Jumpered the thermostat and still nothing. I'm trying to figure out these snap discs. I don't see that they can be reset, I'm looking St term wrong I guess. And the #3 snap disc. Is that way in where you can't really reach it?
The #3 snap disc lives on the back side of the auger tube near the top - not sure on the CB how accessible that is. If you follow the vacuum tubing up from its connection at the vacuum switch it should take you near to where the snap disc is. It has a tab in between the two terminals that is the reset - push it back down if it has popped up to reset it. If the #3 disc somehow tripped that would keep it from getting power to the stove.

That's what I thought, it's not popped. I took a thin rod and pushed it just in case. This stove is driving me nuts, I thought with the new fan I was all set
A pellet stove is a 'cruel mistress' sometimes, for sure ! I'm hoping your control box didn't get smoked somehow. You can try unplugging the stove, then remove and re-seat the control box.

They can look OK and still be blown - where you can't see the end of the filament. Do you have a multi-meter to test the continuity of the fuse, and to trace if you are getting power into the junction box ?

Unhook the thermnostat wires from stove, and jump the two screws together. Usually if the call light is not coming on, it is tstat wires or tstat. Since you pulled a bunch of wires loose, double check that they were all put back in the same place. kap
I did jump the thermostat wires together, I unhooked them at the thermostat end(it'd just a wireless control box behind the stove). I twisted them together and nothing. I don't get any lights, any fans, nothing. When the thermostat was hooked up I'd here that beep when I turned it to on. Nothing from the stove, lights, fans, noises, nothing.
Also also checked the fuse for continuity and it's good. I checked the wires up to the control box and it's getting power. The control box, or what I'm thinking, is the box with the fan switch and the red light and reset button?

I'm liking that dealer....who is it? Good deeds should be recognized.
(Edit) But not liking the current situation you're going through.

Hearthcrest in West MI, Byron Center and East Grand Rapids. I can't say enough good about them. They were great when I was deciding what to buy and when instilling it, and even now over 2 years later
That's the junction box. The control box on my Quad connects to the junction box - on your CB it may be in a different place - it is typically a clear box like in thread # 21 - it has a metal clip that holds it in.

Control box is in hopper on right side under a cover. What you are showing is your junction box. Control box is above it. You may have toasted it for some reason with wires messed up. Only way to find out is to uncover it and check it out. Make sure stove is unplugged first. And double check those wires. If there is power to control box, red call light should be coming on. Jump the screws on back of stove that tstat wires hook to. Make sure stove is plugged in for this test. Might just have a bad tstat wire or connection. kap

With the stove unplugged, release the spring clip that holds the control box in and take the box out, then re-seat it, then plug the stove back in and see if that gets power to the box.
If your convection blower mounting holes don't line up, I wonder if they gave you the wrong blower assembly? Did you keep the old one to check the number on it ?

I had to leave I didn't realize how late it was. But I unseeded the box and receipt at it and get no change. The motor lines up, but I noticed on the inside there's a metal piece that holds it up? I have it underneath and not on top of that so it's not In correctly
That's the same video I watched the other day. I thought maybe there was switch that keeps it from turning on. But it's definitely not in right from what I saw right before I left. I don't see how that's the problem, but I hope it is
Yeh, that shouldn't be affecting your power issues. I'd take kap's suggestion and recheck all your electrical connections - make sure there's no loose or bad spade connectors or melted wires. With the control box visible now try unplugging the stove, wait 30 sec or so, then plug it back in and see if you get a blue flashing light in the box, just to double check.
If there's 110v power going into the control and junction box, but no call light or control box lights then it's likely the box got shorted out somehow - a loose wire touched grounded metal or something. Quad dealers can usually test the control box, or put it in their compatible floor model stove and see if it reproduces the problem.
I'm not sure how your wireless t-stat is wired, but you're sure you got the t-stat jumpered ? Any chance the wires you twisted together are cooked ? Maybe try a separate piece of jumper wire as in the pic I posted above.

I was carefull with the power, it was always unplugged, so I'll be bummed if it's shorted out somehow. I'll rejumper the thermostat too. I might just pull the stove away from the corner tomorrow and double check everything while I can actually see back there too.
Thanks do much for all the help. Now go enjoy your New Years Eve
Sorry you couldn't get it running. I'd double check the wiring connections - it's easy for something to get bumped and disconnected, make sure the fuse is completely seated, and take your wireless stat wires off and re-jumper with a separate wire as you said, with fingers crossed it's something simple.
Happy New year to you and yours, DK

No worries? You've helped s ton and I learned a lot about the stove. slvrbkk saw my issue though. The wires were the issue. There's 3 wires for the motor, from the motor they are white, black, and red. Front he stove though, they are white, brown, and red. The black goes to the 120v. It's odd the colors aren't a little more clear, but if I would have looked closer they are zip tied in groups.
But, look at this:

Looking at your before and after wiring pics you posted, in the first pic it looks like you have a green ground, a double white, and what looks to be a grey or black wire attached to the power block, but in the after pic it looks like you have a green, a double white, and what looks to be a brown wire hooked up to it. The camera flash may be distorting the wire colors though.
I can see the double yellow connected to the one of the thermostat block terminals but I can't see what the other colored wire to it is. In the wiring diagram from your manual it shows yellow and black wires going to the thermostat.
