Question

Hi

Harry Homeowner here. The patient is a Bryant 310 LP furnace, downflow-mounted, that gives me the 14 code with no circulation fan operation. I cycled the furnace circuit breaker at the house breaker panel, after which the circulation fan ran for awhile but then quit. I noticed that I got the 34 code when the fan was running, but I now have the 14 code.

For what its worth, I replaced the igniter a couple years ago. Back then, the circulation fan would run just fine but it was moving only cold air.

This time I have no fan (except power-up) and no heat. The air filter is clean.

Any particular sequence you can recommend for identifying suspected bad parts?

The inducer fan was running too, after I cycled the breaker per the above.
