Need location of defrost timer. refrig GE model #gsh25jstf

Hello Mary;

My name is Peter. I am a retired field service refrigeration technician.

You are locked in the defrost mode. About every 8-10 hours your freezer will go into a defrost mode for 20-30 minutes. This is where all of the components will shut down except for the light.

You have water on the floor because your condenser fan and compressor is shut down.

You did not provide a model number. Your model number is on the inside wall of your freezer near the top. So, I can only guess.

Lets take your freezer out of the defrost mode. In the lower back on the left hand side is your defrost timer (This may also be in the lower front depending on the model). Following is a picture of what a defrost timer looks like.



The time is mounted on the back of a plate and held on with two screws. The plate has a hole through it to give you access to the round knob on the left. The knob has a slot in it. With a flat head screw driver turn the knob clockwise. You will hear a click. Turn one click at a time until the freezer turns on.

The timer cost about $20.00. You can replace it yourself. Unplug the freezer. Unscrew the timer. Remove the connector on the right.

You need to replace the timer or you will have icing problems.

Send me your model number and I will tell you what the part number is.

Replace defrost timer in refrig cabinet. Located in the light and control area on top of refrig side. Remove cover, there will be a box with wires and a little wheel that is the timer.

Good day,
You will need an ohm meter to check the parts.
Your defrost system has failed.
It is made up of 3 components, 2 of which are located behind the rear panel in the freezer compartment.
Remove the rear panel. There is a cooling coil, that has a calrod heating element that runs along it's bottom. As well there is a defrost thermostat ( a small round 1" disk) which is located on the top of the same coil. Both should be checked with an ohm meter to test for continuity. The heater should read no more than 30 ohms, the thermostat ( IT MUST STILL BE COLD BELOW 30 DEGREES) should read zero ohms. Note: The heater rarely fails, the thermostat has a high failure rate.

The third item is a timer, or a solid state adaptive defrost control. Depending on age, and model, it is located , behind the kick plate on the bottom front.
Or, in the fresh food compartment on the roof.
If it is a timer, you can turn the timer shaft when the machine is running until the machine shuts off. With it still turned on, wait 40 minutes.
If the machine turns itself back on, the timer is O.K. if not, the timer is bad, and needs replaced.
If the Main heater checks O.K. and it has a solid state control, then replace the thermostat in the freezer compartment, and the solid state board.

Below is an excellant tutorial on defrost systems.

Thank you for using FixYa

If freezer is icing up, you might have a defrost problem. Frost free models have a heating element that is controlled by a timer to automatically defrost ice, defrost timer turns on defrost heating element every 12 hours to melt ice in freezer and allow good air flow.
You can test defrost element with an ohm meter(located inside freezer coils-will have two wires going to a plug connection), if OK replace defrost timer (located in various places depending on make and model
thumbs up

The defrost control is integrated into the main circuit board on the rear of the fridge.
You have to change the complete board.

The reason this happens is because the defrost timer is not turning back on when it needs to, causing the freezer to thou out and overfill the drip tray sitting on top of the compressor. A new defrost timer should be available from the local refrigeration wholesalers in your area.

I'm not familiar with this brand of refrigerator but sounds as if you have a defrost system failure. most refrigs have a defrost timer that you can maually advance into defrost. if you can loate this on the unit then advance into defrost cycle if the heater comes on youll hear a sizzling noise from the ice melting on the heater. this means you have a bad timer. if the heater does not come on then you have a bad heater or defrost termination switch. I tried to find some service info for this mod but was unable to locate anything. good luck peyton

send me the model number and ill take you through it step by step hold my rating till we are done you have a defrost problem its going to need either a defrost timer a defrost thermostat or the heating element
