Separate the two fans
The small combustion fan and the large room-air blower have different jobs. Tell the service company which fan you believe ran and whether air came from the registers. An observation of no room airflow is useful; it does not establish the blower motor is the failed component.
Do not open the unit to verify flames or fan movement. Report what you already saw and heard. Add recent repairs, safely visible fault information, and whether the shutdown recurred.
We recommend a diagnostic visit covering the blower and the protective shutdown together. Replacing a part without explaining the overheating-related behavior leaves too much unresolved.
What the professional needs to establish
Ask why the blower did not operate when required and what testing supports that answer. Depending on the equipment, the assessment may involve the motor, its control, electrical supply, settings, and the air path. Those checks belong to the technician.
Ask whether a protective control stopped heating and whether it was responding correctly. Do not accept bypassing that control as a way to keep heat running. A protective shutdown is information to investigate, not an obstacle to remove.
Request the applicable manufacturer startup and operating checks. The technician should explain whether any damage or additional condition needs attention before the furnace is used again.
Judge completion by operation, not a new part
Ask for the confirmed finding, the repair scope, total price, and remaining uncertainties. After repair, request confirmation that heating and airflow were checked through the proper sequence and that the unit meets its operating requirements.
If the home is cooling, confirm repair timing and an update contact. Plan another warm place if the household cannot remain suitable while waiting. Do not let the need for heat lead to repeated firing without verified airflow.
Your next action is to stop the ordinary heat request when safe and report “burners start, no main airflow, then shutdown” for prompt professional help. That summary communicates the concern without turning it into a guessed motor replacement.
