After a short 15 minute search looking for a replacement 12 Vdc motor for my furnace with no luck. Maybe one of you has been down this road before and could point me in the correct direction The si...

"That" much as in 1/2 reduction? I hope so but am not holding my breath
The motor is rated at 6.5amps - Data from the Suburban web site
My 2025RV reads it taking 7 or 8 amps to do the job
Agreed its moving combustion air as well as room air
For me it's worth a few $$ to take a chance
Sure hope the manufacturer comes through with a nice motor
My Fan-Tastic fan motors are way more efficient that the cheap motors in the Suburban furnaces

I hope to - but am not setting my expectations too high - even a two amp current reduction would be nice and well worth the effort
The whole furnace is rated at 6.5 amps, but fully 1 amp of that is electronics and gas valve. The fact that yours is drawing above that does mean your motor is failing. The issue is amount of air moved- you can lower the current draw by blocking off some of the air flow, but that really isn't a good idea.
I'm sure you can lower the current draw, but I think only in the 10-15% range, or a half to one amp.
