Where can I find parts for a Wesco furnace Model 15 UEM

Some parts are universal. This company has been out of business for years. Search the net like I did for this.

I am looking for a wesco electric 1725 furnace hermocouple for a 1974 mobile home.we just bought our home an found out the furnace isn't putting out any heat.

Standard restring kits will not work on UEMs They had "W" shaped finned calrod elements. The UEM used a solid state control board to sequence heating elements and their thermostat was a DC voltage proportional thermostat that was indiginous only to the UEM model furnace. Also all of the heat relays in the unit are 24 volt DC. The best repair if the elements are intact, is to remove all the UEM stuff, and the wall stat, and replace with a sequencer, and standard 24 volt thermostat. Any reputable service agency should be able to do this upgrade.

No thermocouple on an electric furnace. Describe the part and what it does.
