SEVERE EQUIPMENT DAMAGE OR PERSONAL INJURY!
A. Remove the Oven Element Cover [52] by removing the two thumbscrews from each side. Pull the
Element Cover down and to the front of the Oven to remove it.
B.
Remove the Outside Top [71] of the unit to expose the wire leads for the Oven Heating Element
[6] you intend to replace.
C.
Remove the Side Access Panel [74] from the right side of the unit. Follow the wire leads from the
defective Heating Element to the front Contactor [3] and disconnect them. Make sure all the
disconnected wires are free of constrictions and restraints.
D. Remove the Heating Element mounting screws from the inside of the Oven and remove the
Heating Element from the support bracket. Pull the Heating Element and its wires from the Oven.
E.
Remove all old sealant from the Heating Element mounting holes with a putty knife or scraper.
F.
Run a 3/16" bead of high-temperature silicone or gasket sealer around each Heating Element
passage hole in the ceiling of the Oven.
G. Feed the wires of the replacement Heating Element up through the passage holes and push the
replacement Heating Element into place. Secure it there with the support bracket and the mounting
screws.
H. Run the Heating Element wires over the top of the Oven and down over the side insulation to the
Contactor.
I.
Position the Heating Element wires where they will be out of the way. Make sure you have enough
wire lead to make a safe and secure connection, then cut off any excess wire. Strip approximately
½" of insulation from the ends of the wire leads and fasten them in the Contactor terminals. Make
sure the wires from each Heating Element go to separate terminals on the Contactor.
J.
Replace the Outside Top and Side Access Panel, being careful not to pull or pinch any wires while
replacing the panels.
K. Restore power to the unit and test the Heating Elements for proper operation.

Replace the Oven Element Cover. Make sure the ½" flange on the back of the Element Cover fits
into the guide strip welded to the ceiling of the Oven and that the Element Cover is all the way
back and tight to the Oven ceiling. Tighten the thumbscrews securely.
