I have a PS50 pellet stove that is giving me fits this year.With the feed gate half closed,On high.It will run for 20-30 minutes and shut down.If I run it on medium,It will run for a few hours and then shut down.Maybe it will go thrw a couple cycles.On low it will burn all day but never get to the point to shut off.Wont turn the thermostat off.

I can hear the stove cooling down and I go downstairs and the red light is on and the stove is cooling down.The stove will stop.Then I can push the reset button and a way it goes.It will run for a bit and shut down.

One question I have is,When I disconnect the vacuum hose from the vacuum switch and blow in it.Should it act like its plugged,or is it actually plugged?

The stove and chimney are clean.

There is no blinking light telling me the t/c is bad.Went threw that last year.I know what that means.

Thanks.
 
I unmounted snap number 2.Left it on its mounting plate and letting it dangle.I will run it on high with feed gate 3/4 closed.It still rumbles pretty good.Hot pellets.That didn't work either.I guess I will leave it on low.
 
try closing the feed gate all the way when burning on MED and HI, and open the feedgate up a little when burning on LOW. On HI you should have an active flame 4-8 inches above the burnpot{page 10 in the manual under "fire characteristics"}...Frankly we never use high---even with the feedgate closed the fire seems too big....and after a while the stove "smells" hot.....luckily we dont need the HI setting as MED is plenty for our 1100 sf. Modular home....... some others will chime in re: the snap disc deal.......rumbling is a sign of too much fuel being delivered.... Good luck ! Keep us updated !

I have the feed gate all the way open and on low.It burned all night just fine.On med or high I close the feed gate and it will shut off.On high it wont go a few minutes but the flame is just crazy hot and the stove rumbles like you would believe.On medium I can get a couple hours at times.I normally wake up and the stove is off and the red light is on.
 
I just tried med with gate closed and went a few minutes.what ever it is,it's slowly getting worse.A couple weeks ago it would have ran on medium with gate half open.None of the snap switches are tripped that I can tell.I will stop by the place I bought it and ask them some questions.
 
Sounds like crud in your stove somewhere and the switch that is shuting it down is the vacuum switch.
 
It could be a TC that has a break in it and when it gets hot quickly it separates when the stove shuts down are there any lights on in the box?
 
The box light is green.What I did when I got home is disconnect the vacuum hose from the nipple.I stuck a drill bit in there and some very very fine sawdust came out and fell down the feed shoot.Were talking baby powder fine.I connected the hose to the nipple and blow.very little air can pass.It was totally plugged before.I think I need to get an air compressor and blow that fine sawdust out of there.Or remove auger and do it that way.I was told the nipple should be clear.

You can run a pipe cleaner in that barb on the stove end (do not do that to the switch end) and that should clean it out. It only takes a small amount of crud in the vacuum switch system to shut the stove's feed down. Never bypass that switch and operate the stove it is an important safety device and while they do fail it is rare so always assume that there is crud in the works.
 
I was reading another thread on here and solved my problem.The light on the control box would never turn red.just stay green.It said it was the t/c.I adjusted it and the stove runs perfect.Its always been a pain.The other thread had a trouble shooting chart.It was very helpful.

There are a number of things with a quad setup that leads to missed starts, one is low fuel feed due to vacuum issues or feeder gate closed too much or an older controller in a low temperature environment not being started on high, another is not getting the t/c and/or the ceramic cover positioned correctly, the cover with the t/c end touching the cover must be where it can get hit by the flame. The first step is to get enough fuel to at least get the t/c to signal we have a fire (both the vacuum switch and the positioning are critical at this time) then after the fuel starts being delivered again the fire has to get the t/c up to temperature for the stove to enter run mode (here it is the positioning becomes critical and in particular that the t/c remain in contact with the ceramic cover and that the cover is over the pot correctly).
 
glad you got it fixed.
