Heater Replacement Method 1 –
Using the prop rod.
This method has fewer steps than Method 2, but has a
higher risk of twisting and breaking the glass during
replacement of the heater. Use this method only if you
have good access to reaching around the propped
cooktop to replace the heater.
Perform Steps 1. thru 11. in the Glass Cooktop Re-
moval from Countertop section, then skip to Step 20.
in Method 2 below.
Note: To avoid glass breakage, use care not to twist or
lean on the glass cooktop while it is supported by the
prop rod.
Heater Replacement Method 2 –
Using a tabletop.
Perform Steps 1. thru 17. in the Glass Cooktop Re-
moval from Countertop section.
18. Have a clean, flat tabletop or countertop (at least
30 in. wide) available. Remove the prop rod and lift
the glass and metal subplate assembly away from
the burner box chassis.
19. Place the glass and metal subplate assembly ap-
pearance side down on the table with the 7 grom-
mets off the front of the table. This is to prevent
glass breakage while replacing heaters.
Caution: Only about 2/3 of the glass is resting on the
table. Do not push down on the front 1/3 without sup-
GEA00302
porting the front of the glass with your hand. Do not
force the glass assembly forward, as it will damage the
Left-Rear and Right-Rear infinite switch grommets.
20. Remove the heater's hairpin cotter clips and springs
from the defective heater.
21. Remove the defective heater with wiring intact and
lay to one side.
22. Install the new heater in position. Make sure the
metal locating tabs do not go inside the metal heater
can during assembly.
23. Reinstall the springs and hairpin cotter clips.
Note: If you are replacing either the bridge heater or the
dual heater, it is easier to complete the wiring if you
temporarily remove the HOT light bracket to provide
hand access to terminals.
Caution: Save and replace with the exact screws to
prevent glass breakage (#8-18 x 1/4-in.).
24. Remove heater wires, one at a time, from the defec-
tive heater and place them on the exact terminal
positions on the new heater.
