CENTRIFUGAL SWITCH CHECK (Cont.)

CENTRIFUGAL SWITCH CHECK (Cont.)

Fig. 65

Using a volt meter, measure the voltage (110-120 volts) between Wire #23 and ground, and Wire #22 and ground. If voltage is present, or if only one wire (#22) has voltage, the centrifugal switch in the motor is bad. The entire motor must be replaced (see Fig. 65).

NOTE: If line voltage is not present on either of the wires, recheck door switch, power switch and thermostat operation.

REMOVAL OF CONVECTION OVEN SOLENOID (90 Series Only)

NOTE: This procedure should be done only after the checks for the thermostat, connector pin and centrifugal switch have been performed.

NOTE: Replacement solenoids come with only one plug. The other plug must be removed from the old solenoid and reinstalled with the new part.

TOOLS REQUIRED: 11/16", 1/2" open end wrenches or 6" adjustable wrench and needle nose pliers.

WARNING: DISCONNECT ELECTRICAL POWER SUPPLY AND PLACE A TAG AT THE DISCONNECT SWITCH TO INDICATE YOU ARE WORKING ON THE CIRCUIT.

1.Disconnect unit from main gas and electrical supplies.

2.Disconnect 11/16" NPT straight fitting (1) at right-hand burner tube, and (2) at the safety valve (Figs. 66, 67, & 68).
