Where can I locate a list of replacement parts for a Wesco furnace that was installed in a mobile home in 1965? Thank you.

You probably will not be able to locate parts for the old Wesco. There has been many posts here and on other bosrds about this problem. I have searched all over for parts and none are available. They also used a special ribbon type heating element so the standard replacements available for other brands will not work either. If you ever find a place that has the parts please post the company and phone number because folks doing a Google search or other search will be glad to know they are available.

Only real option is to replace the unit. Sorry

You'll have better luck purchasing a time machine and travelling back to 1965. Let me know if you find one, I'll ride shotgun and navigate.
