I have a 2002mobile home this summer my circuit board went bad so I found another one but now when I went to turn my heat on the pilot comes on for about 3seconds then shuts off and then the furnace runs threw it's cycle and does it again I looked for a flame senser but couldn't find one is the board I got possibly bad or what but its starting to get very cold at night and can't afford to have someone come out

Quite honestly it can be that or any number of other things... I recommend finding the money somehow and getting someone out there that knows what they are doing...

Ok thanks

If you don't you can literally be throwing money in all the wrong places... and it might end up being something very simple and very cheap.
