Heater not working

[QueenOwl]

Hi all. On our second trip and it's a bit chilly. Woke up and we are trying to turn the heat on and nothing happens. Propane is on and we hear a "click" then nothing. Any tips?

First, have you ran the stove burners to clear air out of the lines?
Second, are you camping without electric hookups? If so, the furnace requires a minimum amount of 12v battery power to operate. Check the batteries.

Ran burners just to test and they were fine. We have full hook ups. Checked fuse. Same fuse as fridge and that is fine. Very disappointed that this is a brand new trailer 2015.... dealer never did turn on heat since it was 90 degrees....

Well, you will have more problems with the smell when you get it started, it will run you out of the vehicle until the mfgrs oil is all burned off. Should have been done before the PDI at the dealership regardless of the temperature.

Did you not bring electric heaters with you, knowing that you had electric hookups?
It's always advisable to do this, since you save on propane usage.

I guess we didn't think of that... only 2nd trip ever in camper. Using one now....

Start
Thermostat Calls
for Heat
The wall thermostat controls the operation of the furnace by reacting to room
temperature, this allows current to flow through the On/Off switch to the module board.
The module board constantly checks for a minimum 9.5 volts. If there is not 9.5 volts,
the module board will go into a stand by mode until adequate power is supplied. It will
then resume normal operation.
Upon a call from the thermostat, the module board thermostat circuit will go active. The
sail switch circuit is verified as being open. The blower output is energized. Blower
motor starts.
15 Seconds Purge
Cycle
The module board will then verify that the sail switch circuit is closed and motor is up
to speed. If this circuit remains open for 30 seconds after the blower motor starts, the
module board will go into lock out and shut down the blower motor.
The module board checks that the gas valve relay contacts (which are located on the
module board) are open before the ignition sequence starts.
The board has a pre-purge timing circuit of (approximately 15 seconds). This allows the
chamber to purge.
7 Seconds Ignition
Cycle and Flame
Sense
The module board will energize the gas valve and enable the high voltage spark output
to the electrode for 7 seconds of ignition time.
The module board will then check for flame sense to verify successful lighting of the
main burner flame. Sparking will then be terminated and the gas valve and blower
outputs will remain energized.
If ignition is successful the module board will monitor the flame sense, sail switch and
limit switch circuits, and the thermostat inputs during the heating period.
The flame is sensed through the spark wire and electrode. Therefore, it is essential that
the electrode is properly positioned in the burner flame.

furnace needs 9.5 volts to operate. It is a 12 volt power hog. Plug the tt into 110 volt house power to charge battery and provide a solid 12 + volts to the trailer furnace. The information I coped above is from the library tab in the green bar on the top of the page.

Hope this helps Tim

Thanks for this tidbit. Time to go modify my pre-flight checklist.

Cheers,
