I have a roaring sound in my exhaust blower fan.

How do I clean the exhaust blower? Just undo the bolts and pull it out?

Hi Randy

I have rebuilt a few stoves including a Pelpro Bay View made by Canadian Comfort Industries who also make Danson and the older Vulcan stoves. They are all similar.

What model do you have? If you add it to your signature then you will not have to tell us all the time. :)

Anyways, I took pics when cleaning an Astoria Exhaust Blower which is also similar to yours.
See > https://www.hearth.com/talk/threads/wood-pellet-stove-yearly-cleaning-exhaust-blower-question.54566/

I like to use a putty knife to scrape the buildup under the blades and an old tooth brush or small wire brush on the blades.

When the blades are clean and shiny I use Spray Graphite for car locks on them from the auto store. This definately helps keep the blades from building up with soot and ashes so it will go longer between cleanings!

Now if you have a little time and want to save some good money, you can make your own blower gaskets real CHEAP with scissors and a paper single hole punch!

If that does not fix it, and it is an older stove with a exhaust blower that does not have a sealed bearing, some of them do have a high pitched wine. Then you need to get a new blower. I recommend a motor wholesaler like CSH incorporated on the web. Their price is half the OEM price.

Also if your Accutron II control board does not have the screw terminal block on the back for a T-Stat then you have an older control panel. Most of the older control panels did not set the exhaust blower to high on startup and sometime do not start the 1st time when the house is real cold because the blower is not running fast enough to keep the vacuum switch in, so it stops the auger from feeding pellets. Danson has upgraded control boards you can buy.

However make sure your stove is on a surge protector, these control boards are very sensative and blow very easily if you get a power surge or outage!

Good Luck

Don
 
Thanks Don for taking your time to help and here is a picture of the stove I have.

Hi Randy

Here is the Exhaust Fan removal steps for your stove. The Bay View is a Great Stove just like the one I rebuilt!

COMBUSTION FAN
Replacement Procedure:
NOTE: Always Disconnect Power Before Performing Service Work
You may find it easier to remove the appliance from the venting, if already installed, and
pull it away from the wall.
Tools Needed:
¼” Hex Nut setter & Driver 7/16” Thin Deep Socket & Driver Putty Knife or Scraper
Side Cutters or Knife RTV Silicone - supplied
Removal Steps
1. Unplug the stove power cord from the wall outlet.
2. To gain access to the inside of the appliance, remove the ¼” hex screws from the LEFT HAND
SIDE PANEL. These are located on the back left hand side corner of the appliance.
3. Remove the ¼” hex screw holding the wire harness clamp and the Green GROUND WIRE from
the combustion fan. This is located on the base of the appliance and off to the left of the fan.
4. Carefully disconnect the Blue and Double White wires from the IGNITER/LOW Limit switch (L120)
located on the combustion fan.. Be sure to hold firmly on both sides of each connection, then
wiggle and pull free.
5. For ease of fan removal it may be necessary to disconnect the Brown and Double White wires from
the HI Limit Switch (L250) and the Double Orange and Black wires from the FAN Limit Switch
(F140). These switches are located on the back of the firewall.
6. For further ease of fan removal, you may find it necessary to disconnect the AIR TUBE from the
Vacuum Switch.
7. Disconnect the Yellow and Double White wires from the Black Combustion Fan connections. You
may have to use your side cutters to cut any wire clamps.
8. Remove the 4 x 7/16” nuts that attach the combustion fan to the exhaust mounting.
9. Remove the used 1/8” fibre gasket and ensure the mounting manifold is clean of debris.
10. Unscrew the 4 - ¼” self-tapping hex screws holding the exhaust manifold to the combustion fan
housing. You will have to cut the RTV Silicone securing the manifold to the fan housing as well.
11. The Igniter Limit (L120) can remain mounted to the exhaust manifold, but if found on the fan
housing this will need to remove. Unscrew the 2 – ¼” self tapping screws.
 
No I didn't and what would that do if they are full? Thanks for your time.

Hi Randy

The ash trap cleaning instructions in the manual are not that good. So I made some better ones with pics below!

Here are the instructions to clean your ash traps!

ASH TRAPS: [COLD STOVE ONLY]
Remove the firebrick.
Then remove the back plate from the firebox area.(See Yellow Arrow of 2 Bolts Below) This will expose the two ash traps (Square holes in Backplane) and the fuel drop shute. Fly ash may be removed by vacuuming inside the 2 trap areas. It is also good to use a brush (bottle cleaner) to reach up and down to scrape the build up off the metal areas.

The vacuum mentioned above will work better with a long small hose attachment like in the second pic below
See second pic below.

Thanks for taking your time to help me on this and I cleaned the ash traps as you said but wasn't much in them. Maybe an inch in the bottom. I twisted off one of the bolts so had to drill it out and put a pan head screw in it's place. Believe it or not the roaring noise is gone after I got pissed off with it roaring all the time and gave the end of the motor a few wackes with a piece wood. Not the proper thing to do but that's it I guess lol. I oiled the end of the motor also but don't think that stopped the roaring?
 
You likely dislodged some ash or other crud between the impeller plate and the fan housing, or around the shaft, or inside the motor housing itself. Ash or dirt anywhere in the combustion air path can cause a pellet stove to roar.

Your convection air system can also make a heck of a racket if it gets cruded up just right.

These stoves can also whistle and make like a pipe organ.
 
I replaced the exhaust fan myself and it hasn't made any sound since. The bearings were gone in the motor...Thanks for the help.
 
Well...with the help from the members here,.. looks like youre on the right track again.! But back to your original question,.. I get a 'roar' from my exhaust venting sometimes even WITH a clean stove,.. but it is due to the fact the Im venting 4" from the pellet stove into a 6" masonry stack chimney once used for a woodstove. Once the flue temps reach a certain temp, the draw becomes so intense you can hear it roar!,... had the same roar when I had the woodstove hooked up to it. FYI
