Blower Motor Resistor: Description and Operation
Blower Motor Thermal Limiter
The thermal limiter, used in the heater blower motor switch resistor:
-
serves as a temperature protecting fuse.
-
it is located a predetermined distance away from the resistor coils and in series with the coil circuit.
-
it will open the resistor coil circuit when temperature of the thermal limiter reaches 121°C (250°F) interrupting blower motor operation in all
speeds except HI.
-
the spring contacts that separate when the wax softens, opening the heater blower motor switch resistor circuit.
-
requires replacement of the entire heater blower motor switch resistor because spring contacts cannot be closed again.
