Harman P61A - Loud noise this morning

[Emmie]

We woke up to this noise coming from our Harman P61A this morning. It is very loud but running normally other than the noise. Maintenance this year has not been real good due to illnesses. Any thoughts? Thank you.

It sounds like fan noise. I would first turn off the distribution blower to see if the noise still exists. If the noise stops then I'd check it for something rubbing like a wayward pellet.

Thanks. Is there a way to turn off just the distribution blower to pinpoint the problem? It's going to be 65 degrees today so we can turn the entire stove off.

Turn the temperature setting down or set the stove to OFF. In the OFF position the combustion blower will continue to run until the stove completely shuts down.

Thanks. S/O has shut off the stove and is taking apart to perform long-awaited maintenance.
