    Could be your high temp limit switch is opening up. This device is part of the safety mechanism for your furnace. This means the temp is too high inside the combustion chamber. I had a similar problem with my Bryant Plus 80. See this thread: https://www.askmehelpdesk.com/heatin...at-293962.html

    My high temp switch eventually gave up altogether and opened up and stayed that way causing me to have to replace it. I feel the original cause was a dirty air filter. I'm good now with the replacement switch AND a clean filter.
