Pulled heating box from Holding Cabinet unit. Opened box and tested. Found element heating normally but blower motor not working. Checked for voltage to motor and found 120v. Tried to spin by hand and spinning hard. Bad blower motor. Will need to replace. Will order part and return. 9/30/19 Removed faulty blower motor from unit. Installed new blower and hooked up wiring. Ran unit up to temp and calibrated. Unit okay at this time.
