Too many pellets

Good afternoon... found this site and learned about the photo cell"by pass". I have profile 20 & 30 stoves. The profile 20, puts out too many pellets during startup... it never catches up before the thermostat shuts off.
the stove slowly chokes. The auger is on the lowest setting and calibrated to its lowest limit. Is it possible that the control board is bad?

 

About 5 min.

 

About 5 minutes.

 

Welcome Steve270y hopefully someone can help you out...I myself have no clue about pellet stoves and such, goodluck...

More likely not enough air, from the air intake until after the vent termination needs a real good cleaning. There are internal combustion air paths and ash traps that get plugged on all pellet roasters that need regular cleaning. You are indicating that when you claim too many pellets are being feed.

What Smokey said

Before getting all excited about control boards and such, a complete cleaning of the fire box, ash baffles and the draft fan/housing is in order.

Check to see if the draft fan has lube ports and it it does add about 3 drops of high temp synthetic 0-20 oil to each port.

**** The oil ports usually have a rubber plug in them that must come out****

Make sure the draft fan turns easily and runs smoothly and at speed.

Remove the fan assembly from the housing and clean the ash/crud from the fan petals and the housing area and the passages.
**** Get a few fan gaskets as they usually break apart when removed****

Access the ash baffle area (Should be behind the fire brick) as these places collect tons of ash.

Vacuum out the entire baffle area and the passages.
****OWNERS MANUAL WILL OUTLINE CLEANING PROCEDURES****

Once clean things should work fine.

Most likely the airflow is low causing the slow light up and burn issue.

A ????
Does the stove feed pellets continually from the time you press start or does it feed some and then stop until the fire starts and then resumes the feeding cycle ??

Be safe and unplug the stove while working in the cabinet and take note of where wires plug in.
Smart phone cameras are sooooo handy.

Good luck

 

Greetings Steve270y, welcome to the forum - if you have access to compressed air w/ a nozzle attachment set @ 65-80 PSI, that is a huge help here in blasting any trapped ash out of the passages in the stove.. ( Just don't clean it in the house when the wife is around, ask me how I know. )

 

I've posted this before but there was a thread from years ago where a pellet stove technician kept a record of all service calls over a five year period and according to his records, about 70% of the time a thorough cleaning fixed whatever was wrong with the stove he was working on.

 

That would have been either Rod or Scott. Krooser claims the ESE says 80%.

 

So far I have: replaced the exhaust fan (spring)
Done the photo eye "by-pass"

Replaced the "fire brick" (found no clean-out ports) (this must be an early version?)

During the startp the burn box is nearly filled with pellets....my profile -30 only fills about 1/3 full.

The igniter will only screw in about 2 turns, then binds up. I decided not to force it.

Did a clean out when I did the photo eye by-pass (yesterday). Vacuumed everything I could reach. Used pressure cans of air to blow anything I couldn't vacuum.

Oh... replaced the door gasket a couple of weeks ago.

 

This is a great way to get a bunch of crud out of a stove and vent too. You just need to remember to disconnect a vacuum switches you have so the diaphragm doesn't get blown out.

 

Pages 24 and 25 clean out covers are at the back below the fake fire brick one on each side, make certain the burnpot ash drop plate is in the full in potion. Try the leaf blower trick.

 

Just double checked my profile 20 ..... no clean-out panels. Lol even took a photo. This stove is a profile 20 not a profile 20-2. I have the manual for a -2..... says that there are panels behind the fire brick...as you can see... NOT.

Guess I'll try the leaf blower trick!

Would like to thank everyone for their efforts. Great group.

I still think there are too many pellets..... but am convinced there isn't enough air either.

 

What are those screws for one on each sidewall? I haven't seen a pellet roaster that didn't have ash traps they are there your job is to find them.
