Low Heat

Hey guys I've been following your thread about low heat on a Channing 111. I read everything posted about Channing's and have gained a lot of knowledge about these stoves thanks to this site. When I replaced my combustion motor, tray and plastic wheel last week I noticed that the wires on the new motor were reversed from the way they were connected to the old motor. The new kit came with the power cord already attached so I figured Alaska knew what they were doing when they put it together but you never know. When I am looking at the new motor the white wire is closer to me, on the old motor the black was closer. Does it make a difference if the wires are reversed, the stove seems to be running good. I might be using a little more coal then normal but I'm not sure with the cold weather we have been having. Doby I took your advice and checked the draft at full burn and set it right between .03 and .04. I have a direct vent and the manual and dealer said to set it between .02 and .04. Billyackiel glad to hear you have your stove up and running again.

Another "blame the wife" scenario ... lol

(don't blame her)

Enjoy your heat.

From what I've seen, DC motors will run backwards if you reverse polarity but with AC motors, they won't. Vacuum cleaners could run backwards if that were the case. Those are DC motors?

Also, if the combustion blower was running backwards, wouldn't they pull coal exhaust and fumes into the stove room?

Just curious..

No it would not create a vacuum. A squirrel cage blower running backwards just does not put out the volume it was designed to do.

Here is a picture of a new combustion motor, it does not make any difference how the wires are connected. If I reverse the wires and put the black closer to me it would not effect the rotation of the fan or squirrel cage underneath the tray. I don't know if my reasoning is correct.

Right.. if those are AC motors being fed AC current then turning the polarity around shouldn't make it behave any differently.. that's why I was a bit eyebrow risen about that solution.

But if they are DC motors, it would run backwards with a polarity change.

Funny short story for ya, I had a beater minivan that the switch for the power windows didn't work anymore. So, I installed an extension cord plug to window motor that hung out of the door handle. The other half of the cord was wired to the cigarette lighter. I would raise the window by plugging it in one way, then lower it by turning the plug around. My friends thought it was quite a hoot..

Correct. But if you would reverse how the fan blades are placed on the motor shaft, you probably would notice a difference in the fan output.That is the point I was trying to make. Maybe it wasn't spelled out correctly.........

Hey guys, thanks for helping me understand, I know the fan blades are on correctly and the stove seems to be working good. Pete

No no guys you missed one critical point he mounted the fan upside down, I knew and mentioned reversing the wires would not make the ac motor run backwards but suggested it cause I suspected the fan was running backwords but could not figure out why. As it turned out this made him double check what he did and discovered the fan mounted incorrectly

Yep and that was the op's problem after he cleaned the fan it somehow got mounted incorrectly, I am unclear on how far he tore it down but somehow the motor got mounted upside down and the volume just was not there thats why the stove ran but was not producing the correct heat

I took the motor completely apart. I had everything right except the large metal part with transformer or whatever its called. I put that part upside down, it is the same on both sides except for the sticker with model number on it. Witch is barely their on mine.
