New defrost control fried in same place as old

Buy a used fridge on ebay, they are very cheap.

Hi,

Many times a freezer and/or refrigeratordo not work right because of a dirty condenser coil...there are also many otherthings that can go wrong. If you are hearing a clicking or buzzing then check out thelast two tips.

If your refrigerator is running but warm, then...

Check out these tips that I wrote about that... it is a great place to starttrouble shooting your unit...and something that you can do rather then callinga repair person to do a simple thing for you...

Refrigerator Condenser Coil Cleaning Refrigerator Repair

Refrigerator Troubleshooting Refrigerator Compressor

Refrigerator Compressor Start Capacitor and Start Relay
Refrigerator or Freezer not Cooling or Getting Cold

Here is what I would do:
I would check to see if the compressor and condenser fan motor is running. If the compressor was hot to the touch that would give me a clue.
That would tell me the relay is stuck in start mode causing the compressor to get hot and quit. I would remove the relay and put my HS410 start pack to see if the compressor comes on and I would check if it was over amping. The amp draw should be around 1 amp. If it is running 7 or 8 amps then the compressor is shot will over heat and die. The fan motor by the compressor should run when the compressor does. So if the compressor is running but not the fan then you need to look at buying a fan motor. If the fan is running but the compressor is not then you need to buy a relay. If all of that is ok I would next listen for the fan motor blowing in the freezer, no fan no cool. Lots of times fans will make a racket if ice begins to build in the evaporator. They will get louder and louder. Then the ice will build to the point the fan won't blow.
I would need to check for a bad defrost heater or terminator if that is the case. Do this test: unplug the ice box and let it sit for 3 or 4 days till it completely thaws out. Then plug it back in. If it begins to work ok then you KNOW you have a defrost problem. Replacing the defrost thermostat and heater is not very difficult, you still need to let it thaw out to do it. Even if you called me out there and I said it was a defrost problem I would still have to leave and come back 3 days later. If you suspect it is the defrost then go ahead and clean out the ice box and let er sit for 3 days. Then until you can fix it just unplug it once a week like grandma did back in the 40s before auto defrost. That's all the smart pills I have. Post a model and I could be a bit more specific because you could have adc or a timer a control board instead of a mercury based control and in that case their is much more to check. For instance if you had an old schoo timer, it might be stuck in defrost. It might just take moving that timer screw forward to get it unstuck. Don't know until I see a model number. More here

My fridge is running but not cold enough: Start out with the easy stuff first...make sure the lights go out when you close the door(s), make sure the doors are closing properly and the gaskets are closing fully and not torn. Check to make sure the evaporator fan in the freezer is working, this fan blows the cold air around. If the fan is not working, possible bad fan motor - check for power to the fan motor and also check the fan switches around the door openings, ( if your fridge has these switches, not all do ). A common problem cropping up in the last several years has been the air damper not opening up and allowing the cold air from the freezer to be blown into the fresh food section ( mostly on SxS refrigerators ). For many years the air damper was manually operated and now we have motorized controlled or temperature controlled or thermister and electronic boards controlling air dampers, and if this device sticks closed the FF section will normally warm up. An example picture of "one" style and an air damper ( called a diffuser by Whirlpool ). Next would be to check the condenser tubing, a good place to start is to make sure the condenser coils are not built up with dust!! Make sure the condenser fan motor is also working properly. Check for any "clicking on and off" noises from the compressor, is the compressor running.
 
The most common fridge "not cooling" problem is a frost free failure. Remove the access panel in the freezer section to expose the evaporator coils. If the coils in the freezer section get plugged up with frost, this frost will block the evaporator fan motor from blowing the cold air around. The fan blade can also hit this frost and either become noisy or stop altogether. Locating the defrost timer can be tricky....they are often hidden behind the back bottom corners of the fridge at the bottom, in the last few years the timers have been located in the ceiling of the fresh food section, and some behind the cold control cover. Once you locate the defrost timer, slowly turn the screw like wheel in the middle of the defrost timer with a straight screwdriver until the fridge shuts off. You are now in defrost. If the defrost heater(s) comes on now, replace the defrost timer and defrost thermostat. If the heater(s) does not come on, you can ohm test the defrost heater for continuity or volt test for 120 volts to the heater(s). If you have no power to the defrost heater(s) you can also bypass the defrost thermostat to see if the defrost heater will come on, join the 2 wires together to bypass the defrost thermostat. If the heater now comes on, replace the defrost timer and defrost thermostat. If the heater itself is bad, defrost the fridge with a hair dryer, replace the defrost heater* and defrost thermostat. If the defrost timer seems "hot" to the touch or is noisy ( like a ticking or screeching noise )...replace it.
*One new safety device added to refrigerators in the last few years has been a in-line fuse added to both sides of the defrost heater. If one of these fuses let's go, you must replace the whole defrost heater, as it comes as an assembly. If the defrost heater does not work, you should check for one of these fuses being open. Check it with a volt meter or ohm meter.
New link from Appliance Repair Aid on how the wiring circuit works for a frost free fridge, the link is here.
On a frost free refrigerator, the cooling coils should be in the freezer section. On a SxS style refrigerator the coils will be behind a cover on the back wall.  On a freezer on top style the coils could be behind the back wall or under the freezer floor. Removing the cover and exposing the evaporator coils could be a valuable tool. Seeing what the cooling coils looks like may help split your not cooling problem. Totally covered coils with white snow is a frost free problem. A ball of ice on the coils and the rest of the cooling coils are bare or only a few coils frosted a little and the rest are bare is an indication of a system problem. Example picture one, example picture two, example picture three. System problems may be a leak in the refrigeration tubing, an inefficient not 100% pumping compressor. 

First take the grill off at the bottom under the doors look at the grate under the frig That is your condenser it will probably be covered in dust clean it off the see if you can fill air blowing under the frig there is a fan under there that keeps that coil cool and it runs around the door to keep condensation from build around the doors if no air is blowing take the back panel behind the Frig and there should be a fan running if the compressor is running this will also cause the compressor to over heat and will not cool as well but it might just need to be cleaned Good luck

I just worked on a FF801W which is supposed to be very similar. The defrost heater in mine was of the glass tube type and located under the evaporator. There was a bimetal thermostat clipped to the top of the evaporator and a thermal fuse (sealed in a clear plastic tube) nearby. The connections were behind a little plastic cover (2 screws) in the back wall just above the evaporator.

Mine was iced up like yours and I had to defrost it with a hair dryer. All the defrosting parts in the freezer compartment turned out to work so I now suspect the defrost timer (down by the compressor). I've marked it and I'm waiting to see if it's turning.

There is a vent that is connected from the freezer down to the fridge right where the fan is,make sure nothing is blocking it.

Hope this helped.Let me know by rating me or

You could also try defrosting the unit completely.

As I said; the fan and compressor run fine but I cannot find the defrost timer. Is it integrated into the control board.
Thanks

i would look behind rear wall of freezer, lower compartment, sounds like a short in the defrost circuit. remove the panel inside freezer and check for possible broken wire s
