that serves three purposes:
• Disengages the motor start winding (M6).
• Engages the motor run winding (M5).
• Closes the circuit contacts for the heat source.
The switch is an internal component of the motor
and cannot be replaced separately.
The blower wheel is held to the motor shaft utilizing
a blower wheel clamp.
Motor resistance values:
Start winding = approximately 5 Ω
Run winding = approximately 4 Ω
