Electrical Shock Hazard
Disconnect the range’s line cord plug from the wall receptacle before you service
any of the components inside the unit. Failure to do this could result in violent
electrical shock.
VOLTAGE CHECKS
When making voltage checks, be sure to observe the following precautions:
1. The floor must be dry. Water and dampness increase the chances of electrical
shock.
2. Set the voltmeter correctly for the voltage being measured.
3. Touch only the insulated parts of the meter probes.
4. Touch the component terminals, or wires, with the meter probe tips only.
5. Touch the meter probe tips only on the terminals being checked. Touching other
components could damage good parts.
PARTS QUALITY
An important step in the appliance repair procedure is the selection of FSP®
(FACTORY SPECIFICATION PARTS) as replacements. Use of “fits-all,” or “look
alike” parts could result in early parts failure, safety hazard, or substandard perfor-
mance of a WHIRLPOOL appliance. It could also result in an unnecessary repeat of
your repair efforts.
To be sure that the part(s) you purchase meet the exacting quality standards used to
build every new WHIRLPOOL appliance, be sure to ask for genuine FSP replacement
parts, as specified for your model. “FSP” is a registered trademark of WHIRLPOOL
CORPORATION.
You can buy your genuine FSP replacement parts from any authorized WHIRLPOOL
Parts Distributor.
