Capacitors by Treat’s Heating & Cooling 

Furnaces use a lot of energy to function properly.  Gas that enters a furnace is ignited by a pilot light or auto start in newer furnaces.  The burners heat the air going into the furnace and the blower blows the hot air through the duct system of your home.  Extra energy is required to power the blower so it is connected to a capacitor that works similar to a battery.

Capacitors store extra energy needed to kick the blower on.  A faulty capacitor may prevent the blower from functioning at all.  Before Treat’s Heating & Cooling checks the capacitor, we will make sure the fuse controlling the furnace is flipped to the on position.  If the furnace is receiving power the thermostat can be turned up to see whether the blower motor starts in the next few minutes.  If not, the capacitor or blower motor isn’t functioning properly.

Faulty capacitors will not be able to hold the charge necessary to run the blower motor properly.  This will cause the motor to run slowly, causing excess heat.  Excessive heat in the motor can cause the motor to malfunction.  If you notice your furnace motor cycles frequently, the capacitor should be tested.
