    Blower assembly vibration, Heil gas furnace
    Heil gas furnace model GDE075F16A3. The furnace just quit working. The fault was a broken lead on the secondary of the 115V to 24V transformer. With the furnace operating again, I noticed that the blower motor/fan assembly was vibrating. The wife and I removed the assembly for inspection. During disassembly, my wife discovered a broken blower hanger bracket--see photo. I inspected the blower wheel and motor assembly but found nothing unusual. The balance weights were attached and the motor was securely attached. Spinning the blower wheel by hand, I noticed a bit of wobble and there is some lateral movement in the motor shaft. As a temporary repair, I drilled a hole through the bracket and whatever the other part is called then reinstalled the assembly. Which part is most likely causing the vibration, blower wheel or motor? (out-of-balance blower wheel or bad bushings in the motor)

    Sounds like your bearings went out. Definitley cheaper to replace the motor than rebuild it

How do I remove the blower/motor assembly to an Ultra 97 gas fired furnace? [ 1 Answers ]

The furnace is approximately 20 years old and is a Model Ultra 97. I can not locate what is holding the blower and motor assembly in place. It looks like the assembly should simply slid out from the side, on two tracks. It won't budge, but I see nothing that seems to be holing it in place?

Heil Furnace blower won't come on UPDATED [ 3 Answers ]

Ok It is a Heil gas furnace. No belts. The motor I hear running is apparently the electronic ignition that comes on when I turn the electric on to the furnace. The burner fires, heats and goes out once heated up, no blower comes on. I was told to clean the heat sensor since it may be corroded....
