SECTION I SERVICE CHECKS WARNING: WARNING: UNPLUG OVEN BEFORE SERVICING. CERTAIN PROCEDURES IN THIS SECTION REQUIRE ELECTRICAL TEST OR MEASUREMENTS WHILE THE POWER IS APPLIED. EXERCISE EXTREME CAUTION AT ALL TIMES. IF TEST POINTS ARE NOT EASILY ACCESSIBLE DISCONNECT POWER, ATTACH TEST EQUIPMENT AND REAPPLY POWER TO TEST.
ON-OFF SWITCH CHECK 1. Follow steps 1-3 under the 4-Heat switch check except, using an ohmmeter check for continuity in the off position as follows: P1 to 2 P2 to 3 P2 to 4 If the above is not proven replace the switch.
TROUBLESHOOTING PROBLEM CORRECTIVE ACTION Range is completely dead. Check to insure the main store power supply is on. Check to insure the appliance is wired to power supply. Check to insure that the appliance power switch is on and that switch is not bad. Oven section elements are dead but top surface elements are working. Check for proper voltage and connections between oven section circuit breakers and thermostat. Check to see if the oven breaker has tripped or is defective.
TROUBLESHOOTING PROBLEM The circuit breaker trips after the range as been operating for a few minutes. CORRECTIVE ACTION The slow trip of a circuit breaker is an indication of overload in a particular circuit. The cause of this overload could be: Voltage problem, check element voltage against store and rating plate voltages. Element may also be defective; Measure the amps of the suspicious element and compare this with the expected value.
SECTION II SERVICE ADJUSTMENTS WARNING: WARNING: UNPLUG OVEN BEFORE SERVICING. CERTAIN PROCEDURES IN THIS SECTION REQUIRE ELECTRICAL TEST OR MEASUREMENTS WHILE POWER IS APPLIED TO THE OVEN.
