I have a twin flow kick space heater that used my water pipes and blows out air. It has been loud since we moved in a year ago, but in the last week it has gotten super loud. There is no obvious obstruction. Can I use wd-40 on the rod to the fan or any other suggestions?

If it's like mine, the motor is permanently lubricated and sealed. No way to oil it. By the way WD-40 is not a lubricant . It cleans and displaces water. If you clean something up with wd40 you need to apply a lubricant afterword

Thanks. I guess that means I have to replace the whole system...
