I have a old (probably 1974 vintage) electric furnace that my repair contractor is having trouble finding parts for. The furnace says "International Heating & Air Conditioning, Weil-McClain, Utica,NY" on it, also says "International by W-M". Model Number is 133-015-GAB, serial number is H402962. The house was built in August 1974, this is likely the original furnace. It has a 2-year old Goodman a/c unit attached to it, the a/c works fine.
The furnace quit blowing warm air about a week ago, before that it was keeping the 3 bedrooms warm but the rest of the house was cooler. The air coming out of the vents has never felt hot, just kind of lukewarm even last winter (first winter I owned the house was 2006-2007). The duct work in the crawl space appears to be in excellent condition, no loose ducts or parts, seems to be pretty well sealed up and insulated. Problem started 1 week ago when I came home to find that even with the thermostat set on 75, it was 53 degrees in the house. Furnace was running continuously, blowing very cold air only (the a/c unit was NOT running, I even went outside to check). The HVAC contractor came out and looked at it and determined that the electrical "terminal block" where the main ac wiring from the house comes in and splits off to the various heating coils etc. etc. had burned up. Literally burned up with melted wires, connectors, etc. The fuses in the electrical panel inside the furnace (there are about 6 large glass fuses) were all good however. The thermostat is a a square Honeywell unit, looks old but from drywall repair around it, this seems to have been a replacement thermostat unit. Anyway, I have no heat whatsoever.
Could anyone advise where to look for parts for this ancient furnace ??
I really cannot afford the $$$ to have this furnace replaced entirely, repairing it is only financial option at the moment. Any advice on companies that might stock parts for older Weil-McClain electric furnaces is welcome
