For Westinghouse fj383 freezer where is the defrost timer located

SOURCE: Freezer defrosts too long.

Outside of HVACRH20 excellent advice, here a few stats about this model. The main control board will monitor the resistance of the evaporator thermistor. This is located near the top of the evaporator. This thermistor determines when the unit goes into and out of defrost. The bi-metal is redundant to the operation. It will terminate the defrost only if the thermistor fails. Check the values of the thermistor with the attached chart. Catriver..post back

The above URL will take you to an exploded view of the controls. Look at number 23 which will be located behind toe plate below door on the left side. That is the defrost timer. Rotate the clutch head screw Clockwise SLOWLY until you hear a loud click. That is the defrost timer starting the defrost. If the unit restarts after 18-22 minutes and defrost does not take place you problem is most likely the defrost thermostat.

The unit was built bt LG. It is a computer controled unit and the timer is built into the main control board on back of the unit. However, the most likely cause of the broblem is the defrost terminator located on the evap on the upper right hand corner. Also, try unpugging the unit it will reset the computer board. You will also have to defrost the unit.
