Heater Cores and Blower Fans

Warmth from a heater is generated through the conversion of electrical energy into heat energy by the heating element within the heater. This heat energy is then transferred to the surrounding air through convection, where the air molecules near the heater absorb the heat and become less dense, causing them to rise and displace cooler air. This process creates a convection current that circulates the warm air throughout the room, eventually reaching you and providing a sense of warmth.

Remove the covering under the glove box. Disconnect the power to the blower. The blower motor is fastened to the ductwork with 3 screws.

The shining cover on the coils of a room heater is likely a nickel or chrome plating used for corrosion resistance and durability. It also enhances heat conduction and distribution, thereby increasing the efficiency of the heater. Additionally, the shiny surface may aid in reflecting heat back into the room rather than absorbing it.

The hot wire is typically connected to the smaller prong on the fan motor plug. However, it's always safer to use a voltage tester to determine which prong has power before working on any electrical connections.

A fan designed with a low-speed setting will reduce noise while still providing slight airflow. This can create a more peaceful environment without the distraction of a noisy fan.
