Appreciate all the opinions and advice.
Whatever I do it needs to get done very soon. The furnace is working intermittently, yesterday I turned it up and pretty quickly the house was filled with a sort of hot metal smell so I turned it off. Turned it on again last night and nothing - no fan, no gas flame. Turning on the fan alone produced nothing, it wasn't going, so I left it off overnight. Electric blankets rule.
Fortunately it's not really cold cold here yet, lows in the upper 30's overnight and highs in the 50's, but the house
was a bit chilly stepping out of the shower this morning. Just started the furnace up a minute ago to see what happens and it appears normal, fan is turning and the gas flame is normal. I'll let it run a while to get the house up to a tropical 65 or so and shut it down again.
