Heater Element (Figure 56)

Sheathed-style/Calrod heaters. Attached to the

same cartridge, Heaters A and B can be tested

independently of one another.

To replace a defective heater:

1. Ensure “Cool Down” process is completed (“Cool

Down” message will disappear upon completion)

and unplug the oven.

2. Remove Right Side Panel.

Disconnect Wiring Harness from heaters.

4. Remove Insulation Shield.

5. Pull back insulation where necessary.

6. Replace defective heater cartridge with

P/N HHB-8099.

a. Tighten flange nut

b. Reconnect Wiring Harness

c. Tighten jam nut

CAUTION: An over-tightened flange nut

may cause heater failure. To prevent heater

failure, hold a wrench to the flange nut to keep it

in place when tightening the jam nut. This ensures

the jam nut tightens to the flange nut, rather than

the flange nut tightening mor

e than it should.

7. Reset insulation.
