How to Properly Oil a Furnace Blower Motor
The furnace blower motor comes equipped with fans. If these fans become dirty or lacks lubrication, it starts squeaking. This can be easily fixed. Here's how you do the job.
Step 1 – Locating the Oil Ports
Most furnace blower motors come equipped with a self oiling system, but if yours does not have this then you will have to manually lubricate it. Locate the oil ports in the motor. This is where the oil has to be applied.
Step 2 – Buying the Right Lubricant
Buy non-detergent oil that is exclusively made for the furnace blower motor. Do not use an all purpose oil, as it is not apt for this procedure.
Step 3 – Oiling the Furnace Blower Motor
Lubricate the oil ports by applying a few drops on them. Two or three drops would suffice. Do not apply too much oil, as over lubrication can lead to other complications.
Step 4 – Blower Shaft
Blower shafts on the furnace blower motor could have additional oil ports. Locate them and lubricate the ports with the same quantity of oil. It is imperative to lubricate the furnace blower motor once in a year for smooth, hassle free operation.
