wall furnace - it's a Sears ( model 867736230 ) and am aware that it has 3 snap discs ( limit, fan, and thermostat ).

The thermostat snap disc seems to be defective. I can't make out the (1) STOCK NUMBER, nor the (2)VOLTAGE on it. I also can't get (3) SCEMATICS on a diagram for these discs. Is it possible to get answers for the these 3 concerns ?? Thanx

It is time to get the furnace ready for the cold weather. If you need parts, a good place to get the parts and view schematics is Sears Parts Direct. I attached the link for your model below. I also added a general article and diagrams for a thermostat. It may help while you wait for the expert to answer.

I don't have technical information available for this older wall furnace.

The only information available for this furnace appears to be the parts list diagram on the

Sears PartsDirect

website. I see the limit switch (Key 45) and the fan switch (Key 46) shown on this parts diagram. I do not see the 3rd disc on this diagram. You may be able to determine the switch that you need from the diagram. I don't have voltage information or wiring diagrams on this model.

I recommend that you have a service technician look at this furnace. A technician may be able to determine the parts that are needed based on physical examination of the components. Here is a link for the Sears Service website:
