I have a Goodman GMT-070 furnace that makes a very loud humming noise
when it turns on. It also isn't heating. Any ideas as to what may be
causing this? Motor? Transformer? I'm not going to try to repair it
myself, but how much should I expect to pay a professional?
This is Turtle.
It is very hard to tell what it is but could be a blower motor bearing
bad on the motor and just humming and stuck.
How much will it cost. ask the company you called what does a service
call cost. they will tell you
I rarely ever see a GMT blower motor bearing go out.
flue blower noisy bearing failure? sometimes test is: for one minute
have your licensed electrician or certified hvac repairman jump the
switch at the end of the flue blower's suction tube?
