Furnace Blower Motor Oil Ports

Lubricate the oil ports by applying a few drops on them.

Furnace blower motor oil ports.

Do not apply too much oil as over lubrication can lead to other complications. Cleanout and observation ports as shown in figure 12 2 an oil furnace typically is provided with one or two cleanout ports to allow access to the heat exchanger for cleaning soot removal. They may have red or other colored plastic caps that cover them. Two or three drops will suffice.

If the motor has oil ports it should be lubricated annually. Unless the motor has oil ports at either end they are sealed bearings and can t be oiled. Blower shafts on the furnace blower motor could have additional oil ports. This video is part of the heating and cooling series of training videos made to accompany my.

Or send us some sharp photos of all sides of the motor and we ll comment further. It is imperative to lubricate the furnace blower motor once in a year for smooth hassle free operation. I show where the oilers are on the blower motor of the furnace. If the blower shaft has oil ports it too should be lubricated annually following the same procedure.

They should be clearly marked with labels. If you have a serviceable blower motor it has one or two oil ports. Locate them and lubricate the ports with the same quantity of oil. There are two lubrication points on most draft inducer blowers although there are sealed motors that do not require lubrication.

An oil port is on both sides of the motor. Lubricating a furnace draft inducer blower also includes the motor shaft where it enters the bearing collar of the blower wheel. Going by past experience inducer motors rarely if ever have oil ports. Step 2 inspect the blower motor for the oil ports which are located directly on the side and are sticking upwards.

Visually locate the oil ports on the motor and shaft. Depending on the manufacturer there might be two or three oil ports. Below we illustrate three electric motors all happening to be found in heating furnace blower compartments. The observation port allows monitoring of the inside of the heat exchanger during the operation of the furnace.

Oiling the furnace blower motor. I couldn t tell by the picture.
