Solenoid Check - Vulcan-Hart 148L Service Manual

SOLENOID CHECK

If the unit pilot is lit but the burners are not receiving gas, the solenoid may be malfunctioning. First verify that the
following conditions are true:
With oven door closed, turn power switch to the "ON" position. The power light should now be "ON" and the fan motor
should be running. (If the power light is not "ON", ensure that the unit's electrical power supply is properly
connected. If so, check the power switch for proper operation.) (If the fan motor is not running, check for
proper operation of the oven door switch.) All of the item checks listed above may be performed using the
components checks outlined previously in this manual.
If the above conditions have all been met, check the solenoid (Fig. 62), using a voltage meter for supply voltage at the
connector points of wires 24 and 26 (refer to unit wiring diagram located in this manual). Voltage should be between 110
and 120 volts.
Fig. 62
If voltage is verified but the solenoid is not cycling, it must be replaced. If no voltage is apparent, check for faulty thermostat
(thermostat is working if the heating indicator light comes "ON"). Check main connector plug and the centrifugal switch
in the motor.
NOTE: The connector plug is located on the outer body back of the unit. To check the connector plug, it will be necessary
to disconnect the unit gas supply and pull the unit from the installation area. The motor may also be accessed in this fashion
or by completely removing the motor through the oven cavity.
