Vac switch doesn't start comb. fan. It is the other way around.Have you checked where control box plugs into for any damage?
 
The strip in junction box? Not close, kinda dumb that I didn't thought of it gave it a quick once over and back together. Will check that as well. So if comb fan has power the next place is vac switch?
 
If there is power to the comb. fan and it isn't running, it is bad. When stove is calling for heat, try giving it a spin to see if it is stuck. If there is no power to it, check the wire harness, otherwise the control box is bad. You can always bench test the comb. fan with power to see if it will work. kap
 
I wish someone was watching this post and could download the running sequence on here as I don't know how to do it. Dm? Tj?

Ok , this is wherever re my confidence goes out the window. Followed the wires from combustion fan back to a capacitor , has 4 prongs on it only 3 being used. 2 go to combustion fan the other jumps over from another capacitor right beside it on it's right. I have 178 volts on cap on right side but on the cap that is leading to the combustion fan nothing. I'm not testing it properly no doubt because the jumper wire is hot coming of off the other cap so either the cap is bad or I'm testing it improperly.
 
There should be two wires coming off the fan. Is there a connection you can pull apart in the wires and just run 110 to the fan to see if it works? Just the fan only. And are you mixing up wires of comb. fan with auger motor? Capacitor? I need to leave for a while, so hopefully someone else can step in and keep you going. look at diagram tj downloaded to see how stove works. kap
 
I'm testing the wire coming from harness along with the only other one I can get a reading from, 178 volts?? But I traced the blue lead coming from harness to the combustion fan cap and nothing. I'm confused what this jumper wire is. If it's factory or another add on by the original owner, there's been a few. Also cap to exhausted blower just sparked a lil and fan quit I wiggled them and it started again. So there may be something there.
 
IMAG0317.jpglooks good to me. Also the Brown wire on exhaust cap is shorting out inside the insulated cover on blade. Not sure if it's due to another issue or bad connection.Will try fan now some how
 
It's time for some pictures because I have NO IDEA what you are dealing with! How old is this stove and are you the original owner? Who has worked on the stove besides you? If there are so many issues with the wiring, it might very well be time to spend some money to get a new wiring harness and an electrician to rewire it. Test each motor and snap disc to make sure they all work and put a new harness in.
If I inherited that thing, that's what I would do.
 
Ok, just plugged fan in direct, after several tried I finally got the right combination of wires. It hums, trust but no dice.

What does that mean or are you using a cell phone with the darn 'completion' function that I hate so much?? :)
 
Post before you said fan was running till cap shorted. Now you say you wired direct and it only hums. Something is not kosher here. And if there are a bunch of wires in here from a previous owner, god only knows what goes on inside. I know finances are short,but I can only do so much over the internet to try and help. Read the diagram tj posted for you, so you know how stove operates. kap

From what I have followed of this thread, I believe he has a capacitor run motor on his combustion blower. That is why it ran when he saw a spark at a capacitor and it didn't run when he hot wired it on the bench.
Also, he said he saw 178 Volts. That is the peak Voltage of a 125Vac line. Meters should be reporting RMS not peak value. That makes me suspicious that he is looking phase to phase with a phase shift capacitor rather than line to neutral.
 
This is an old old stove.
 
Sorry guys, I'll try again. The exhaust fan was running but I saw a spark and it quit. The combustion fan hasn't been on yet since the fuse blew. I plugged it in direct no dice. It hums.
 
Not original owner no, I'm guessing someone else has worked in it as I have found issues I'm sure shouldn't be there. Certainly the factory didn't send it out with loose wires. It is a quadra fire 1100I it's old enough quadra fire has retired it.
 
As I mentioned I'm not very good with assorted colors wires. House wiring I'm good with, but not this. So I tested the cap that runs the exhaust fan only combination of wires that gave a reading was 178 volts, the reading leading to the combustion fan from wiring harness read 2.7 volts.
 
Is that diagram for my stove? Also no one not even my local dealer has a spec sheet on wiring diagrams. If I knew what the readings were I could have my buddy come by, he knows the language of electric. Just hard to believe a blown fuse , ( from dead short in igniter wires ) burnt up the fuse holder, blew the bulb and Burnt out the combustion fan. Who knows what else at this point.

The exhaust fan IS the combustion fan! If that is a capacitor start motor as Harvey said (I believe him), then it sounds like a new style motor and a rewire is in order. OR it sounds like a really jerry rigged setup.

It sounds like you're reading voltage drops and not applied voltage or voltage to neutral. It's time to get your electrician buddy a case of beer and an invite.
 
Here's the manual for the stove for the electrician. Sadly, no schematic but at least an explanation of each component.
Maybe the 1200 is close enough that he can compare wiring logic.

Well I'm at his house now, he was taught electrical by his dad a union electrician for life but like me hasn't fooled with electronic devices much so doesn't understand it either.tried to get a service man this morning but they are now backed up till 2nd week of January. This is my heat source and very limited in finances. So it's up to me. Cant afford parts I don't need just to eliminate them as the problem that's just not happening unless I know they are bad. Told wife and kids it's either heat and no Christmas or Christmas and no heat, even then it would be March before I could buy all these parts just as diagnostic tools.Thank you all, I believe I'm getting there, need a combustion fan sounds like since it won't run when pulled in directly. Then I'll go to next component I guess. Unless you tell me different.
