The GE furnace is a model BLU055E936.

Problem: The blower motor hums and if I don't turn it off immediately,
it would burn up. I know this because this is the 3rd motor this
winter. The motor will get up to speed if you secure the service door
switch and wait for that moment when it just starts to hum and then
give it a push start with your hand. The blower motor won't come on
even when the fan is selected on the thermostat.

Attempted Fixes:
Everything electrical and mechanical has been replaced, which
includes:
Motor, Capacitor, Relay, Transformer, Limit Switch, Thermal Coupler,
Gas Valve, Fusible Link, Thermostat and all low voltage and hi voltage
wiring. All of the parts were ordered using the information on the
furnace. The wiring was rewired using a schematic for this unit. The
breakers and wiring where the power enters the house has be cleaned up
and new breakers installed.
We have even had an HVAC Technician come over and he was unable to
figure it out.

Is there anyone out there that can shed some light on a possible fix?

Thank you very much in advance.

could have replaced it with a modern more efficient model with warranty , for
all that youve spent on it

That's your third motor, and you replaced "everything electrical and
mechanical". You couldn't have used a competent service company, because 1)
they wouldn't have replaced all those parts, and 2) they would have had a
lot of them on their truck, and 3) no technician would rewire an entire
furnace because of a blower motor.

So you did all this work yourself, and THEN you called someone. If a
competent technician found out you did all that stuff, he's be wise to pack
up his tools and back out the door without touching it. He'd also be smart
to not charge you and give you nothing in writing saying he was ever there.
Way too much liability.

That furnace was made in 1979 or 80, and is about 65% efficient. Replace it
with a 90+ furnace installed by a reputable local company. That's the best
fix.
