BROIL ELEMENT

TEST PROCEDURE

Refer to page 2-14 for the procedure for ser-
vicing the broil element.

Disconnect power from the range.

Set the ohmmeter to the R x 1 scale.

Disconnect the wires from the broil ele-
ment terminals.

Touch the ohmmeter test leads to the broil
element terminals. The ohmmeter should
indicate 45 to 55

Ω

Electrical Shock Hazard

Disconnect the electrical supply from the
unit before servicing.

Failure to do so could result in death or
electrical shock.

WARNING

Resistance Test (At The Electronic
Range Control)

NOTE: To test the broil element at the elec-
tronic range control, perform the following steps
(see page 2-4 for removing the top access
panel).

Disconnect power from the range.

Set the ohmmeter to the R x 1 scale.

Disconnect the P5-5 (blue) wire and the
red wire that is on the common side of the
double line break relay (refer to the sche-
matic) on the electronic range control.

Touch the ohmmeter test leads to the blue
and red wires. The ohmmeter should indi-
cate 45 to 55

Ω
