I have been reading these forums every night for about a month, and have learned much from all, thanks.
I removed my nt 30 m furnace ser #1274480, ( It was made after the recal problem) Thanks again to you folks. I took EVERYTHING apart, cleaned all and foung the motor bearings are bad. the shaft wobbles and was making a noise while running, the reason for the dismanteling. The motors model # is ( I think) M5779, NT 32/ 30m , american posch, ser# ( again I think) mo 661250 12v
I would apprieciate any info : does any one have an old one, does anyone have a Intire old or junk furnace I could salvage the blower motor from. Am aware new nt 30 is nearly $500.
Thanks in advance
