7.0 BLOWER REMOVAL
Kerr furnaces have a blower sealing system, which is designed to be tight and rattle free
(Figure - 2). Use a reversing drill with 1/4” hex drive for the sheet metal screws.
1. Shut off oil and power to furnace.
2. Open blower compartment and if necessary remove lower rear filter support.
3. Disconnect wiring to blower motor.
4. Remove the #8 (1/4”) hex drive sheet metal screws securing the blower sides to
the divider panel.
5. Remove the rear 5/16” blower mount nuts.
6. Lift the blower straight up, keeping it level to avoid jamming on the blower mount
bolts and center panel. Shift the blower out of the furnace.
Secure casing insulation with aluminum foil tape to ease blower re-installation. Replace
the blower assembly using the reverse procedure. Ensure wiring and ground wire are
correctly reconnected.
