Quick answer
The safest way to identify the furnace type is from the equipment label, visible fuel connection and system documentation—not by guessing from the thermostat. Do not remove service panels just to identify it.
What the symptom can point to
Record what happens before, during and after a heating cycle. Whether the system starts, reaches normal heat, shuts down early, runs continuously or fails to reach setpoint helps narrow the branch without assuming one failed part.

How the HouseIt tool makes this more specific
The tool asks only for facts that can change the branch or result. Unknown answers stay unknown, and the result should become more cautious rather than inventing precision.
