Attic fan maintenance
Hi all, any maintenance required on these electric ventilation fans? Mine is 20+ years old and running fine....should I go up and spray some WD40 on it or something?

Some fans have an oil tube that is used to saturate a wick that lubricates the shaft. If none is present, no maintnenance is required, or even possible. At 20 yrs, it will either last forever or will die soon.
