Furnace Will Not Light Up
My brand new 2017 Palomini 180FB has a non-operative suburban furnace.
The blower comes on, the ignitor sparks, but the thing never lights. The first thing I checked was the gas supply. Propane tank was turned on - so that wasn't the problem. The stove top burners right above it work just fine. So gas is getting to the unit.
I turned it on by setting the T-stat. The fan comes on and and within a couple of seconds you can hear the gas valve click open. The ignitor start sparking (I can see it thru the little window), but after a couple of seconds, it quits trying. The unit waits a minute or so and then tries to light up again. Gas valve click, ignitor fires but the burner never lights. It tries to light it 3 times and then gives up -- with just the blower continuing to run.
I read in the furnace FAQ forum that another owner (of a much older trailer) had similar experience and ultimately figured out that the electrode on his ignitor was positioned wrong. That, after he was told by the dealer that his furnace worked fine on the test bench.
Before I drag it to an FR dealer, has anybody seen this before? I am hoping it is some kind of head-slapping rookie (this is my first RV) mistake -- but I don't think so.
Thanks for your help.
