Whitfield Adv. 2 shut down twice last nite?

[John C.]

Ran the stove from 5 pm until 1-2 in morning when my wife said it shut off. Running heat 3 blower on 4.
Let it cool down restarted it and shut off again about 6 oclock when i left for work. Before the second relite i opened the damper more to allow more air thru.. Both times the burn pot was empty. Burnning Inferno's. I think it is the high limit switch but IDK. any help would be appreciated.

LOL,

That's a new one, burning Infernos and high limit in the same post.

On the feed disruption side, check your vacuum line for ash and tell us all about the last time the stove and vent system was cleaned and what on the stove was cleaned and how it was cleaned.

On the removing excess heat side, check your convection blower for dust bunnies and such in the blower wheel, the motor's cooling fan, and inside the motor's shell and clean them if needed (compressed air, vacuum, soft brush).

 

[John C.]

The vacuum line was cleaned a week ago when i had the sheild off (ins.) Begining of season cleaned the ash traps behind the brick. Did the blower thing on the top of the chimmeny a couple of weeks ago.The stove is new to me but used didnt even put a half ton thru it. I might just trade it in for a newer stove.

 

[John C.]

yes made the mistake of buyin Infernos

LMFAO

 

[John C.]

Ill come down and see u next time CT Pellet. So dont give me any BS. HAHA

Well if those puppies are producing what I've heard of for ash levels, you need to completely clean your stove including the combustion blower etc ....

A full deep clean is needed.

But on the off chance you are over heating do the convection side of the house and see if that takes care of your problem. Who knows you might get more heat out of the stove as a lot of others have discovered after really cleaning the convection blower.

Might as well do both.

 

[John C.]

I dont get you.You mean turn the room blower Higher? What else can it be. The auger lite blinks but nothing comes down when it shuts down. Thanks by the for the help.

 

[John C.]

Do limit switches get weak? Or are they good or Bad?????????????

 

[SmokeyTheBear]

They can get flaky but usually they fail, what can happen though over time is they get crudded up and can no longer sense the true temperatures.

The area behind them gets ash deposited on it and provides insulation.or if the unit sits in the exhaust stream it actually gets dirty with ash same results.

 

[SmokeyTheBear]

The auger system can also come into play here as well.

If your POF is one that looks through the drop chute to detect flame (some whits did that) then fines or scratches etc... can cause issues.

No clean the blower's squirrel cage and and motor. That allows the blower to send the proper amount of air through the heat exchanger.

 

[John C.]

Ok Smokey you a fireman? I dont think i have a POF if thats a photo eye. Pokin around the internet i have learned there are two high limit switches i guess, a inlet high limit and the one one the exhaust blower.

 

[SmokeyTheBear]

Nope not a fireman.

The manuals for the stove should tell you if your POF system is a photo-eye or snap disc or thermocouple.

If your stove were to trip the high temperature limit it will stop power to the auger and depending upon the nature of the high limit system it may restart the auger once the temperature has dropped enough (this is an auto reset system) or require you to reset the tripped high limit switch (manual reset) some stoves have a couple of switches that act as high limits one of them being automatic reset and the other being manual reset in this case the manual reset one is usually a burn back protection device mounted on the drop chute.

Now your stove has two ways to get rid of the heat produced by the fire both of these involve the heat exchanger, the first way is out of the stove and "up" the vent and the second is into the room vai an air flow created in the heat exchanger by the convection (aka room, distribution) blower or fan but the blower and the fan need to gather air and send it into the heat exchanger, if they have dust, etc in their input areas or on the fan itself they can't move enough air to prevent the heat exchanger from over heating and tripping the high limit system.

 

[John C.]

Ok thanks. They are auto reset.I'll pull the blowers out tommorow and check for crud. Thanks again.

 

[Pellet-King]

Might be your auger is stopping, there's a shim on the auger motor that wears and the gear shaft drop's slightly, but usually it wont move at all after it stop's

 

[John C.]

Yes thanks Pellet King. After it cools it starts again.We bought it from Deans Stove,going to talk to them tommorow. UCONN men are playing now.

 

[Pellet-King]

Go Uconn!, keep us posted John, I work in glastonbury could give you a hand if you need it!
Keep them ole Whit's a running!

 

[John C.]

Ran the stove all nite,went into standby around midnite,but no shutdown,pulled the draft control out to 1/2" from full turned down the feed a pinch. The pellets burn hotter than u all think. Just remember the speech that CT PELLET gave about not being the same from one year to next or one batch to the next.

King what kind of pellets do you burn and what settings for draft?

Nobody that has been burning for bit questions that pellets burn hot and some hotter than others and that there are variances between different batches of the same pellet.

Batch variance usually is rather minor on the heat end and more prevalent on the ash side. There is even variance within a batch.

No matter what causes the heat the exchanger still has exactly two means to dump it.

There is far more variance in the air flows involved there than most folks realize, a very thin film of fines dust on the vanes of a squirrel cage can have a very large impact on the air flow into the room and the temperature of the exchanger regardless of the fire.

This is also true on the combustion blower side as well.

If you lowered the temperature of the exchanger by reducing the amount of heat being created that is also fine, but I'd still check at least that convection blower because if you had that room blower set for the heat setting you were running at the limit switches should not have operated and the stove should have continued operating.

Smokey you where right both ash channels were almost full to the top.But i only have to deal with it for a couple weeks we traded in for a Avalon Astoria. I bought 3 bags of energix green to try. If I buy a ton of good pellets can I mix the infernos in to get ride of them,i know i'll have to deal with the more frequnt cleaning.

 

[SmokeyTheBear]

You can mix the two together and cut down on the ash being produced on a per load basis. I understand the wish to get rid of the high ash pellets really I do, I've been there. It was not fun and I had a few high limit shut downs.

If your vent is such that you can easily get to it a good dose of leaf blower can get a lot of the ash out easily up until it is really packed into the system and had a bit of moisture go to work on it.

 

[Pellet-King]

You Trader!!

 

[DirtyDave]

hope you cleaned the hidden channels also
