Component Testing; Door Switch; Warming Drawer Element - Whirlpool RF196LXK Technical & Service Manual

Before testing any of the components, perform
the following checks:
• The most common cause for control failure is
corrosion on connectors. Therefore, discon-
necting and reconnecting wires will be nec-
essary throughout test procedures.
• All tests/checks should be made with a VOM
or DVM having a sensitivity of 20,000 ohms-
per-volt DC, or greater.
WARNING
ELECTRICAL SHOCK HAZARD
Disconnect power before servicing.
Replace all panels before operating.
Failure to do so could result in death or
electrical shock.

DOOR SWITCH

Refer to page 3-12 for the procedure for servic-
ing the door switch.
1. Disconnect the electrical power to the
range.
2. Set the ohmmeter to the R x 1 scale.
3. Touch the ohmmeter leads to the door
switch terminals. The meter should indi-
cate an open circuit (infinite).
4. Press the actuator button and the meter
should indicate continuity (0 Ω).

COMPONENT TESTING

• Check all connections before replacing com-
ponents, looking for broken or loose wires,
failed terminals, or wires not pressed into
connectors far enough.
• Resistance checks must be made with power
cord unplugged from outlet, and with wiring
harness or connectors disconnected.
WARNING
ELECTRICAL SHOCK HAZARD
Disconnect power before servicing.
Replace all panels before operating.
Failure to do so could result in death or
electrical shock.

WARMING DRAWER ELEMENT

Refer to page 3-19 for the procedure for servic-
ing the warming drawer element.
1. Disconnect the electrical power to the
range.
2. Set the ohmmeter to the R x 1 scale.
3. Touch one of the ohmmeter leads to the
warming drawer element terminals. The
meter should indicate between 14 and
20 Ω.
