deanbam03flyrnes Report post Posted November 26, 2014 I have a 1999 Tradewinds and the front furnace doesn't ignite. I have determined the fault is a bad circuit board. There are after-market boards made by Dinosaur Electronics. Are they a viable option? Share this post Link to post Share on other sites
wolfe10 Report post Posted November 26, 2014 Yes, Dinosaur Electronics does make boards for furnaces. http://www.dinosaurelectronics.com/Ignitor_boards.htm I would contact them with your model number to verify fit. Just wondering, how you determined that it is the board that is bad? Share this post Link to post Share on other sites

wolfe10 Report post Posted November 27, 2014 Dean, Both 12+ VDC to the positive terminal of the furnace and a good ground are REQUIRED. If voltage is low/ground poor, often, the PC board will be "stupid". Same for corrosion and/or loose connections on the PC board. So, it is a good idea to both check with a digital voltmeter between the positive terminal on the PC board and PC board ground and then good chassis ground. If voltage when furnace turned on is 12+ VDC, you have ruled this out. Using a good electrical contact cleaner for the PC board connections would also be in order. After that, note how far into the "furnace run" cycle you get: Fan comes on Gas valve opens/igniter sparks Flame starts/heater starts Heater stays on Share this post Link to post Share on other sites
