I've got an old Monogram oil stove that was used for home heating. Has a reastat run fan built in to oil flow control. Just lately has started to lose fan speed after an hour or so running. Visual inspection of reastat and electronic spray cleaning hasn't changed anything. Fan spins freely and have oiled it to boot. Is it the fan motor dieing or reastat failing? Have owned it 50 yrs. I suppose a voltage check out of reastat is what i need as it just starts slowing down. Shut it down for a while and it works again. Don't know what to do. Used to heat my shop. Any ideas? TIA that fan has alot of hours on it. How would a pro diagnose it?

i would bypass the thermostat.. Run power straight to the fan and let it run wide open all day long... Would be a good test to determine if the motor has a problem... Old windings could be breaking down when hot, or bearing could be expanding with heat and causing a little drag...

Yeah i wonder if it has brushes. Need to try your suggestion first before tearing into. I don't understand why stuff don't last forever......
