Hi, I just joined the forum. Been a long-time reader and have enjoyed seeing and learning about the old parlor heaters in particular. This forum is a wonderful resource.
My own situation: I have a Moncrief coal furnace, circa 1960. This is a 24-inch round forced-air furnace with kidney. Very common type of furnace back in the 50's and 60's. Sears sold the same model under the name of Crane.
I began using this furnace about 30 years ago in my old 3000 sq. ft home. I've had to refurbish the kidney and some firebrick along the way. Still, the old gal heats well with the local bituminous I get from the mines.
Aside from the amazing jump in the price of coal in my Western Maryland location ...I've encountered a new problem. This furnace has a damper-motor which drives a chain, and that chain opens the draft-door below the firebox while simultaneously closing the flue-draft damper beyond the furnace. This damper motor is a 115-volt unit but also has two smaller lower-voltage switch wires which connect to an upstairs room-thermostat. I've had to clean and jury-fix this motor several times down through the years but now it's finally died. The trouble is, nobody sells this type of damper motor.
Question: Does anybody on this forum have one of these type motors and would care to sell it to me?
Or, is there some other type of damper motor that can be substituted? I saw a Honeywell 24-volt damper motor with an armature on EBAY, which I might somehow rig to the damper door below the firebox; and, since the existing chain still connects that door to the flue-pipe damper, it could work. http://www.ebay.com/itm/Honeywell-M7415 ... 5ae24ff595
This link is broken, either the page no longer exists or there is some other issue like a typo.
I presume I'd also need to acquire a 24-volt step-down transformer power-supply to run it? Or do these 24 volt damper motor contain their own step-down transformer?
Any advice or ideas you all could give me would be much appreciated.
