Furnace Failure FYI
This is just for informational purposes. We've had numerous posts about no heat, furnace malfunctions etc. this winter season as usual. Had an incident last night that I thought might be something to tuck away for those new to RV life and "staying warm".
Yesterday checked my LP regulator to see if my LP tank was empty, showed red and time to refill...because I knew it was very near. Still showed white. Did our thing yesterday evening, used the oven to bake clay while everything operated normally. I figured it had switched, I would verify in the AM and get it filled.
About 3am I and DW woke up cold. Figured the thermostat was set low so waited until the furnace would kick in; it never did. At 4:15 got up and checked and the furnace would not come on. Turned off the thermostat and let it and the furnace reset (audible click). Turned furnace back on with thermostat set to a temp where it should run. It kicked the fan it but burner only clicked then quit. I figured the regulator had failed to switch (it has happened before and it was replaced). Got up this morning and checked; sure enough the regulator showed red on the 1st tank. Slowly moved the selector to the other tank and it showed red as well. Went inside and no joy, the stove would not light. Tapped tanks and one sounded empty, the other not. Went through the routine of turning off the tanks, disconnecting the hoses, reconnect and turn on tanks. It still showed red. After 5-10 seconds the regulator started "buzzing - sort of" then stopped and the window went white. Went inside and the stove along with the furnace was running again. I will wait until it empties this tank and see if it fails again. If so, I will replace (I carry a spare in my spare parts box).
Just thought the experience might be helpful to those new to messing with an RV furnace on that night when something fails and you "wake up cold". Just something to have in the back of your mind if the scenario fits.
