There is no defrost timer on a GSH25JSXBSS Can you provide an actual freezer temperature? Feel the base of your ice maker to see if possibly the heating element is staying on after dropping the ice into the ice bin and look for the ice maker to see if excess water is flowing into ice bin once it refills. Are other items defrosting in the freezer due to extended defrost? I am here should you need me, Thanks John Tripp Appliance 911
The only thing that tells the machine that a harvest cycle has completed and takes it back into a freeze mode is the ice level control. when the machine go's into a harvest the ice drops through the ice level control and brakes the beam and switches the machine back to freeze cycle. Pull the the ice level controls and replace them. if there is nothing wrong with them than it is the electronic controller. part number for ice level controllers are 11-0540-21. The part number for the control board is 12-2838-24
Did you clean the float switch water tube going into the water trough when the switch was replaced? Does it make 1 drop of ice,then shut off immediately? What is the age of the machine?
3 beeps every 3 sec. = Freeze Back Up Timer. Freeze > Specified Setting Yellow LED marked "F Timer" energizes. Check for F/S stuck closed (up), WV leaking by, HGV leaking by, PM not pumping, TXV not feeding properly, low charge, or inefficient comp. Dip switches 9 & 10 allow for factory adjustment of this back up timer feature.
The control light flashes to indicate the infrared beam is being blocked. The flap on the opposite side blocks the beam when the door is open to prevent ice from being dropped on the floor rather than in the ice bin. If you pushe the flap in so it's flush with the liner (use care not to block the hole) the light should go from flashing to on in a steady state. If not, your electronics are bad and would need to be replaced. If the light does glow steady, then the problem is with your ice maker, water valve or ice maker fill tube.
Thank you for following up with me. The machine works fine now. I should not have sent my message under the category of "similar problem" since I had already fixed it. My solution was simply to gently pull the sender and receiver units out, give them a good cleaning, and put them back in. Each unit looks like 2 LEDs attached to the end of a black plastic holder about 4" long. There were no screws to deal with. I just wiggled the plastic holders out, then back in. They are located (in the case of my machine) at the forward and rear ends of the narrow drop slot which leads into the ice holding bin below (as if to aim a beam across the length of the slot. A hand will have to be inserted an inch or two up into the drop slot to feel them along the wall of the slot.
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
The ice maker is the single most hateful appliance I've ever worked on. It is a marvel of electronic theory and complication. The contacts in it are the smallest in all appliancedom. The timer unit costs almost as much as a whole new ice maker. You know where I'm going. Luckily, you probably can replace the unit yourself and avoid a service call, but put a towel below the work area to catch all the screws you will drop.
the infa red sensor should be on constant if the switch on the right is in the on position, if the ben is enpty
if the ben is full the beam will flash interpting the ice maker from making ice untill the level of ice drops down below the holes in the bin then it will make ice again
beam part number if needed is4389102 it comes as a kit with the emitter and reciever boards
