KitchenAid KSRG25FTST01 side by side does it have a defrost timer or a board
My side by side is in need of a thermostat or timer or board most likely but I am trying to start troubleshooting with the defrost timer which I cannot locate. I've found no info searching my model number online. Is it a timer or a board? If it's either, where are they located?

If the defrost heater has blown twice in a short period of time and the coils are still freezing up, there may be an issue with the defrost thermostat or the defrost control board. Here are some steps you can take to troubleshoot the issue:
Check the defrost thermostat: Use a multimeter to check the continuity of the defrost thermostat. If the thermostat is open, replace it.
Check the defrost control board: If the thermostat checks out, the problem may be with the defrost control board. Check the board for any signs of damage, such as burned or broken components. If the board appears to be damaged, replace it.
Check the defrost timer: If the thermostat and control board are functioning properly, the issue may be with the defrost timer. Use a multimeter to test the timer for continuity. If the timer is not functioning properly, replace it.
It's important to use the correct parts for your specific model when replacing any components. Double-check that the replacement parts are compatible with your GE model. If you're unsure about the correct parts or how to make these repairs, it may be best to contact a professional appliance repair technician.
4388932 is the part number for the adaptive defrost control located behind your control panel. If your defrost heater and defrost thermostat test ok then by order of deduction you need the board.
The self defrosting feature of your unit has a failed component. Possible defrost heater, defrost thermostat, or timer. The defrost timer may be part of the main circuit board of the unit.
First check to see if the fan in the freezer is running. Also check to see if there is ice build up on the freezer wall, if so then more than likely have a defrost problem. If so, then
Your problem is one or more parts of the defrost system is malfunctioned and in return your problem arises. There are three parts to the system, the defrost timer or in some cases control board, defrost thermostat also known as a bi-metal, and the defrost heater. The defrost system is set up to operate as so. The defrost timer or control board will turn the machine off, in some cases every 8 hours, some 12. During this time period the defrost heaters, located behind the freezer wall and rest underneath the evaporator, yet wires to them run up the side of it, are energized and emit heat that raises upward to melt the ice that has formed on the evaporator coils. The bi-metal or defrost thermostat is at the top of the evaporator. When the heat from the heater starts to reach the bi-metal, it breaks the circuit turning the heater off. The whole purpose of this is because the freezer cool the refridgerator side by drawing air across the coils and blowing to the other side via the evap fan motor. In my opinion, if you change one part of the defrost system change them all because usually when one part fails another will follow, so save yourself the time and the food loss, the cost difference is minute.
If the thermostat behind the left side of the fill tray goes bad, the cycle will stop completely. Cost of thermostat is $20.00. Cost of new icemaker with new motor and everything including thermostat is $45.00, brand new, on EBay plus shipping. Cost for new icemaker from repair shop, $153.00 plus tax. Control board circuit panels each side of freezer compartment will go bad also stopping the ice maker cycle. these control boards come in pairs, one for each side of freezer compartment. Cost for new circuit panel control board from repair shop, $215.00. Cost from EBay brand new circuit control board $45.00 plus $8.00 shipping. Easy to install both, icemaker and control board circuit panels. Phillips screw driver and small socket set is all you need for removing and installing these items.
If the freezer side is working and the refrigerator is not, its either your evaporator fan motor in the freezer side isn't running, or a defrost system problem. Open the freezer door to listen for the fan, and at the same time look to see if you have a build of ice on the back freezer wall. If you do, there is no circulation from the freezer side to cool the ref. The defrost system consist of a defrost timer, defrost thermostat and defrost heaters. The heaters rarely go out, so if you have to change the timer change the defrost thermostat as well since its a cheap part anyway. timer part number is 2188159 and the thermostat part number is 2196155.(called a bi-metal thermostat.)
before i replaced the defrost timer again i would replace the defrost termonator . pt # 2000528 / this could cause the problem and the other is the main board pt 4288656 . both of these could cause this the bi metal thermo may not be reseting as most don't when going bad and the control board is more common and it's prob the problem .. mm / if you were to do a maintaince program you would replace the heater and the bi metal every 4 to 5 yrs as they do ware out .. and ck all fans for speed and air flow and clean coils at lease 1 a year . hope this helps mm ..
The fridge gets its cold air from the freezer through a vent(damper)
between the freezer and fridge.The fan in the freezer blows air through
it.There is a flap you adjust with the
fridge temp. control. Make sure it's opening and closing when you adjust the
fridge temp .
OR.
If the evaporator coils behind the back panel of the freezer
are icing up because of auto defrost failure that will stop the circulation of
cold air and eventually affect the freezer too.
check defrost timer, defrost heater, defrost thermostat. In
most newer models the timer has been replaced by an electronic control board.
If the heater and thermostat are ok it’ll be the control.
You can turn the defrost timer till it clicks
and everything shuts down. The heater should now come on. If it does, replace
the timer. If it doesn't, check the heater and defrost thermostat. Turn the
timer again till everything starts back up to end the defrost cycle.
if you have frost build up on rear wall of freezer section then your unit is not going through defrost. its either defrost heater, defrost thermostat (which are both located on evaporator) or defrost timer
