Hello Folks -

My x20e is less than 1 yr old. The furnace has run fine since day 1. I went out today to check on the systems. The furnace would not start not even the blower. Checked propane at stove and sure enough out on tank 1. Flipped to tank 2, back to the stove, bled the line and got a flame on all burners. Tried the furnace - nothing.

Checked all fuses - fine. Pop off thermostat (digital Honeywell mod) and test wires with multimeter - power detected. Pop off front of furnace and access DSI board. Multimeter shows power coming onto red wire feeding board but that's it. Cross power feed line to blower line and blower starts up. Red LED on board only goes on when I crossed the lines. Off/Reset sail switch works as no power to feed line on board when off. Is this enough info to assume the board is bad and to get a new one??

Check the battery, if you have a meter check to see how many volts there are

I tried it with just AC power then replaced the battery so it was fully charged.

The best way i have found to Quick check the battery I use here is to measure the voltage at the battery terminal first without shore power connected. If the battery is fully charged it should read around 12.6VDC. Then go plug the trailer shore power cable into 120VAC and the converter/charger should then apply around 13.6VDC at the battery terminals. If you see this increase in DC voltage then you can assume all of the hidden fuses or circuit breaker between the 12VDC Power Distribution Panel where all of the 12VDC plug in fuses are located and the battery is working fine. If you don't see the 13.6VDC at the battery terminals then something is not working properly..

I think the circuit boards for the furnace are pretty robust as you hardly ever hear of one failing on here. Its seems to always be something else failed - sail switch or hidden fuses somewhere. My furnace blower seems to always come on for a couple of minutes when turned on by the thermostat. Then you can hear the clicking noise of the ignition trying to fire up the furnace. After three clicks (I think it is) and it doesnt fire the furnace then it needs reset by turning off the thermostat and back on again. When it finally fires after several clicks it will shoot fire out of the outside heat vent five or six inches long with a loud WHOOOOMP... Scares me and my dog.... I can't drag my dog by that heat vent after that for a few days hehe... I guess he thinks it is a monster fire dragon or something...
