Quadra fire control box or?

Ok new to the site but have read alot of posts so here is what I have CB1200 fs been working fine in house for years moved it out to shop and replaced thermocouple due to amber light. Now starts up perfectly but will not continue to feed pellets, reset snapdisk #3 no help, the control box now only blinks blue for setting NO other lights Control box bad?

Do you have a thermostat on the stove?

Yes, a Skytech handheld. Been great for years and batteries are new

If you removed the tstat you have to put a jumper wire in its place or the stove will not see a call for heat.

Make sure you have a thermostat in place, or a switch- the stove knows one of two things, you're calling for heat or not. The red call light needs to be on. You said you changed the thermocouple, its that thermocouple voltage back to the control board that gives it the signal to start feeding after startup. Green light on CB indicates 200 deg burnpot temp, red light 600 deg. Is the thermocouple out over the burnpot in its cover to the tip of the cover? Should hang over about 1 inch. On the 1200, red call light is on right side by heat level control. If no red call light on, no workie.

When you installed the new Themocouple, did you connect the red wire to the right side screw terminal and put the green ground wire over the red wire?

I too was wondering if tc hooked up right, but on a FS, doesn't it clip together only one way unlike the ins that you can hook up tc backwards? Thought on FS, it was easy to get polarity correct.

Your thinking of the short tc they use on sf and castile and older Mt v

This is a red and yellow wired exactly like the old one I photograph everything before I remove it I do not have any lights from control box except the blue at startup

Startup is noral until flae dies outmm,m

That is correct except that Quadrafire put out a grounding kit to eliminate a noisy voltage signal so the Thermocouple would yield a cleaner voltage reading.

So I made a ground jumper but still good startup NO lights or feed

 

[Overfireinthehole]

Bad board

 

[Overfireinthehole]

Although I would try running it with the vacuum switch jumped 1st just to make 100% sure that it’s not dropping out of vacuum after it gets hot

 

[Fishon256]

Update*** Installed a new board, has new thermocouple and ground wire, startup is great but no lights other than the blinking blue, NO GREEN light or anything else. Im lost on this thing.

Tc touching the end of the cover and sticking in the pot 3/4-1 inch? Tc connection on the correct terminals?

 

[Fishon256]

Thank you all for the help. It turns out it was something ridiculously simple The new TC has wire insulation backwards from y old tc. Stove is working normal again

 

[Ssyko]

Glad to hear that its back to normal
