I installed a new Emerson condenser blower motor
in my home AC's outside unit in 2001. I tried to
start it up for the first time today since last fall,
and it was a little sluggish at first instant, but now
is okay, apparently.
I am almost positive that it stated "do not oil" on
the motor casing when I installed it, but I guess
I could be wrong, although I doubt it. Trouble is,
it was such a pain to get into harness when I
bought it that I am reluctant to take it out, just
to verify the "do not oil" part. Ya think I should
take it out anyway and try a few drops of machine
oil for good measure, or do some motors
specifically not ever need oil? Thanks for any

You should clean the motor every 4 months and oil it every other month

The extra torque in todays motors require a synthetic oil just to keep
them from overheating after 1 hr of continuous running. Dont use
machine oil. Use a good quality 3W24 SAE detergent oil. Apply 2.14oz
to each bearing every other month. After 1 yr you can lower it to
1.73oz every other month. Each year after you can lower it by .48 oz
per year until you need to oil it no longer.
Vacuum it with a dirt devil type sweeper every 4 months to keep the
dust out of the bearings.
This should make your motor last 10 yrs or longer.
Permanently lubricated inside of seals, until it fails. You can't get oil
where it would do any good, and it wouldn't last if you did.
If it is sticky getting started, replace it. Otherwise it will fail to
start and overheat your compressor, and then let's hope you have fail-safes
on the compressor so it isn't destroyed.
