burners light and operate on high at the same time?

Do you have two tanks?

Do you have BOTH valves open?

Do you have an auto-change over regulator?

When you first turn on the furnace do you hear the DSI spark ignition clicking?

Are you on shore power?

What is the state of charge of your battery(ies)

Thank you for all the replies. I will check the gas when I get home and wasn’t aware it did run in the gas. I am on shore power but can’t answer if it runs on both like my fridge does. I do have two tanks with a switch over and all that will be checked at lunch. Thank you again!

The furnace burns LP (propane) only to make heat.

Some (not all) A/C units have an electric element (heat strip) or utilize a heat pump system to make supplemental heat but the furnace is strictly propane for heat AND 12v to operate the blower and the controls.

The furnace (and the R/V) is built this way so if you have no shore power (boondocking) you are still able to have heat. (provided you don't run out of LP or battery power)

Many folks use an electric space heater to supplement the furnace when shore power is available.

Your furnace is one of the largest propane users in your R/V.
In cooler/cold weather it can deplete a 20# tank quickly.

Your furnace doesn't run on 120v AC shore power.
The electronics and fan run on 12v DC power and it uses propane to heat.
Your dealer must have done a poor PDI/walkthrough to not have explained that to you.

Thank you all for the replies and yes, I went home and the auto value never switched to the new gas tank. This is my first winter using the heat and again thank you all.
