Furnace Inducer Motor Replacement: Draft Diagnosis
If you smell gas or a CO alarm sounds, leave the home and call the gas utility or 911 from outside.
Furnace inducer motor replacement should follow a draft-system diagnosis by an independent heating contractor. The covered Trane UH1/DH1 table lists venting, pressure-switch and inducer possibilities under one draft-pressure error. Record the start sequence so an observed pressure fault does not become an automatic motor replacement.

Three possible paths share the draft-pressure indication
The manual’s three-flash entry names the vent, pressure switch and inducer. A diagnosis must distinguish those paths. Report a silent inducer separately from one that starts and then stops; ask what testing established a motor fault before accepting a motor-specific repair scope.
According to Trane *UH1/*DH1 installation instructions (18-CD29D1-14-EN):
Draft Pressure Error - Possible problems a) Venting problem b) Pressure switch problem c) Inducer problem
