Quadrafire Classic 1200 shutting off

[joe_pinehill]

I replaced the capacitor, the stove is running fine.

That's great news. Warm house and a spare on the shelf! I'm glad it was an easy one! That sure doesn't look like what was in the manual, though! Interesting.............. More work than I expected and it's also strange about the red wire.............

I double check, but I cleaned it yesterday, banged on the flue until soot stopped coming out.

Is it worth replacing the two snap discs?

No

What are the marking on that capacitor?????

I don't remember there being any markings on the capacitor, probably a "trade secret". But then again I don't pay much attention to them when I'm installing them.

there is no rating marked on the Capacitor. 250MMF is stenciled on it, which could be 250 mega mega farads? or just a supplier part number. For what its worth, my local dealer said he rarely changes them. Unlucky random failure.

They like most electronics do not like high temperatures. They tend to do strange things after a long exposure.

Judging by all the confirmed reversing feed motors and a lot of other problems that COULD be caused by a reversing feed motor, I would judge it's not as 'unlucky random' as we may think.

a micro micro farad is now called a pico farad. Instead of using the usual micro symbol (looks like a u with a tail) perhaps they used m..?? 250 pico farad is doable.

A starting capacitor with 250MMF in its value range is under $18, all of these drift in value over time and temperature, they also become leaky. This is one area where you stay away from new old stock.

the quadrafire OEM kit was $12 from my local dealer. I think its good to have a spare.

The Quad cap, is a small none starting cap.

I dont think its a starting Cap either, its to bias the winding/fields to have the motor turn only clockwise.

If it is a running cap they are a bit less however they like all capacitors will drift over time when exposed to heat inside the stoves shell.

Prices are based upon a number of factors one of which is the voltage that has be tolerated.

You are correct on the Capacitor. If the capacitor starts to go, the feed motor will occasionally reverse for no good reason.
A new cap resolves this issue see http://www.iburncorn.com/new-forum/34-quadrafire/5254-quadrafire-contour-feed-motor-capacitor

Even If you have a stove with the capacitor in the junction box like a contour, the in-line capacitor part # part# 230-2150 from woodheatstoves will bypass the cap in the junction box just by plugging in the wires and resolve the issue!!
