TROUBLE SHOOTING
The following is intended to provide a guide for trouble shooting
procedure and covers some of the more common problems
with the equipment. As with any other equipment, the servicing
personnel working on this equipment need to become familiar
enough with the circuit and the components in order to be able
to follow a logical sequence of trouble shooting and to repair
malfunctions not mentioned in the following paragraphs.
The instruments necessary for trouble shooting:
A. A.C. voltmeter to measure line voltages up to 500 volts.
B. A.C. ammeter to measure live currents.
C. Accurate thermometer to measure the temperature.
In the following paragraphs, the voltmeter is used to measure
the voltage between (2) phases on 208, 240 and 480 volts, and
between the phase and the neutral on 220/380 and 240/415
volt supplies. Do not measure the voltage with respect to the
chassis ground, For the sake of simplicity, the measured
voltage is referred to 208 volt, assuming that the supply is 208
volt. When the supply is 220, 240 or 480 volt, the measured
voltage should also be 220, 240, 480 volt. Refer to the
appropriate wiring diagram packaged in a separate envelope
marked wiring diagrams shipped with this unit.
With the main power, range's breakers, thermostat & the infinite
switches turned to "ON".
E-60 & E-60-F MODELS
PROBLEM CORRECTIVE ACTION
Range is completely dead Check the main disconnect switch & the supply leads
No heat in either of ovens but top surface
elements are working.
Check Voltage between leads #7,16 & 23 on the circuit breakers.
If 208 volt, check lead #7 for proper connection to the breaker and the thermostat
If no voltage, measure between leads #1 & 4 on the same breakers.
If 208 volt, the breaker is either off or defective.
If no voltage, check for proper connection to the terminal block and the main supply voltage
No heat in left oven, but right oven & top surface
elements are working.
Check voltage between leads #16&19.
If no voltage, check for bad connection on leads #7 or 19.
If 208 volt, check voltage between lead #16 and 17 (thermostat)
If no voltage, thermostat may be defective.
If 208 volt, check for bad connection in leads #17 & 24
No heat in right oven, but left oven & top surface
elements are working.
Follow step 3 above except lead #18 replaces #17.
Only the top element of the oven not working. Check voltage between leads #26 & 27 on the infinite switch.
If 208 volt, measure at the element terminals.
If 208 volt, the element is defective.
If no volt, check for bad connection on leads #26 & 27.
If 208 volt, measure voltage between L1 & L2 terminal of the infinite switch.
If 208 volt, the switch is defective.
If no volt, check for bad connections in leads #22, 23 & 24.
Only the element of the bottom oven not
working.
Check voltage between leads # 16 & 17 (or 16 & 18 for right oven) on the element terminals.
If 208 volt, the element may be defective.
If no volt, check for bad connection between leads #16 & 24.
If 208 volt, check for bad connection in leads #17 or 18.
If no voltage, check for bad connection in lead #16 or the thermostat terminals.
