Removing the Heating Elements

To remove one or more heating elements, complete the following steps:

1. Disconnect the main power at the disconnect switch.
2. Identify the heating element:

a. Visually inspect the heating el be cracked or broken.
b. Perform a resistance check across the element. No resistance indicates an

open circuit or a broken heating element.

3. Remove the side access panel screws on the side of the furnace containing the

broken heating element.

4. Loosen the three side access panel screws located on the back of the furnace.

The screws do not need to be removed.

5. Remove the side access panel.

6. Carefully remove the stainless winged M clamps holding the braided aluminum

interconnecting straps to the aluminized terminal extensions (lead sections) of

The heating elements are extremely fragile. Handle these

elements carefully
