Stove shuts down while fire is still burning

[pangia]

Stove is a Castle HPS09.
A few minutes after startup, it shuts down.
Flame is still high when it does that.
Blowers and auger are working, and there are no clogs in any of the vents, but when the stove shuts off it kills power to the blowers too, and smoke isn't exhausted.
Any clues? Thanks.

Sounds like the proof of fire switch. The stove thinks there is no fire and shuts down.

No trouble codes or beeps? Have you cleaned ash trap? See cover plate clean-out (item 11 on stove exploded view of stove on page 22 of manual)
(broken link removed)

I use a lint brush and hose attached to my shop vac so I can get into the upper reaches of the machine... depends on the configuration of the internal smoke pathways.

PS - Welcome to the forum ... best to put stove type in thread title to catch the eye of other owners with the same stove

Thanks for the info Tim - I bypassed the POF switch and the stove kept running as it should.
The switch I have to replace has this number sequence on it -

610044
T-O-D60T12
0921
F110-20F

I've found several switch online that match except for the 0921 number.
Would you know if that makes any great difference?

Thanks

Thanks for the info - It seems my problem is a bad POF switch, but I didn't know that extra access panel you mentioned was hidden behind the rear grill, and it did need to be cleaned out.
