I have a Coleman furnace with a S1-7990-319P control board. The blower started turning on/off intermintantly until cooling setpoint has been reached. I have tried different t-stats, jumpering limits, and am on my 2nd replacement board they all act the same. The relay on board is clicking on/off. Is this a factory defect? I'm running out of options.

Hi,

The 7990-320P is an upgrade to that board that you may wish to consider. Or you can call Mark after Monday at 605-229-2627 and get info on sending board to him and getting the relay replaced on the board only.


Thanks,
Robert
