My Advantage 2 T got's the Wha wha's

The last couple day we have been running the Big Whit and the room air fan has decided to do the Wha wha thing (Likely the triac is to blame)

The fan speed control has never worked since we have owned the stove and will only make matters worse if I fool with it.

I have been working on the final version of my own control for the Adv 2 t but have been in no hurry.

The stove works great, but every so often it decides to make this harmonic noise that is annoying as all get out.

This is a common issue with the old analogue control boards, and in some cases they actually fail entirely and die.

No worries, as we have a good spare until I finish the new unit.

Wha wha wHAAAAAAAAAAAAAAAAA

This morning it's quiet

Maybe it healed up ????

 

I don't like the whaaa whaaa sounds coming from anything including ticked off or hurt kids.

 

The normal whizzzzzzz of the fans and the occasional pop or crunch of the hard shells being munched by the auger is no biggy and just part of the background.

When the fqan motor starts that wha wha wha noise it gets on my nerves REAL QUICK

I fiddled with the fan speed knob (does little except aggravate the fan wha wha) and the noise is pretty much gone.

The entire controller is going in the trash just as soon as I get the new Box assembled.

I started gathering the components now and after the holidays I will get after it.

I sort of have this thing "If it's working, DONT SCREW WITH IT"

Having the other ADV 2 T now I can roll it outside and use it to test the new controller and make any little tweaks needed.

Thinking about installing a 12 wire screw type molex connector in the side panel of the stove to make the install very quick and simple.

Ahhh yessss, projects

 

Thinking of doing a mod on the Fahrenheit controls for more manual control on the Auto-clean sequence & the thermostat smoother operation over-ride. It should be a challenge.

 

My entire feeling about pellet stoves is that they need to be a computer free zone.

Granted, they require some electrical controls, but since the micro electronics have found their way into the very fabric of our existence things fail far too often, or worse yet they flash trouble codes that nobody can fix.

The pellet stove manufactures used the same solid state relays that I am using in my custom controller, and did so until about the late 90's

Then all the companies started going to proprietary controls that are all made over seas (China mostly) for pennies (Their cost) and huge $$$$$ when we need a replacement.

The worst of this is that the micro controllers are so very fragile and any upset to the power flow or a failure of a motor or fan can wipe out the controller.

The fuse does not save the controller, it just saves you from burning down the house and the manufacture from a huge law suit.

If a component fails (Feed motor, draft fan, convection fan) the fuse should pop and replacement of the failed part should result in a completely normal resumption of operation.

Not so in this world.

Generally the failure of a major component will fry the board.

The reason for this is that the circuits in these tiny controllers are very very delicate and are designed to JUST BE ABLE to carry the needed current flow under normal running conditions.

Any upset wipes out the entire shebang (Read this as $$$$$$$$$$$$$$$$$$$$$$$$$$) and in may cases more than what the stove is worth if it's an older unit.


Engineered obsolescence and required service by the dealer.

Wrong answer where I come from

Get out the tools and make it better.
