Thanks for the drawing, Surfdude. Just got back home a little while ago after driving through some heavy snowfall, which later turned into heavy rain.
Now this is something of a puzzle for sure, but I've heard that a little exercise for the neurons should be good for elderly people like me ( I'm 59 ).
I have added to the drawing, what we know so far. Also, I have added some text on your picture of the pcb in order to determine exactly what is connect to the terminals on the pcb. Very important. We can see that the two input terminals of the primary side of the transformer need to be energized all the time by the phase (L) and the neutral (N), 120 Volt/60 Hertz, otherwise the electronics won't work at start up.
Surfdude, please study my findings so far, and do correct it, if anything appears uncorrect.
A Breckwell P24 from 1988 differs from my Whitfield Quest Plus on several points... in particular the fact that it doesn't have an air flow switch
A P24 also has an extra snap switch of the N.O. type ( Normally Open ). I have found a very useful and detailed description of the overall functionality of the safety switches on a P24 on the Hearthtools website. This information really opened my eyes on how these important safety switches operate:
Limit switches:
Most Breckwell's have 3 switches: a. One 60T21 high Limit (over heat) thermo Switch. Normally Closed (N.C.).Click here for Test
If the stove gets over 300 Deg this switch will stop the supply of pellets even if the manual button is pressed. The combustion blower and convection blower will stay running to burn up the rest of the pellets and to cool the stove down .
b. Auger thermodisk 60t22 switch. Normally Open (N.O.) Click here for Test
This switch will close at 110 deg. allowing power to come from the control boards yellow wire after the 15 minute start up cycle. (The control board feeds power directly to the auger during the 15 minutes start up cycle through the ORANGE wire, after 15 min. power is fed through the YELLOW wire.)
c. Blower thermodisk 60t22 switch. Normally Open (N.O.)Click here for Test
This switch will close at 110 deg. allowing power to come from the Terminal strip to the combustion blower after the 15 minute start up cycle. This is how the stoves knows to shut off after the stoves cools down after the pellet supply is stopped.
(The control board feeds power directly to the combustion blower during the 15 minutes start up cycle, after 15 min. power comes directly from the terminal trip power supply mounted to the bottom of the stove.)
I also found a P24 owners manual that appears to be quite old, but maybe not old enough to cover your stove, Surfdude??.
But anyways, studying this further helped me understanding how a P24 works. I have attached this manual below this text.
It's getting a bit late here now, and tomorrow morning I have promised to take my girl friend to the hospital to make some blood tests. She has Diabetes II.
I promise to return tomorrow, when I have had more time to study how this thing "is ticking"
