We have a Wesco furnace all the model numbers are worn off so no help there. My problem is it will kick on blow hot air for a min then turn off for a min and then back on. What would be causing this thethermostat? Also how do I replace the filters when I don't know what filters it uses I'm new to this whole furnace thing any and all info would help a lot

If you have a flame sensor clean it. If it is electric call for On Site service. I Can be of no further service since I am not familiar with Wesco especially without model numbers.

I guess I should have said its electric.

Wesco electric furnaces have not been made in many years and a supply of Wesco parts are not available. I believe one of your heat elements might be defective causing the erratic blower operation or it is possible a thermal disc is defective. You will be better served by calling for a On Site inspection of your furnace by a heating professional in your area to see if they can make some universal part work when the true nature of the problem is discovered. At that time you can also make a request of them to locate your air filter if one is installed. Sorry to be the barrer of bad news but Wesco has been out of business for many years. Do not be surprised if you have to purchase a new furnace.
