Grisbi Posted February 7, 2015 Report Share Posted February 7, 2015 Hi Everyone, I am new to this forum and I am learning about my westco electric furnace. I don't know the age but it must be over 30 years. 40? Anyway I have a fan switch with a bimetal part that actuates the cutoff for the furnace. At least I think thats how it works. Its a Honeywell L4069C1009. I tested the connections for continuity and the circuit is closed when I manually actuate the bimetal switch. It was removed by a technician who said it needs to be replaced. Is there a standard part that can replace this item? How do I test the original part to see if it is broken. Sorry for the long post but I am new to this. Thanks. Quote Link to comment Share on other sites More sharing options...
Jim Katen Posted February 8, 2015 Report Share Posted February 8, 2015 If you google the part, you'll find that replacements are readily available for $120 to $150 online. Other than manually actuating it, I don't know how you'd test it. Maybe Plummen has an idea. Quote Link to comment Share on other sites More sharing options...
