Where is locate the defrost sensor?

It is usually on the evaporator. Post a comment with the model number and brand, and I can tell you more. some refrigerators don't have a sensor for the defrost. They would have a clock style timer that tells it when to defrost.

Not defrosting

First, locate the defrost timer which may hidden behindcorners of the fridge at the back bottom, in some models located in the ceilingof the fresh food section or behind the cold control cover. Once you locate thedefrost timer, slowly turn the screw in the middle of the defrost timer withstraight screwdriver until the fridge shuts off. Now it's in defrost. If thedefrost heater(s) starts, replace the defrost timer and defrost thermostat. Ifthe heater(s) does not start, unplug wire cord to check ohm test for continuityof heater. If continuity is there, plug cord wire which gives power 120volts(check specification) to heater. If heater no starts, bypass defrost thermostatby join the 2 wires in the defrost thermostat. If the heater now comes on, replacethe defrost timer and defrost thermostat. If the heater itself is bad, replaceit. Thanks and hope helpful.

The cold control maintains the temp and their is a timer that either puts it in run for 10 hours or defrost for 21 minutesthemobilian_748.jpgThe compressor relay goes out on these. The defrost heater or defrost heater termination themostat can cause defrost failure if bad.Not much to these babys.

You have a defrost problem. You can defrost the unit down by removing the back panel and get a hair dryer and go back and forth over the defrost. Make sure that you don't get any of the coils too hot or you'll destroy your unit. But you'll need a meter to check which part or parts are bad. Do you have a meter? But you will either need a defrost timer, defrost heater or a defrost themostat. But you'll have to have a meter to OHM out the defrost heater. If your unit beeps then you'll need to replace the defrost timer and defrost themostat. If the heater checks bad then you'll need to replace only the defrost heater.
