My fridge/freezer will periodically stop cooling. The fan will run constant for 10-12 hrs. but the freezer temp will rise to 40+ degrees. Then it will suddenly cool again. I have vacuumed/ cleaned the...

Lets see if you have a defective defrost timer Click Here=> MTB2176HR Control Panel item number 15 is the defrost timer and should have a hole below it entering the fresh food compartment. Sometimes there is a plastic plug covering hole to hide its opening. Pry plug away and use a flathead screwdriver to turn timer clockwise until compressor either stops or starts. If the compressor stops leave like this for up to 30 minutes. This should be manual defrost. and if it does not come out of defrost gently turn timer again slowly until compressor restarts. If you need to do this the timer will need replaced. Part number=> 68233-3 Look into the rear of the freezer compartment and you see frost building on the rear freezer wall I believe you are not defrosting until your defect defrost time finally drags around to defrost. Now if this is not the case I need you to tell me ASAP because I will have a change in plans, Let me know HERE or here on Fixya, I really have the tools, manuals and can solve this for you, Let me know, Thanks Sea Breeze

The ice maker stoped working about a week ago. And now neither the fridge or freezer are working.

The first thing I would look at is the area around the compressor. themobilian_280.jpg
I want the fan to be running down there. I also need the coils to be cleaned so they don't restrict the air flow. I want the compressor to be warm to the touch but not hot and not cold. If the fan is running and the coils are clean I want to take a closer look at the compressor. The relay on these will simply fall apart over time.themobilian_281.jpg
I want to make sure I am getting power to the compressor. No power down there? We go upstairs to the control. I want to first take a look at the defrost timer or electronic defrost control. I want to make sure the timer is in compressor run mode and is not hung in defrost mode. themobilian_282.jpgI want to check an automatic defrost control for corrosion at the connection. Sometimes yanking it out of its socket will make a better connection and all will be well again.themobilian_283.jpg
If all of that is fine and the compressor is running I want to take a look at the evaporation coils. If they are iced over then I know I either have a bad defrost heater or defrost heater termination thermostat. themobilian_284.jpg
Why do we need a termination thermostat? It activates the heater when the temp in the freezer is below 25f AND the defrost timer or control calls for defrost. You see the defrost heater and terminator are still same whether you have the old tried and true defrost timer or the fancy smancy electronics. The defrost termination thermostat kills the power to the heater when the temp reachs 50f. Why is this important? Because the defrost mode stay on for 20 minutes or longer. If we leave that heater on that long the ice box would be damaged or destroyed. The ice buildup resulted from a failed defrost takes a week or longerthemobilian_285.jpgthemobilian_286.jpg I have more Info Here

Refrigerator does not kick back on after it defrost sometimes but not all the time.

If it is an older model the timer might be hanging up. Remove the timer and give it a few rapid twists and it may go a while longer depending on how bad the humidity is where you live. If it is a newer model then after 40 minutes or so defrost and dwell, the compressor and outside fan comes on but the inside fans do not. This is called post dwell. Both the fan and compressor must run at the same time. If the compressor don't run but the fan does, then you need to check the compressor relay and overload for signs of imminent failure:2a1315a.jpgIf the relay is fine I would look at corrosion on the board terminals.

Is the ge tbx19 defrost clock continious or cumulative?

The timer will advance whenever the cold control is on. (when the compressor is running, or the timer has advanced into a defrost cycle) When the refrig is cold enough (and the timer has not advanced into defrost) the timer will not be advancing. A typical defrost timer will count up 8 hours of compressor run time before going into a 30 minute defrost cycle. (the run time and defrost time can vary greatly from model to model)

Freezer compartment no longer cools. Continuous defrost cycle?

Good day,
Sounds more like the compressor trying to start and can't.
Pull the machine out, remove the rear cover and see if in fact the sound is coming from the compressor.

A defrost timer , tells the refrig when to defrost . Your model does not have a timer . Yours works off a main control board and thermistors .

Refrigerator starts -runs for two weeks, compressor won't restart

It might be but I would first check the condenser to see if it's blocked or if the condenser fan (if it has one) is not working. The "buzzing/humming/ticking" sounds you're hearing is the compressor trying to restart after it became locked down. Excessive pressures in the system or compressor overheating is usually the cause although sometimes the bearings in the compressor simply lock up.
Check to see if the fridge cycles on and off by the thermostat. If it doesn't cycle and just keeps running then the thermostat is bad and that can cause compressor failure thanks to "slugging". If it does then you want to check the defrost timer. Turn the timer's dial until it clicks into defrost and see if it comes out on its own. Check if the compressor has trouble starting after defrost. If it stays in defrost the timer is shot. If the timer times out and the compressor will not restart then the relay might be bad or, the compressor might be going bad.
A 3in1 relay/capacitor/overload might help out and give the unit a little longer time but sooner or later it will go.

Refrigerator and freezer quit

Possible problem may be that you knocked a wire off or the compressor while cleaning or, loosened up or knocked off the plug on the defrost timer. Other possibilities are that the compressor lost a valve or broke a rod from operating under too much pressure and heat over a long period of time. The defrost timer could be bad as well and stuck on defrost. If equipped, the condenser fan may not be running. It's back by the compressor and may be bad, stuck obstructed or unplugged.
You can tell if the compressor is running by placing your hand on it while it's supposed to be running. Avoid the wires. If you feel it vibrating and there's no cooling or if it's really hot and not cooling, the compressor is done or, you sprung a leak while cleaning it. A refrigeration tech will have to check it from there since further tests will require gauges and electronic meters to test the compressor and the electrical components.

Freezer cycling on and off, will freeze then thaw out

You have a defrost timer that has possibly slowed down because it is defective. I need you to time the defrost timer or turn the defrost timer inside the fresh food compartment until the refrigerator compressor stops running. It should remain off for about 20 minutes. If a lot longer and the refrigerator does not defrost regularly about 3 times a day then it needs to be replaced. Yes there could be something other than the timer, but if you need my help I'm here let me know, Thanks, Sea Breeze

Westinghouse side by side fridge is warm but freezer seems alright, checked and found evaporator freezing up not allowing airflow into fridge? Note cleaned all dust from Condensor and still same, fridge...

Locate the defrost timer, turn the clutch head screw until you hear one click. This will actuate the defrost system. After 18-22 minutes the defrost should should have taken place and the compressor should restart. If the compressor does not restart after the time period the timer is at fault and needs to be replaced. Turn the clutch head screw to the second click and the compressor will restart. If defrost does not take place the problem is in the defrost heater circuit. Possibly bad heater or defrost termination switch.
