I have model g26q3/4-100-6.

The induced draft motor has been whining for over a year -- rather
loudly at times. I think it has finally died. It just moans now and
does not turn -- furnace will not come on.

I cannot seem to find a matching partnumber at the online parts
sites. Does anyone know what part number I need?

cozyparts.com seems to have the right stuff -- but I cannot find a
match between the values I read on my part and their website.

I see:

on the motor:
5899J43113
1Y25-734CS
on the blower housing
J16 5468
