The only oil ports that you will need to worry about will be on the the indoor blower motor. Depending on the model version, you might have sealed bearings or oilable bearings. Best way to find out is to take the door off where the blower is. Make sure the unit is unplugged ao locked out please. You do not want anyone turning the fan on when your hands are inside the unit at this point. Then get a mirror and follow the outside edge of the motor all the way around. Usually you will have aq red or yellow plug where you oil the bearings, but they might have fallen out over time. Also look for little holes anywhere around the end of the casing. These are the oil points. If you do find them, make sure you use a light oil, something like 3 in one oil. Only use about 5 or 6 drops. A little goes a long way. If you find them on the outside where it's more visible, they will be on the inside where the squirrel cage is, so you'll need a flashlight and a mirror to locate the inner bearings. If they are not on the outside, you have sealed bearing and you don't need to worry about it.

Hit the side of the furnace. Some times there's a sensor inside that gets locked up from a dirty filter.

Furnace computer won't let furnace light


What is the model number? I have an SLP98 (installed on 11/29/2011).... and if I take the cover off the front of the furnace the panel that has the fancy "Lennox" badge on it) you will see two clear round windows about the size of a half dollar (one high on the furnace box and one lower on the blower box.) If you look downward into the window on the blower box you can see a red LED display that will sometimes flash error codes like E228 (one character at a time). If your model has something like this, let me know. I've done some DIY fixes recently out of necessity....and their easy.....and several technicians confessed they didn't know much, if anything, about the newer high effieciency Lennox gas furnaces.

The bearings are bad. You need to replace the motor. Motor cost $75 to $125. Labor is on avg. $150 to $400 with an decent A/C Company . You can try to oil it but its not recommend by Lennox. That furnace at the time they build it was top of the line. Good Luck.
