We dicovered that our refridgerators' freezer is not keeping things frozen....in other words it's too warm. We have tried turning it up a bit and still it's not right. I suspect that the condenser coils probably need cleaning which we can't do til this weekend. My question is by turning the freezer all the way up is there any danger of causing a fire because the coils are too dust covered and it will be working very hard to try and keep things cool?

Re: We dicovered that our freezer is not keeping
The position of the thermostat makes no difference so long as the temperature is not kicking it off. You could aim a small fan at the bottom grille to see if it helps the box to chill. If it makes a difference then you are probably right about the condenser coils. If it makes no difference, you may have a defrost system failure, or low on refrigerant.

it could be 1 of 3 things,1st: the ptc overload on the compressor has welded together and cant cycle on and off/2nd:the cold control is defective,this component is the part you set the units temperature with/3rd:your damper vent door located between the freezer and refrigerator compartments could have frozen open from condensation and cant close to keep the cold out of the refrigerator after the refrige is cool enough,this is behind a plastic grille in the refrigerator and brings in cool air from the freezer
If this freezer is running all of the time and only freezing the walls at the top inside it is a good chance there is deteriation in the piping in the walls eg (rusty pipes) letting the refridgerant escape (common fault) with chest freezers.If it is more than 7 years old it would be advisable to replace it as the repair would probably cost 3 quarters of replacement price.Hope this helps. Kind Regards.
It sounds like you have aproblem with the defrost cycle. Three parts make up defrost system in most refrigerators. The heating element, bimetal and defrost timer, these components need to be checked to determin which is bad. The heating element and bi metal are on the coil behind the freezer back wall, if you have someone who can use a volt ohm meter, with the food removed and refrigerator unplugged ck for resistance on the element if you get a measurment its good, the bimetal will give you a resistance measurment as long as its covered in ice. if these two check ok you may have a bad defrost timer. Id check the bimetal first, hope this helps.
probable reason for this is that the thermostat controls freezer temp and freezer follows suit.
if temp in your garage is low ie in winter, then the fridge doesn't need to switch on and the freezer temp rises.
i know this sounds barmy but it is true
here's what you can check,defrost timer,put frig. out and listen to see if compressor is running,freezer fan listen to see if fan in freezer is running,look to see if you have frost on back of freezer wall,your defrost heater might be bad,also there is a thermonator in the freezer that turns heater on and offhope this help-mike
