Thanks Dave.... but an electric blanket will not do too much here, it would have to be an elexctric sleeping bag!!! I am in Fort Erie Canada directly across from Buffalo NY (I see Buffalo from my window about 1.5 miles form me), and if you have seen the weather on national news it is very cold and a LOT of lake effect snow today.
The furnace has been working pretty much all day today (thank God), and it is about 15 - 20 degrees out there. I think it might have refused to fire once, I don't honestly recall... I'm too tired from waking up every 20 minutes all last night to check on it, so I don't remember if it did have an issue for sure today or not.
I shut off one of the runs for the duct when I reinstalled the furnace but I found another heat register (I didn't know was there), that had something in front of it this afternoon. I was wondering if it is anything like a home furnace that will shut down and not ignite if the heat exchange is getting too hot due to lack of circulation and venting.
I am hoping since I removed the box that was hiding the other duct register and now only having the one in the bed room blocked, that it might work all night.
I am still not sure about the board... it crossed my mind also, but if it was the board it would not likely allow it to run for that long before running into an issue. Something like a cold solder joint will do similar.... but rarely like this (electronics is one of my hobbies).
If it was not getting exactly the correct electrical feed because I also had an oil filled rad heater running on the same circuit, do you think this would be a factor? I know when the electric heater engages I can hear the blower fan drop ever so slightly. Not much, but enough to hear it and the lights also show the difference in power.
The furnace remains running and heating, but I am wondering it at the time of ignition of the furnces, if the other heater is also drawing power if perhaps it is just enough interference to cause an ignition problem. It is not much of a difference in draw on the power.... but as I said the lights dim slightly when it comnes on... so perhaps?
What do you think?
I'll admit this has me stumped... but it staying about 70 degrees in here so far so I'll keep the fingers crossed for the night.
Maybe I'll try to ge tout there tomorrow and do a check on the circuit board.
If you any other might have any other suggestions I am certain willing to try a few things if it keeps up.
