Furnace Blower Motor Replacement: Motor or Control
If you smell gas or a CO alarm sounds, leave the home and call the gas utility or 911 from outside.
Furnace blower motor replacement needs a diagnosis of the installed motor and control system. Lennox SLP99DFV diagnostics separate blower communication failure from a blower unable to start. Give an independent heating contractor the exact model and code so communication, mechanical and motor concerns remain separate service questions.

Communication loss and an unable-to-start blower differ
E201 concerns communication with the blower; E292 describes an unable-to-start motor and names a seized bearing or stuck wheel. Ask the contractor which condition is present. The distinction helps define whether the proposed work concerns communication, a mechanical obstruction or the motor assembly.
According to Lennox SLP99DFV installation instructions (100002a):
Indoor blower communication failure - Unable to communicate with blower motor. Indoor blower communication failure including power outage.
Indoor blower motor unable to start - Seized bearings, stuck wheel, etc. Indoor blower motor unable to start (seized bearing, stuck wheel, etc), replace motor or wheel if assembly does not operate or meet performance.
