PS40 will not stay lit

[Murph]

Have a PS40 that begins start process but will not stay lit and eventually you are left with a burn pot full of pellets and no fire. Have replace POF switch and closed down the damper to about a half inch. The stove is brand new and clean as a whistle. The pellets seem to fire up close to the igniter but the fire does not spread throughout the burn pot. Still plenty of air getting into the pot as evidenced by the blowing embers. Eventually however the igniter stops and the process slowly dies with the POF never being activated.

Did you have it installed? or do it yourself?

This will help the guys give you some pointers.

Are you running the stove with a thermostat? At the bottom of the control board there are thermostat terminals. It's a green square with two wire terminals with screws. There should be a jumper wire bridging this terminal if you are not using a thermostat to call for heat. If you are not calling for heat then the unit kinda thinks it wants to shut down.

If there is anything between the igniter and the walls of the tube it is in there is likely not enough air going past the igniter to light the pellets, the superheated airflow does the lighting.

Check the area around the igniter for possible blockage.

Also a number of burn pots need to be precisely lined up with the igniter.

Check and correct incorrect burn pot alignment. That air I mentioned above needs to get to the pellets that are outside the igniter tube.

It is also possible that the igniter is incorrectly positioned in its tube. Remember the igniter is also an air flow blockage.

Thus if it is level with the end of the tube it is in it may need to be pulled back a bit, however it is also possible that it is sitting too far back and can't heat the air enough.

Adjust its position in the tube.

It is also possible that there is too little air entering the tube the igniter is in.

Check for blockage around the tube and clear any found.

There are frequently several air paths that enter the area of the burn pot, one on the left, one on the right , and through the igniter tube (usually in the middle). Thus judging air flow in the pot by glowing pellets doesn't tell you if the amount of air is either correct in total or is going through all the places in the proper volume it needs to to light the stove.
